Comment 10 for bug 1652011

We see this in upstream openstack CI testing, viewable here:

This was the domain log:

I noticed this:

char device redirected to /dev/pts/1 (label charserial1)
qemu-system-x86_64: /build/qemu-5LgLIn/qemu-2.0.0+dfsg/block.c:3491: bdrv_error_action: Assertion `error >= 0' failed.
2015-11-30 18:20:18.168+0000: shutting down

This is a volume-backed VM. I think around the time that this fails, we should be trying to plug a virtual interface.

Possibly also helpful:
