I am running a single HVM guest under the latest xen-unstable version. I get
very random kernel crashes when the HVM guest is running. Then the HVM guest
freezes and I can only destroy and restart it. Sometimes even the whole
physical box freezes and I have to reboot it.
I have attached some logs and kernel traces. Does anyone recognize a known
issue about this?
