Subject: [PATCH] RHEL: Enable usage of x-blockdev-reopen
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
RHEL-only
Introduce a new capability QEMU_CAPS_BLOCKDEV_REOPEN_COM_REDHAT_AV_8_2_0_API
based on the presence of '__com.redhat_rhel-av-8_2_0-api' feature for
'x-blockdev-reopen' which states that reopen works for what libvirt
is going to use it and wire up code to call the x- prefixed command.
This implementation will become dormant once qemu starts supporting
upstream-stable blockdev-reopen.
https://bugzilla.redhat.com/show_bug.cgi?id=1799013
Starting with libvirt-7.6, upstream has adapted to the new format of
arguments so this patch was modified to support blockdev-reopen which
takes an array of nodes to reopen.

Subject: [PATCH] RHEL: Hack around changed Broadwell/Haswell CPUs
RHEL-only
Upstream tried to solve the change of Broadwell and Haswell CPUs by
removing rtm and hle features from the corresponding CPU models for new
machine types. Then they reverted this and introduced new *-noTSX models
instead. However, the original fix was backported to RHEL.
This patch makes sure Broadwell and Haswell will always contain rtm and
hle features regardless on RHEL version or machine type used.

Subject: [PATCH] RHEL: Remove <glib-2.64.0 workaround for GSource race
https://bugzilla.redhat.com/show_bug.cgi?id=2045879
This is to accommodate for RHEL 8 downstream glib being fixed with a backport in
version 2.56.4-12 (Bug 1948988). Another reason for that is that our workaround
does not play nice with a fixed glib, leading to libvirt not properly
dereferencing the monitor socket, eventually leading to EMFILE: Too many open
files.

Subject: [PATCH] RHEL: virscsi: Introduce and use
virSCSIDeviceGetUnprivSGIOSysfsPath()
When constructing a path to the 'unpriv_sgio' file of given SCSI
device we don't need to go through /dev/* and major() + minor()
path. The generated path points to
/sys/dev/block/MAJ:MIN/queue/unpriv_sgio which is wrong if the
SCSI device in question is not a block device. We can generate a
different path: /sys/bus/scsi/devices/X:X:X:X/unpriv_sgio where
the file is directly accessible regardless of the SCSI device
type.

Subject: [PATCH] Revert "report error when virProcessGetStatInfo() is unable
to parse data"
This reverts commit 938382b60ae5bd1f83b5cb09e1ce68b9a88f679a.
Turns out, the commit did more harm than good. It changed
semantics on some public APIs. For instance, while
qemuDomainGetInfo() previously did not returned an error it does
now. While the calls to virProcessGetStatInfo() is guarded with
virDomainObjIsActive() it doesn't necessarily mean that QEMU's
PID is still alive. QEMU might be gone but we just haven't
realized it (e.g. because the eof handler thread is waiting for a
job).

Subject: [PATCH] conf: Introduce memory allocation threads
Since its v5.0.0 release QEMU is capable of specifying number of
threads used to allocate memory. It defaults to 1, which may be
too low for humongous guests with gigantic pages.
In general, on QEMU cmd line level it is possible to use
different number of threads per each memory-backend-* object, in
practical terms it's not useful. Therefore, use <memoryBacking/>
to set guest wide value and let all memory devices 'inherit' it,
silently. IOW, don't introduce per device knob because that would
only complicate things for a little or no benefit.

Subject: [PATCH] domain_conf: Format iothread IDs more often
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When formatting IOThreads (in virDomainDefIOThreadsFormat()), we
may only output the number of IOThreads, or the full list of IOThreads too:
<iothreads>4</iothreads>
<iothreadids>
<iothread id='1' thread_pool_max='10'/>
<iothread id='2' thread_pool_min='2' thread_pool_max='10'/>
<iothread id='3'/>
<iothread id='4'/>
</iothreadids>
Now, the deciding factor here is whether those individual
IOThreads were so called 'autofill-ed' or user provided. Well, we
need to take another factor in: if an IOThread has pool size
limit set, then we ought to format the full list.
But how can we get into a situation when a thread is autofilled
(i.e. not provided by user in the XML) and yet it has pool size
limit set? virDomainSetIOThreadParams() is the answer.
Sure, we could also unset the autofill flag whenever a pool size
limit is being set. But this approach allows us to not format
anything if the limits are reset (we don't lose the autofill
information).

