This is the actual problem:

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,
