Can you also put the vdsm, libvirt and qemu packages?
Thanks,

Thanks Steve.
from the logs I can see that the create snapshot succeeds and that
the vm is resumed.
the vm moves to pause as part of libvirt flows:
2014-02-02 14:41:20.872+0000: 5843: debug :
qemuProcessHandleStop:728 : Transitioned guest snapshot-test to
paused state
2014-02-02 14:41:30.031+0000: 5843: debug :
qemuProcessHandleResume:776 : Transitioned guest snapshot-test out
of paused into resumed state
There are bugs here but I am not sure yet if this is libvirt
regression or engine.
I'm adding Elad and Maor since in engine logs I can't see anything
calling for live snapshot (only for snapshot) - Maor, shouldn't
live snapshot command be logged somewhere in the logs?
Is it possible that engine is calling to create snapshot and not
create live snapshot which is why the vm pauses?
Elad, if engine is not logging live snapshot anywhere I would open
a bug for engine (to print that in the logs).
Also, there is a bug in vdsm log for sdc where the below is logged
as ERROR and not INFO:
Thread-23::ERROR::2014-02-02
09:51:19,497::sdc::137::Storage.StorageDomainCache::(_findDomain)

Thread-23::ERROR::2014-02-02

looking for domain a52938f7-2cf4-4771-acb2-0c78d14999e5
If the engine was sending live snapshot or if there is no
difference in the two commands in engine side than I would open a
bug for libvirt for pausing the vm during live snapshot.

I have two CentOS 6.5 Ovirt hosts (ovirt001,
ovirt002)
I've installed the applicable qemu-kvm-rhev
packages
from this
site:
http://www.dreyou.org/ovirt/vdsm32/Packages/ on
ovirt002.
On ovirt001 if I take a live snapshot:
Snapshot 'test qemu-kvm' creation for VM
'snapshot-test' was
initiated by admin@internal.
The VM is paused
Failed to create live snapshot 'test qemu-kvm'
for VM
'snapshot-test'. VM restart is recommended.
Failed to complete snapshot 'test qemu-kvm'
creation
for VM
'snapshot-test'.
The VM is then started, and the status for the
snapshot
changes to OK.
On ovirt002 (with the packages from dreyou) I
don't
get any
messages about a snapshot failing, but my VM
is still
paused
to complete the snapshot. Is there something else
other than
the qemu-kvm-rhev packages that would enable this
functionality?
I've looked for some information on when the
packages
would be
built as required in the CentOS repos, but I
don't see
anything definitive.
http://lists.ovirt.org/pipermail/users/2013-December/019126.html
Looks like one of the maintainers is waiting for
someone to
tell him what flags need to be set.
Also, another thread here:
http://comments.gmane.org/gmane.comp.emulators.ovirt.arch/1618
same maintainer, mentioning that he hasn't seen
anything in
the bug tracker.
There is a bug here:
https://bugzilla.redhat.com/show_bug.cgi?id=1009100 that seems
to have ended in finding a way for qemu to expose
whether it
supports live snapshots, rather than figuring
out how
to get
the CentOS team the info they need to build the
packages with
the proper flags set.
I have bcc'd both dreyou (packaged the
qemu-kvm-rhev
packages
listed above) and Russ (CentOS maintainer
mentioned in the
other threads) if they wish to chime in and
perhaps
collaborate on which flags, if any, should be
set for the
qemu-kvm builds so we can get a CentOS bug report
going and
hammer this out.
Thanks everyone.
**crosses fingers and hopes for live snapshots
soon**

How would you developers, speaking for the
oVirt-community,
propose to
solve this for CentOS _now_ ?
I would imagine that the easiest way
is that
you build and
host this one
package(qemu-kvm-rhev), since you´ve
basically
already
have
the source
and recipe (since you´re already
providing it
for RHEV
anyway). Then,
once that´s in place, it´s more a
question of
where to
host the
packages, in what repository. Be it
your own,
or some
other
repo set up
for the SIG.
This is my view, how I as a user view
this issue.
I think this is a pretty valid view.
What would it take to get the correct qemu
package
hosted
in the
ovirt repo?
