Hi there,
I have a problem "porting" my domU to another kernel.
I had used the Ubtuntu 6.10 generic kernel, for both dom0 and domU, but
since there was no module support I compiled my own.
dom0 is up and running again, but when I try to create the domU I get an
error (had first a special domU kernel used, but also tried the dom0
kernel. there was no difference)
root@main:~# xm cr -c /etc/xen/root.cfg
Using config file "/etc/xen/root.cfg".
Error: (22, 'Invalid argument')

In addition to this after executing the command (producing the error),
the next xen related command e.g. xm list, xentop, ... causes a system
crash.
It stops responding completly and only a hardware reset is getting it
back to life. (But there's no entry in syslog about any failure...)
