qmp_block_resize()
RH-Author: Kevin Wolf <kwolf@redhat.com>
RH-MergeRequest: 164: block: Fix hangs in qmp_block_resize()
RH-Bugzilla: 2185688

RH-Commit: [2/4] 7ac7e34821cfc8bd5f0daadd7a1c4a5596bc60a6 (kmwolf/centos-qemu-kvm)
This QMP handler runs in a coroutine, so it must use the corresponding
no_co_wrappers instead.

RH-Commit: [1/4] 8ebf8486b082c30ca1b39a6ede35e471eaaccfa3 (kmwolf/centos-qemu-kvm)
These functions must not be called in coroutine context, because they
need write access to the graph.

RH-Commit: [4/4] 8d31752d1e6e8c6a422d68d9cb2251fbc34b7aef (kmwolf/centos-qemu-kvm)
This tests that trying to resize an image with QMP block_resize doesn't
hang or otherwise fail when the image is attached to a device running in
an iothread.
This is a regression test for the recent fix that changed
qmp_block_resize, which is a coroutine based QMP handler, to avoid
calling no_coroutine_fns directly.

RH-Commit: [3/4] 038d4718c0ee7a17ff5e6f4af8fc04d07e452f8d (kmwolf/centos-qemu-kvm)
This is a downstream-only patch that is necessary because the default
CPU in RHEL is marked as deprecated. This makes test cases fail due to
the warning in the output:
qemu-system-x86_64: warning: CPU model qemu64-x86_64-cpu is deprecated -- use at least 'Nehalem' / 'Opteron_G4', or 'host' / 'max'

Instead of print it to STDERR, bring the error upwards so that it can be
reported via QMP responses.
E.g.:
{ "execute": "migrate-set-capabilities" ,
"arguments": { "capabilities":
[ { "capability": "postcopy-ram", "state": true } ] } }
{ "error":
{ "class": "GenericError",

Subject: [PATCH 01/56] migration: Attempt disk reactivation in more failure

RH-Author: Eric Blake <eblake@redhat.com>

RH-Commit: [1/1] 5999b747b314641259d3b8809033b057805eed3f (ebblake/centos-qemu-kvm)
Commit fe904ea824 added a fail_inactivate label, which tries to
reactivate disks on the source after a failure while s->state ==
MIGRATION_STATUS_ACTIVE, but didn't actually use the label if
qemu_savevm_state_complete_precopy() failed. This failure to
reactivate is also present in commit 6039dd5b1c (also covering the new
s->state == MIGRATION_STATUS_DEVICE state) and 403d18ae (ensuring
s->block_inactive is set more reliably).
Consolidate the two labels back into one - no matter HOW migration is
failed, if there is any chance we can reach vm_start() after having
attempted inactivation, it is essential that we have tried to restart
disks before then. This also makes the cleanup more like
migrate_fd_cancel().

RH-Commit: [22/50] 10c9be528b9fcfae93f1a12fcd09db1a69e58f64 (peterx/qemu-kvm)
We move there all capabilities helpers from migration.c.
Signed-off-by: Juan Quintela <quintela@redhat.com>
Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com>

Following David advise:
- looked through the history, capabilities are newer than 2012, so we
can remove that bit of the header.
- This part is posterior to Anthony.
Original Author is Orit. Once there,
I put myself. Peter Xu also did quite a bit of work here.
Anyone else wants/needs to be there? I didn't search too hard
because nobody asked before to be added.
What do you think?

RH-Commit: [7/50] 90e395de66aa32b886cf151f7996a680190471f5 (peterx/qemu-kvm)
Using MgrationStats as type for ram_counters mean that we didn't have
to re-declare each value in another struct. The need of atomic
counters have make us to create MigrationAtomicStats for this atomic
counters.
Create RAMStats type which is a merge of MigrationStats and
MigrationAtomicStats removing unused members.

RH-Commit: [23/50] 4809b1091edee38bd222af41b6313133705785c7 (peterx/qemu-kvm)
Once that we are there, we rename the function to migrate_colo() to be
consistent with all other capabilities.

RH-Commit: [28/50] fc8bee0f691a96e6bd0b41f2511abe507b81fea5 (peterx/qemu-kvm)
Once that we are there, we rename the function to migrate_xbzrle()
to be consistent with all other capabilities.
We change the type to return bool also for consistency.

Once that we are there, we rename the function to
migrate_zero_copy_send() to be consistent with all other capabilities.
We can remove the CONFIG_LINUX guard. We already check that we can't
setup this capability in migrate_caps_check().

RH-Commit: [15/50] 89db3c8b167c0f411ba95ce2730540c0e8f1206b (peterx/qemu-kvm)
Rest of counters that refer to pages has a _pages suffix.
And historically, this showed the number of pages composed of the same
character, here comes the name "duplicated". But since years ago, it
refers to the number of zero_pages.

RH-Commit: [16/50] 7df8b946918def9657bbe357861a6d72b5399ac6 (peterx/qemu-kvm)
Rest of counters that refer to pages has a _pages suffix.
And historically, this showed the number of full pages transferred.
The name "normal" refered to the fact that they were sent without any
optimization (compression, xbzrle, zero_page, ...).

RH-Commit: [4/50] 9f055b526edd06a3440999d5de91e5d624678c7d (peterx/qemu-kvm)
There should be no paths from a coroutine_fn to aio_poll, however in
practice coroutine_mixed_fn will call aio_poll in the !qemu_in_coroutine()
path. By marking mixed functions, we can track accurately the call paths
that execute entirely in coroutine context, and find more missing
coroutine_fn markers. This results in more accurate checks that
coroutine code does not end up blocking.
If the marking were extended transitively to all functions that call
these ones, static analysis could be done much more efficiently.
However, this is a start and makes it possible to use vrc's path-based
searches to find potential bugs where coroutine_fns call blocking functions.

It is only used there, so we can make it static.
Once there, remove spice.h that it is not used.

RH-Commit: [3/50] 121aeeda8a019f79dba6c077c7018bd1c86f3d71 (peterx/qemu-kvm)
Postcopy requires the memory support userfaultfd to work. Right now we
check it but it's a bit too late (when switching to postcopy migration).
Do that early right at enabling of postcopy.
Note that this is still only a best effort because ramblocks can be
dynamically created. We can add check in hostmem creations and fail if
postcopy enabled, but maybe that's too aggressive.
Still, we have chance to fail the most obvious where we know there's an
existing unsupported ramblock.

It is clear from the context what that means, and such a long name
with the extra long names of the capabilities make very difficilut to
stay inside the 80 columns limit.

RH-Commit: [5/50] 534c0e13362dfc994fa90c79bfb5ed6ee8c27dfc (peterx/qemu-kvm)
It does not even pair with a qatomic_mb_set(), so it is clearer to use
load-acquire in this case; they are synonyms.

RH-Commit: [20/50] a587bb001b51a1f9fdf2fcfb0978bb931ae443b6 (peterx/qemu-kvm)
It has nothing to do with migration, except for the "migrate" in the
name of the command. Move it with the rest of the ui commands.

RH-Commit: [1/50] 8970b5ae611a933d693e0c90cbf4eda073635494 (peterx/qemu-kvm)
This new helper fetches file system type for a fd. Only Linux is
implemented so far. Currently only tmpfs and hugetlbfs are defined,
but it can grow as needed.
