Currently, when trying to virsh pool-define/virsh pool-build a new
'dir' pool, if the target directory already exists, virsh
pool-build/virStoragePoolBuild will error out. This is a change of
behaviour compared to eg libvirt 1.2.13
This is caused by the wrong type being used for the dir_create_flags
variable in virStorageBackendFileSystemBuild , it's defined as a bool
but is used as a flag bit field so should be unsigned int (this matches
the type virDirCreate expects for this variable).
This should fix https://bugzilla.gnome.org/show_bug.cgi?id=752417 (GNOME
Boxes) and https://bugzilla.redhat.com/show_bug.cgi?id=1244080
(downstream virt-manager).
The auto-spawn code would originally attempt to spawn the
daemon for both ENOENT and ECONNREFUSED errors from connect().
The various refactorings eventually lost this so we only
spawn the daemon on ENOENT. The result is if the daemon exits
uncleanly, so that the socket is left in the filesystem, we
will never be able to auto-spawn the daemon again.
Resolving an error reporting bug introduced by commit id '761491e' which
just took the return of virStorageBackendRBDCreateImage and used it as
the basis for the message generated. This would generate EPERM regardless
of error seen.
We used to look at the librbd code version and depending on that
we would invoke rbd_create3() or rbd_create().
Since librbd version 0.67.9 we can however tell RBD that it should
create rbd format 2 images even if we invoke rbd_create().
The less options we pass to librbd, the more we can lean on the sane
defaults it uses.
For rbd_create3() we had things like the stripe count and unit hardcoded
in libvirt and that might cause problems down the road.

Make sure sysfs_prefix, when present, is always the first argument
to a function; don't use a different name to refer to it; check
whether it is NULL, and hence SYSFS_SYSTEM_PATH should be used, only
when using it directly and not just passing it down to another
function; always pass down the same value we've been passed when
calling another function.
In commit 641a145d73 I've added code that
resets the balloon memory value to full size prior to resuming the vCPUs
since the size certainly was not reduced at that point.
Since qemuProcessStart is used also in code paths with already booted
up guests (migration, save/restore) the assumption is not entirely true
since the guest might already been running before.
This patch adds a function that queries the monitor rather than using
the full size since a balloon event would not be reissued in case we are
recovering a saved migration state.
Additionally the new function is used also when reconnecting to a VM
after libvirtd restart since we might have missed a few balloon events
while libvirtd was not running.

In one of my previous ptaches (bcd9a564) I've tried to fix the problem

not result in desired effect. See the original commit for more info.
But, the commit I wrote had a bug: when NUMA parameters are changed on

nodeset. Due to a typo a condition was mis-evaluated.

This patch resolves a situation where a core is defective and is not

could be brought online if the socket is added. In this case the present
mask contains the cpu's that are actually there in the sockets even though
they might be offline for some reason. This patch excludes the cpu's that
are offline because the socket is defective/empty by checking the present
mask before reading the cpu directory. Otherwise, the nodeinfo on such

After Jirka's migration patches libvirt is listening on migration
events from qemu instead of actively polling on the monitor. There is,
however, a little regression (introduced in 6d2edb6a42). The
problem is, the current status of migration job is updated in
qemuProcessHandleMigrationStatus if and only if migration job was
started. But eventually every asynchronous job may result in
migration. Therefore, since this job is not strictly a
migration job, internal state was not updated and later checks failed:

When QEMU exits on destination during migration, the source reports
either success (if the failure happened at the very end) or unhelpful
"unexpectedly failed" error message. However, the Finish API called on
the destination may report a real error so let's use it instead of the
generic one.
Signed-off-by: Jiri Denemark <jdenemar@redhat.com>
virDomainMigrateFinish* APIs were unfortunately designed to return the
pointer to the domain on destination and NULL on error. This looks OK in
normal cases but the same API is also called when we know migration
failed and thus we expect Finish to return NULL even if it actually did
all it was supposed to do without any error. The call is defined to
return nonnull domain pointer over RPC, which means returning NULL will
always result in an error being send. If this was not in fact an error,
the API itself wouldn't set anything to the thread local virError, which
makes the RPC layer come up with it's own "Library function returned
error but did not set virError" error.
This is quite confusing and also hard to detect by the caller. This
patch adds a special error code which can be used to check that Finish
successfully aborted migration.

Some guests lock the tray and QEMU eject command will simply fail to

error, from monitor. If we receive that event, we know, that the guest
properly reacted to the eject request, unlocked the tray and opened it.
In this case, we need to run the command again to actually eject the

This patch reverts commit 4749d82a which tried to tweak the logic in

volume building within a specific storage backend. If that failed, we

build and delete the volume from the pool (even though it didn't exist - this
truly depends on the backend).
I misunderstood the base idea to be able to poll the status of the volume

Commit 2a31c5f0 introduced support for storage pool state XMLs, however
it also introduced a regression:
if (!virstoragePoolObjIsActive(pool)) {
virStoragePoolObjUnlock(pool);
continue;
}
The idea behind this was that since we've got state XMLs and the pool
wasn't marked as active by autostart routine (if the autostart flag had been
set earlier), the pool is inactive and we can leave it be and continue with
other pools. However, filesystem type pools like fs,dir, possibly netfs are
supposed to be active if the filesystem is mounted on the host. And this is
exactly where the regression occurs, e.g. pool type 'dir' which has been
previously destroyed and marked as !autostart gets filtered out
by the condition above.
The resolution should be simply to remove the condition completely,
all pools will get their 'active' flag updated by check callback and if
they do not support such callback, the logic doesn't change and such
pools will be inactive by default (e.g. RBD, even if a state XML exists).