Subject: [PATCH] node_device: Treat NVMe disks as regular disks
Unfortunately, udev doesn't set ID_TYPE attribute for NVMe disks,
therefore we have to add another case into udevKludgeStorageType()
to treat /dev/nvme* devlinks as any other disk.

Subject: [PATCH] qemu: Always assume support for
QEMU_CAPS_MIGRATION_PARAM_XBZRLE_CACHE_SIZE
The 'xbzrle-cache-size' parameter was added in qemu-2.11 thus all
supported qemu versions now use the new code path.
Signed-off-by: Peter Krempa <pkrempa@redhat.com>

(cherry picked from commit 06e0ba3da71ec6c58024efe57d0f55d3d1352d60)
This commit is not strictly needed for fixing the following BZ, but it
removes a code which will be never executed in RHEL 9 and backporting it
avoids conflicts with the actual bug fix.

Subject: [PATCH] qemu: Make IOThread changing more robust
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There are three APIs that allow changing IOThreads:
virDomainAddIOThread()
virDomainDelIOThread()
virDomainSetIOThreadParams()
In case of QEMU driver these are handled by
qemuDomainChgIOThread() which attempts to be versatile enough to
work on both inactive and live domain definitions at the same
time. However, it's a bit clumsy - when a change to live
definition succeeds but fails in inactive definition then there's
no rollback. And somewhat rightfully so - changes to live
definition are in general harder to roll back. Therefore, do what
we do elsewhere (qemuDomainAttachDeviceLiveAndConfig(),
qemuDomainDetachDeviceAliasLiveAndConfig(), ...):
1) do the change to inactive XML first,
2) in fact, do the change to a copy of inactive XML,
3) swap inactive XML and its copy only after everything
succeeded.

Subject: [PATCH] qemu: Restore original memory locking limit on reconnect
Commit v8.4.0-287-gd4d3bb8130 tried to make sure the original
pre-migration memory locking limit is restored at the end of migration,
but it missed the case when libvirt daemon is restarted during
migration which needs to be aborted on reconnect.
And if this was not enough, I forgot to actually save the status XML
after setting the field in priv (in the commit mentioned above and also
in v8.4.0-291-gd375993ab3).

Subject: [PATCH] qemu: Validate domain definition even on migration
When we are about to spawn QEMU, we validate the domain
definition against qemuCaps. Except when domain is/was already
running before (i.e. on incoming migration, snapshots, resume
from a file). However, especially on incoming migration it may
happen that the destination QEMU is different to the source
QEMU, e.g. the destination QEMU may have some devices disabled.
And we have a function that validates devices/features requested
in domain XML against the desired QEMU capabilities (aka
qemuCaps) - it's virDomainDefValidate() which calls
qemuValidateDomainDef() and qemuValidateDomainDeviceDef()
subsequently.
But the problem here is that the validation function is
explicitly skipped over in specific scenarios (like incoming
migration, restore from a snapshot or previously saved file).
This in turn means that we may spawn QEMU and request
device/features it doesn't support. When that happens QEMU fails
to load migration stream:
qemu-kvm: ... 'virtio-mem-pci' is not a valid device model name
(NB, while the example shows one particular device, the problem
is paramount)
This problem is easier to run into since we are slowly moving
validation from qemu_command.c into said validation functions.
The solution is simple: do the validation in all cases. And while
it may happen that users would be unable to migrate/restore a
guest due to a bug in our validator, spawning QEMU without
validation is worse (especially when you consider that users can
supply their own XMLs for migrate/restore operations - these were
never validated).

