Re: [Xen-users] Cannot open root device

You don't need the Xen kernel in the guest's virtual disk because you specify 
it in the domain config file (the domain builder then gets it from that 
location in dom0's filesystem).

For installing random OSes, take a look at Soffi's selection of guest 
filesystem tarballs at http://www.kvadratrot.net/~xen/
