Subject: [PATCH] qemu: don't try to query QEMU about migration blockers during
offline migration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.

Subject: [PATCH] qemu: query QEMU for migration blockers before our own
harcoded checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since QEMU 6.0, if QEMU knows that a migration would fail,
'query-migrate' will return an array of error strings describing the
migration blockers. This can be used to check whether there are any
devices/conditions blocking migration.
This patch adds a call to this query at the top of
qemuMigrationSrcIsAllowed().

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.

Correct the async job by passing it from the caller as another parameter.

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).
