Public bug reported:
On a Trusty KVM host one of the guest VMs shut down without any user
interaction. The system is running:

2016-12-22 09:49:49.392+0000: shutting down
In /var/lib/libvirt/libvirtd.log we see:
2016-12-22 09:49:49.298+0000: 6946: error : qemuMonitorIO:656 : internal
error: End of file from monitor
We investigated to see if this is a known issue and came across a bug
report for Fedora (https://bugzilla.redhat.com/show_bug.cgi?id=1147398),
but nothing references changes upstream that fix this.
The guest OS is Ubuntu Precise (12.04.5) running kernel linux-
image-3.2.0-101-virtual 3.2.0-101.141. There wasn't any significant load
(CPU or IO) on the guest at the time that it shut down and there wasn't
any appreciable disk IO on the KVM host either. The disks for the guest
are on the KVM host box.

Please do not report distribution specific bugs (since you're using
qemu-kvm 2.0.0+dfsg-2ubuntu1.27) against the QEMU project bugtracker -
use the distribution's bugtracker instead.
** Project changed: qemu => qemu (Ubuntu)
