Thanks for submitting this bug and helping to make Ubuntu better.

In order to give us some more info on your system, could you please run
'apport-collect 776936'?

I wonder whether disable KSM and memballoon might help.  Could you
disable memballoon by doing

   virsh edit deluge

and deleting the lines:

       <memballoon model='virtio'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
    </memballoon>

Then disable KSM by editing /etc/default/qemu-kvm and changing

  KSM_ENABLED=1
to
  KSM_ENABLED=0

then restarting qemu-kvm:

  restart qemu-kvm

Then see if the problem still reproduces.