Subject: [PATCH] qemu: don't call qemuMigrationSrcIsAllowedHostdev() from
qemuMigrationDstPrepareFresh()
This call to qemuMigrationSrcIsAllowedHostdev() (which does a
hardcoded fail of the migration if there is any PCI or mdev hostdev
device in the domain) while doing the destination side of migration
prep was found once the call to that same function was removed from
the source side migration prep (commit 25883cd5).
According to jdenemar, for the V2 migration protocol, prep of the
destination is the first step, so this *was* the proper place to do
the check, but for V3 migration this is in a way redundant (since we
will have already done the check on the source side (updated by
25883cd5 to query QEMU rather than do a hardcoded fail)).
Of course it's possible that the source could support migration of a
particular VFIO device, but the destination doesn't. But the current
check on the destination side is worthless even in that case, since it
is just *always* failing rather than querying QEMU; and QEMU can't be
queried at the point where the destination check is happening, since
it isn't yet running.
Anyway QEMU should complain when it's started if it's going to fail,
so removing this check should just move the failure to happen a bit
later. So the best solution to this problem is to simply remove the
hardcoded check/fail from qemuMigrationDstPrepareFresh() and rely on
QEMU to fail if it needs to.

The new code that queries QEMU about migration blockers was put at the
top of qemuMigrationSrcIsAllowed(), but that function can also be
called in the case of offline migration (ie when the domain is
inactive / QEMU isn't running). This check should have been put inside
the "if (!(flags & VIR_MIGRATE_OFFLINE))" conditional, so let's move
it there.

Subject: [PATCH] qemu: new function to retrieve migration blocker reasons from
QEMU
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since QEMU 6.0, if migration is blocked for some reason,
'query-migrate' will return an array of error strings describing the
migration blockers. This can be used to check whether there are any
devices, or other conditions, that would cause migration to fail.
This patch adds a function that sends this query via a QMP command and
returns the resulting array of reasons. qemuMigrationSrcIsAllowed()
will be able to use the new function to ask QEMU for migration
blockers, instead of the hardcoded guesses that libvirt currently has.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
vDPA devices will be migratable soon, so we shouldn't unconditionally
block migration of any domain with a vDPA device. Instead, we should
rely on QEMU to make the decision when that info is available from the
query-migrate QMP command (QEMU versions too old to have that info in
the results of query-migrate don't support migration of vDPA devices,
so in that case we will continue to unconditionally block migration).

Subject: [PATCH] qemu: skip hardcoded hostdev migration check if QEMU can do
it for us
libvirt currently will block migration for any vfio-assigned device
unless it is a network device that is associated with a virtio-net
failover device (ie. if the hostdev object has a teaming->type ==
VIR_DOMAIN_NET_TEAMING_TYPE_TRANSIENT).
In the future there will be other vfio devices that can be migrated,
so we don't want to rely on this hardcoded block. QEMU 6.0+ will
anyway inform us of any devices that will block migration (as a part
of qemuDomainGetMigrationBlockers()), so we only need to do the
hardcoded check in the case of old QEMU that can't provide that
information.

Subject: [PATCH] qemuDomainSetIOThreadParams: Accept VIR_DOMAIN_AFFECT_CONFIG
flag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It was always possible to modify the inactive XML, because
VIR_DOMAIN_AFFECT_CURRENT (= 0) is accepted implicitly. But now
that the logic when changing both config and live XMLs is more
robust we can accept VIR_DOMAIN_AFFECT_CONFIG flag too.

Subject: [PATCH] qemuDomainSetupDisk: Initialize 'targetPaths'
Compiler isn't able to see that 'virDevMapperGetTargets' in cases e.g.
when the devmapper isn't available may not initialize the value in the
pointer passed as the second argument.
The usage 'qemuDomainSetupDisk' lead to an accidental infinite loop as
previous calls apparently doctored the stack to a point where
'g_slist_concat' would end up in an infinite loop trying to find the end
of the list.

