[Xen-users] Xen not restarting after power interruption

[richardsambell <richard.sambell@xxxxxxxxxxxxxxxxxxxxx>]

Good afternoon all,

I'm by no means a linux/xen specialist and this has me completely
bamboozled!!!

legacy remote system which does firewall, dmz, routing etc. guy who built it
is long gone and his notes don't help. system has been very efficiently
running Xen on gentoo for circa 5 years. power failure caused ungraceful
shutdown - not the first outage but no problems until now. restarts and
syslog looks good to me for host kernel - after all I can remote login and
su to root. I see xenblkd running (sleeping) but nothing else to do with xen
in sight.
 
here is data that I hope might help someone enlighten me with the nub of the
problem:
 
vmlinuz-2.6.11.
 xen-2.0.6
 
tried 'xend start' from root and got:

---
Traceback (most recent call last):
 File "/usr/sbin/xend", line 27, in ?
 from xen.xend.server import SrvDaemon
 File "/usr/lib/python/xen/xend/server/SrvDaemon.py", line 35, in ?
 from xen.xend.server import SrvServer
 File "/usr/lib/python/xen/xend/server/SrvServer.py", line 28, in ?
 from twisted.web import server, static
 ImportError: No module named web
 ---

"ImportError: No module named web" - so where did it suddenly go? or is this
masking some other issue?

I've read various similar posts but all were in the context of a recent
update to xen or python or whatever.  now, I know we have made no updates,
no software changes of any kind so logically let alone technically I am up
the proverbial gum tree.
 
very grateful for any help
 
cheers
 
Richard
