Xen users - Sep 2010 - device error

Hi,

Virt-install is not working when I try to provision a vm today. Err is:

--

Starting install...
Retrieving file vmlinuz...

Distro: RHEL 5.5

Any idea what is causing this? It was working several weeks back but
when I try this today I got that err.

Thanks!
Paras.

Rebooting the server to the new latest kernel fixed this issue.