Subject: [PATCH] qemu_capabilities: Detect memory-backend-*.prealloc-threads
property
The prealloc-threads is property of memory-backend class which is
parent to the other three classes memory-backend-{ram,file,memfd}.
Therefore the property is present for all, or none if QEMU is
older than v5.0.0-rc0~75^2~1^2~3 which introduced the property.
Anyway, the .reserve property is the same story, and we chose
memory-backend-file to detect it, so stick with our earlier
decision and use the same backend to detect this new property.

Message-Id: <e4e8b74f2cf090c8b29efcd3ceac4e4c4d07b929@dist-git>
From: Michal Privoznik <mprivozn@redhat.com>

Subject: [PATCH] qemu_command: Generate memory only after controllers
Currently, memory device (def->mems) part of cmd line is
generated before any controller. In majority of cases it doesn't
matter because neither of memory devices live on a bus that's
created by an exposed controller (e.g. there's no DIMM
controller, at least not exposed). Except for virtio-mem and
virtio-pmem, which do have a PCI address. And if it so happens
that the device goes onto non-default bus (pci.0) starting such
guest fails, because the controller that creates the desired bus
wasn't processed yet. QEMU processes arguments in order.
For instance, if virtio-mem has address with bus='0x01' QEMU
refuses to start with the following message:
Bus 'pci.1' not found
Similarly for virtio-pmem. I've successfully tested migration and
changing the order does not affect migration stream.

These happened because downstream we don't use JSON for -device,
but upstream we do (as of 1a691fe1c84090da80a652c4c80ac00a6134a69b).

Subject: [PATCH] qemu_command: Generate prealloc-threads property
Let's generate prealloc-threads property onto the cmd line if
domain configuration requests so.

Subject: [PATCH] qemu_migration: Acquire correct job in
qemuMigrationSrcIsAllowed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit 62627524607f added the acquiring of a job, but it is not always
VIR_ASYNC_JOB_MIGRATION_OUT, so the code fails when doing save or anything else.
Correct the async job by passing it from the caller as another parameter.

Subject: [PATCH] qemu_migration: Apply max-postcopy-bandwidth on post-copy
resume
When resuming post-copy migration users may want to limit the bandwidth
used by the migration and use a value that is different from the one
specified when the migration was originally started.

Subject: [PATCH] qemu_migration: Store original migration params in status XML
We keep original values of migration parameters so that we can restore
them at the end of migration to make sure later migration does not use
some random values. However, this does not really work when libvirt
daemon is restarted on the source host because we failed to explicitly
save the status XML after getting the migration parameters from QEMU.
Actually it might work if the status XML is written later for some other
reason such as domain state change, but that's not how it should work.

MIME-Version: 1.0

The code is run with an async job and thus needs to make sure a nested
job is acquired before entering the monitor.
While touching the code in qemuMigrationSrcIsAllowed I also fixed the
grammar which was accidentally broken by v8.5.0-140-g2103807e33.

Subject: [PATCH] qemu_migration_params: Avoid deadlock in
qemuMigrationParamsReset
In my recent comnmit v8.5.0-188-gc47f1abb81 I accidentally moved
qemuMigrationParamsResetTLS after qemuDomainObjEnterMonitorAsync not
noticing qemuMigrationParamsResetTLS will try to enter the monitor
again. The second call will time out and return with a domain object
locked. But we're still in monitor section and the object should be
unlocked which means qemuDomainObjExitMonitor will deadlock trying to
lock it again.

Subject: [PATCH] qemu_migration_params: Refactor qemuMigrationParamsReset
Because qemuMigrationParamsReset used to call qemuMigrationParamsApply
for resetting migration capabilities and parameters, it did not work
well since commit v5.1.0-83-ga1dec315c9 which only allowed capabilities
to be set from an async job. However, when reconnecting to running
domains after daemon restart we do not have an async job. Thus the
capabilities were not properly reset in case the daemon was restarted
during an ongoing migration. We need to avoid calling
qemuMigrationParamsApply to make sure both parameters and capabilities
can be reset by a normal job.

