[Qemu-devel] Assertion failure taking external snapshot with virtio drive + iothread

I'm running into the same problem taking an external snapshot with a virtio-blk drive with iothread, so it's not specific to virtio-scsi. Run a Linux guest on qemu master qemu-system-x86_64 -nographic -enable-kvm -monitor telnet:0.0.0.0:1234,server,nowait -m 1024 -object iothread,id=iothread1
