I have not tried rebooting; always stopped and restarted the qemu instance. Will try on the next occasion. Before I wrote that I tested on kvm-83 and 84 but it turns out the kvm-84 part was wrong: Since the upgrade 4 days ago I have not yet had a hang. I noticed that you Tomasz are also running kvm-83. Maybe kvm-84 fixed the issue already?
