I don't have a way to send commands here, since the appliance runs
completely captive.
However attached are:
- the libvirt XML
- the qemu command line
which may help to reproduce the bug. I'm using upstream qemu + 91
patches provided by Tom, as detailed earlier in this thread.

I tried it with: 768 MB, 2048 MB and 20480 MB. All failed in the same
way.
