I get an error while installing VM Guest (Fedora Linux) on Xen.
 
The command used to install the VM guest is "virt-install --accelerate
-p --arch x86 --ram 350 --vcpus 2 --name xvm2"
 
The error log looks like this.

Domain installation may not have been

 by running ''virsh start xvm2''; otherwise, please
 restart your installation.

What could be wrong with the installation?
 
Any help would be appreciated.
 
Thx,
