[libvirt] [PATCH] virfile: Fix virFileExists commentary
by Erik Skultety
Arguably though, function returning only on success is a very
interesting, although quite impractical concept. Also, the errno isn't
and shouldn't be preserved in this case, since the errno can be directly
fed to the virReportSystemError.

[libvirt] [PATCH v2 0/3] introduce virBufferEscapeN and fix escape bug
by Pavel Hrdina
I've dropped the STRCAT patches in v2. The whole purpose of the STRCAT was
to avoid calling *strcspn* several times but it was probably a bad call.
Now we call that function for each pair but if no escaping is required
we at least don't allocate the structure for that pair and later in the
*virBufferEscapeN* we only iterate over the pairs that will escape at least
one character.
Pavel Hrdina (3):
util: virbuffer: introduce virBufferEscapeN
util: virqemu: introduce virQEMUBuildBufferEscape
qemu: properly escape socket path for graphics

Re: [libvirt] A question for external snapshots with flag“VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE”

When we create consistent active external snapshots with flag “VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE” , the qemuDomainSnapshotFSFreeze will be called firstly to freeze all filesystems in vm, and then create snapshots. For windows vm, freezing filesystems used by vss service. If IO pressure in vm is too big or internal error happened in vss , freezing filesytems will failed , and qemuDomainSnapshotFSFreeze returns 0 which meaning that no filesystems are frozen. In the function qemuDomainSnapshotCreateActiveExternal, libvirt creates external snapshots all the same in such a situation that qemuDomainSnapshotFSFreeze returns 0, but the created snapshots are not consistent snapshots in such a situation . So shouldn't we abandon creating snapshots and goto cleanup in the situation that qemuDomainSnapshotFSFreeze returns 0?

[libvirt] [PATCH] qemuProcessInit: Jump onto correct label in case of error
by Michal Privoznik
After eca76884ea in case of error in qemuDomainSetPrivatePaths()
in pretended start we jump to stop. I've changed this during
review from 'cleanup' which turned out to be correct. Well, sort
of. We can't call qemuProcessStop() as it decrements
driver->nactive and we did not increment it. However, it calls
virDomainObjRemoveTransientDef() which is basically the only
function we need to call. So call that function and goto cleanup;

[libvirt] [PATCH 00/13] Add TLS support for migration
by John Ferlan
Patches 1, 3 -> 9 are primarily quite a bit of code motion in order to allow
reuse of the "core" of the chardev TLS code.
Theoretically speaking of course, these patches should work - I don't
have a TLS and migration environment to test with, so between following
the qemu command model on Daniel's blog and prior experience with the
chardev TLS would
I added the saving of a flag to the private qemu domain state, although
I'm not 100% sure it was necessary. At one time I created the source TLS
objects during the Begin phase, but later decided to wait until just
before the migration is run. I think the main reason to have the flag
would be a restart of libvirtd to let 'something' know migration using
TLS was configured. I think it may only be "necessary" in order to
repopulate the migSecinfo after libvirtd restart, but it's not entirely
clear. By the time I started thinking more about while writing this cover
letter it was too late to just remove.
Also rather than create the destination host TLS objects on the fly,
I modified the command line generation. That model could change to adding
the TLS objects once the destination is started and before the params are
set for the migration.
This 'model' is also going to be used for the NBD, but I figured I'd get
this posted now since it was already too long of a series.
John Ferlan (13):
qemu: Create #define for TLS configuration setup.
conf: Introduce migrate_tls_x509_cert_dir
qemu: Rename qemuAliasTLSObjFromChardevAlias
qemu: Introduce qemuDomainSecretMigrate{Prepare|Destroy}
qemu: Refactor hotplug to introduce qemuDomain{Add|Del}TLSObjects
qemu: Refactor qemuDomainGetChardevTLSObjects to converge code
qemu: Move qemuDomainSecretChardevPrepare call
qemu: Move qemuDomainPrepareChardevSourceTLS call
qemu: Introduce qemuDomainGetTLSObjects
qemu: Add TLS params to _qemuMonitorMigrationParams
Add new migration flag VIR_MIGRATE_TLS
qemu: Set up the migrate TLS objects for target
qemu: Set up the migration TLS objects for source

[libvirt] [RFC PATCH 00/12] Add block write threshold event
by Peter Krempa
Since I'm a procrastinator and I wanted to do this after full node-name support
is added I'm kind of late for this release here. Since oVirt is asking for this
feature for a very long time I would like to deliver it ASAP though.
This series adds a event which is fired once a guest writes beyond a configured
offset in the backing file. The threshold offset is configurable via a new API.
This series is in RFC state since I did not manage to polish few details mostly
connected to node names:
- currently only the top level image can be selected
- some blockjobs may clear the remembered node names and thus break this
( re-detection of the backing chain needs to be connected with node name
detection )
- the node name detection code is VERY crude
- I'm not sure how well it plays with qcow images, since I select only the top
level node (qcow protocol) rather than the file backing it
- the documentation probably sucks since I did not proof-read
Any feedback is welcome.

[libvirt] [PATCH] qemu: Don't update physical storage size of empty drives
by Peter Krempa
Previously the code called virStorageSourceUpdateBlockPhysicalSize which
did not do anything on empty drives since it worked only on block
devices. After the refactor in c5f6151390 it's called for all devices
and thus attempts to deref the NULL path of empty drives.
Add a check that skips the update of the physical size if the storage
source is empty.
