Title:
qemu instance gets paused with error: kvm run failed Bad address
Status in linux package in Ubuntu:

Bug description:
We are occasionally running into the below qemu error on our Ubuntu16
KVM hypervisors managed using Openstack, where the qemu guest instance
gets paused unexpectedly.

We also saw some swap related errors in /var/log/syslog previously:

Wondering if these swap read errors happening intermittently, cause
qemu to pause the guest instance due to memory overcommitment issues.
