Right, I was trying to find out how I would actually create that
image first, but if I just use virsh save for that, then the restore
via stdin does not have the same effect as virsh restore:

khyber:~|master|% LC_ALL=C PATH=/home/madduck/.bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games HOME=/home/madduck USER=madduck LOGNAME=madduck TMPDIR=/home/madduck/.tmp /usr/bin/kvm -S -M pc -m 512 -smp 1 -name lotus.madduck.net -uuid 0340c11e-0894-4dc8-a52b-90c8bf432b2b -monitor pty -boot cd -drive file=/root/grub-rescue/grub-rescue.iso,if=ide,media=cdrom,index=2 -drive file=/home/madduck/lotus.madduck.net/disk.vda,if=virtio,index=0,boot=on -drive file=/home/madduck/lotus.madduck.net/disk.vdb,if=virtio,index=1 -net nic,macaddr=52:54:00:fc:03:d7,vlan=0,model=virtio -net tap,ifname=lotus,script=/bin/true,vlan=0 -serial pty -serial unix:/home/madduck/lotus.madduck.net/ttyS1,server,nowait -parallel none -usb -vnc 127.0.0.1:0 -incoming exec:cat < lotus.save 
char device redirected to /dev/pts/0

qemu_popen: returning result of qemu_fopen_ops
load of migration failed
cat: write error: Broken pipe

Then it just sits there forever and the guest is not restarted.
