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) looking for unfetched domain a52938f7-2cf4-4771-acb2-0c78d14999e5 Thread-23::ERROR::2014-02-02 09:51:19,497::sdc::154::Storage.StorageDomainCache::(_ findUnfetchedDomain) 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?
