Okay, this is probably a race condition bug. If remove:
<iothreads>1</iothreads>
and
iothread='1' from the disk which causes the command to change from:
-device virtio-blk-
pci,iothread=iothread1,scsi=off,bus=pci.0,addr=0x5,drive=drive-virtio-
disk0,id=virtio-disk0,bootindex=2,write-cache=on
to
-device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x5,drive=drive-virtio-
disk0,id=virtio-disk0,bootindex=2,write-cache=on
I don't get crashes anymore.
So for sure it has something to do with iothreads.

I get a qemu crash with:

It doesn't do it every time, but most of the time.
