Hi,

In the weekend I had trouble with netbsd / xen. Console showed following 
text and xen guestdomains where not accessible from network. Also Dom0 
not allowed ssh login, only ping worked. Finally I had to reboot machine 
from powerswitch.
I think that problem started somewhere where automated rootfilesystem 
snapshot was being made or copied to NFS.

This was in the /var/log/messages (I copied only the relevant parts):
