[Users] VM not starting up

Wed Jan 1 06:56:54 UTC 2014

the lines you added that are right before the Fpaste link are the actual lines messages from libvirt that the vm dies. This message from libvirt is then shown later as the ERROR in vdsm in the Fpaste link.

The log should contain, very close to the lines you paste, but a bit before, an xml. it should look something like what I am pasting below. Also, the line right before the xml should contain a prepareVolumePath entry:
Thread-50::DEBUG::2013-12-25 14:30:45,282::vm::3031::vm.Vm::(_run) vmId=`fdfaec39-b981-4bd7-9852-6d5ac6ce2b37`::<?xml version="1.0" encoding="utf-8"?>
...<the xml continues a bit with all the vm properties>

also - what versions of vdsm, libvirt, sanlock and qemu are you using?

Also I believe these lines right before what I pasted with Fpaste link
would be relevant.
