[Fedora-xen] domU crash whith auto-boot

[Guillaume Bougard]

Hello,

I think Dan is right as I had the same kind of problem earlier. I fixed
this issue by following a Dan's advice on another bug involving
performance issue. You can find the fix in a previous message on this
list:
http://www.redhat.com/archives/fedora-xen/2007-April/msg00166.html

The key is to mount /var/lib/xenstored in shared memory to limit som I/O
overhead.

Maybe it should help you too.

Regards,

Guillaume
