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.
