Re:[Xen-users] Unstable Xen host

["Mathias Diehl" <md@xxxxxxxxxxxxx>]

Hi Jamie,

actually I can't help - except sharing your experiences. We faced the situation 
on a rather old machine with XEN2 but didn't find any solution. 

We found some threads regarding USB issues - but as we have USB disbaled that 
was no solution for us. With xen3 and new hardware everything's fine.... so far 
;-)

cheers

Mat
