No alert in web ui, I restarted the VM yesterday just in case, no change. I also restored an earlier snapshot and tried to re-snapshot, same result. *Steve * On Tue, Apr 22, 2014 at 10:57 AM, Dafna Ron <dron@redhat.com> wrote:

from that you see the actual failure:

do you have any alert in the webadmin to restart the vm?

Sorry for the confusion.
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.
Ovirt is 3.3.4, storage domain is gluster 3.4.2.1, OS is CentOS 6.5.
Package versions: libvirt-0.10.2-29.el6_5.5.x86_64 libvirt-lock-sanlock-0.10.2-29.el6_5.5.x86_64 qemu-img-rhev-0.12.1.2-2.415.el6.nux.3.x86_64 qemu-kvm-rhev-0.12.1.2-2.415.el6.nux.3.x86_64 qemu-kvm-rhev-tools-0.12.1.2-2.415.el6.nux.3.x86_64 vdsm-4.13.3-4.el6.x86_64 vdsm-gluster-4.13.3-4.el6.noarch
I made another live snapshot attempt at 10:21 EST today, full vdsm.log attached, and a truncated engine.log.
Thanks,

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

A bit more of the vdsm log is attached.
Other vm's are snapshotting without issue.
Any help appreciated,
