Hi,
Host: CentOS 5.5
Guest: Ubuntu maverick
I am having a horrid time trying to create a guest on my xen machine.
I have tried several method. The method that I have had the most
success with is `xm create`. The problem I have is that once the I
have run:
xm create -c myconfig.cfg install=true
install-mirror=http://mirror.bytemark.co.uk/ubuntu/
install-suite=maverick
and go all the way throught the installation, the guest does not
appear in `xm list`. It appears in the list during the installation
but once the install is complete and I reboot, it never comes back. If
I try to start it with `xm create myconfig.cfg`
