/dev/xen/evtchn disappears, HVM fails, xen 4.0.1-1 Debian Squeeze
Hi,
(this currently also being discussed on xen-users list but no solution yet)
my
server running xen 4.0.1 and Debian Squeeze (with all the xen 4.0.1
debian packages, everything installed using aptitude) was working fine
for PV and HVM guest until an aptitude upgrade last Monday, and Ive been
spending the last couple of days trying to figure this out:
- I boot my server and as long as a stick with PV guests Im fine, if
I try to start a HVM guest, the HVM guest will not boot and
/dev/xen/evtchn disappears, and any PV guest I start now will just take
off with 100% CPU
in other words:
