I received this error on a domU that had been running 2.4.x(standalone)
before I started running Xen with 2.6. I believe upgrading modutils made
that error go away.

Use IPTables in a domU if you want it to do its own firewalling. Use iptables
in dom0 if you want to enforce firewalling and routing rules for the other
domains. You can even use both ;-)

Think of the domains as separate machines, all connected to the dom0 "machine"
using crossover cables (on dedicated interfaces). You can do with Xen
whatever you could do with that setup.

This is also my problem. Can can anybody explain a bit more about this
'QM_MODULES' thing. The weekend is coming so plenty of time to try your
tips ;-)

TIA

If you want QM_MODULES to go away install module-init-tools that will take
care of it, as far as this... file /lib/modules/2.6.11.10-xenU/modules.dep
(No such file or directory)

well, its not there, so shut down the domU and ..

mount -o loop image.img /mount/point

cp -dpR /lib/modules/2.6.11.10-xenU /mount/point/lib/modules/

umount /mount/point

rev up the domU and have fun :)

Hope this helps.
