Are you sure you had those blanks in there after the dashes and around
the equals sign? The dashes should be double slashes anyway.

This should more look like this:

#sudo xen-create-image --hostname=xen2.ivanvictor.com --force

Interesting. Which kernel version in the DomU? And which on the Dom0?

Should usually be /dev/xvda2 or so. /dev/sda2 is said to no more work
with current kernels.

This looks like Ubuntu 10.10 Maverick which (if I remember correctly)
has 2.3.36 kernels. If you use pygrub and kernels from the DomU, it's
very likely that /dev/sda2 doesn't work.

If that information doesn't help so far, please post your DomU config
file (/etc/xen/xen2.ivanvictor.com.cfg or so) and we probably can tell
you what needs to be changed.

BTW, which version of xen-tools do you use? (Ubuntu still hasn't
included xen-tools again.)

		Kind regards, Axel