Subject: [PATCH] qemu_migration_params: Replace qemuMigrationParamTypes array
We will need to annotate individual parameters a bit more than just
noting their type. Let's introduce qemuMigrationParamInfo replacing
simple qemuMigrationParamTypes with an array of structs.

Subject: [PATCH] rpc: Pass OPENSSL_CONF through to ssh invocations
It's no longer possible for libvirt to connect over the ssh transport
from RHEL 9 to RHEL 5. This is because SHA1 signatures have been
effectively banned in RHEL 9 at the openssl level. They are required
to check the RHEL 5 host key. Note this is a separate issue from
openssh requiring additional configuration in order to connect to
older servers.
Connecting from a RHEL 9 client to RHEL 5 server:
$ cat ~/.ssh/config
Host 192.168.0.91
KexAlgorithms +diffie-hellman-group14-sha1
MACs +hmac-sha1
HostKeyAlgorithms +ssh-rsa
PubkeyAcceptedKeyTypes +ssh-rsa
PubkeyAcceptedAlgorithms +ssh-rsa
$ virsh -c 'qemu+ssh://root@192.168.0.91/system' list
error: failed to connect to the hypervisor
error: Cannot recv data: ssh_dispatch_run_fatal: Connection to 192.168.0.91 port 22: error in libcrypto: Connection reset by peer
"error in libcrypto: Connection reset by peer" is the characteristic
error of openssl having been modified to disable SHA1 by default.
(You will not see this on non-RHEL-derived distros.)
You could enable the legacy crypto policy which downgrades security on
the entire host, but a more fine-grained way to do this is to create
an alternate openssl configuration file that enables the "forbidden"
signatures. However this requires passing the OPENSSL_CONF
environment variable through to ssh to specify the alternate
configuration. Libvirt filters out this environment variable, but
this commit allows it through. With this commit:
$ cat /var/tmp/openssl.cnf
.include /etc/ssl/openssl.cnf
[openssl_init]
alg_section = evp_properties
[evp_properties]
rh-allow-sha1-signatures = yes
$ OPENSSL_CONF=/var/tmp/openssl.cnf ./run virsh -c 'qemu+ssh://root@192.168.0.91/system' list
root@192.168.0.91's password:
Id Name State
--------------------
Essentially my argument here is that OPENSSL_CONF is sufficiently
similar in nature to KRB5CCNAME, SSH* and XAUTHORITY that we should
permit it to be passed through.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

The PCIe 5.0 and PCIe 6.0 standards define new link speeds:
32GT/s and 64GT/s, respectively. Update our internal enum to
include these new speeds. Otherwise we format incorrect XML:
<pci-express>
<link validity='cap' port='0' speed='(null)' width='16'/>
<link validity='sta' speed='16' width='16'/>
</pci-express>
Like all "good" specifications, these are also locked behind a
login portal. But we can look at pciutils' source code: [1] and
[2].

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Our man page already documents that iothreadset has --config
argument. Well, it doesn't really. Normally, I'd just fix the man
page, but with recent work on the API it's possible to tweak
values for inactive XML too. Therefore, implement the --config
argument for the command.

Subject: [PATCH] virsh: Require --xpath for *dumpxml
Historically, the dumpxml command reject any unknown arguments,
for instance:
virsh dumpxml fedora xxx
However, after v8.5.0-rc1~31 the second argument ('xxx') is
treated as an XPath, but it's not that clearly visible.
Therefore, require the --xpath switch, like this:
virsh dumpxml fedora --xpath xxx
Yes, this breaks already released virsh, but I think we can argue
that the pool of users of this particular function is very small.
We also document the argument being mandatory:
dumpxml [--inactive] [--security-info] [--update-cpu] [--migratable]
[--xpath EXPRESSION] [--wrap] domain
The sooner we do this change, the better.
The same applies for other *dumpxml functions (net-dumpxml,
pool-dumpxml, vol-dumpxl to name a few).
