Sorry for the confusion.<br>
<br>
I attempted to take a live snapshot of a running VM. After that failed, I migrated the VM to another host, and attempted the live snapshot again without success, eliminating a single host as the cause of failure.<br>
<br>
Ovirt is 3.3.4, storage domain is gluster 3.4.2.1, OS is CentOS 6.5.<br>
<br>
Package versions:<br>
libvirt-0.10.2-29.el6_5.5.x86_<u></u>64<br>
libvirt-lock-sanlock-0.10.2-<u></u>29.el6_5.5.x86_64<br>
qemu-img-rhev-0.12.1.2-2.415.<u></u>el6.nux.3.x86_64<br>
qemu-kvm-rhev-0.12.1.2-2.415.<u></u>el6.nux.3.x86_64<br>
qemu-kvm-rhev-tools-0.12.1.2-<u></u>2.415.el6.nux.3.x86_64<br>
vdsm-4.13.3-4.el6.x86_64<br>
vdsm-gluster-4.13.3-4.el6.<u></u>noarch<br>
<br>
<br>
I made another live snapshot attempt at 10:21 EST today, full vdsm.log attached, and a truncated engine.log.<br>
<br>
Thanks,<br>

please explain the flow of what you are trying to do, are you<br>
trying to live migrate the disk (from one storage to another), are<br>
you trying to migrate the vm and after vm migration is finished<br>
you try to take a live snapshot of the vm? or are you trying to<br>
take a live snapshot of the vm during a vm migration from host1 to<br>
host2?<br>
<br>
Please attach full vdsm logs from any host you are using (if you<br>
are trying to migrate the vm from host1 to host2) + please attach<br>
engine log.<br>
<br>
Also, what is the vdsm, libvirt and qemu versions, what ovirt<br>
version are you using and what is the storage you are using?<br>
<br>
Thanks,<br>
