Did you find anything with your investigations? This is causing me grief 
at the moment.
I have now bought a new server which supports hardware virtualisation 
and I am seeing the following results
- Note, running Fedora 19 x64. The machine was temporarily connected to 
the internet and "yum update" was run, so the packages should be up-to-date.
If I start a VM with "--paravirt"
"xl console domU" works
"virsh console domU" fails with "error: this function is not supported 
by the connection driver: virDomainOpenConsole"
If I start a VM with "--hvm"
"xl console domU" fails with "xenconsole: Could not read tty from store: 
No such file or directory"
"virsh console domU" fails with "error: this function is not supported 
by the connection driver: virDomainOpenConsole"
I am currently unable to install a domU using --hvm as I am not aware of 
any way to connect to the console.

Thanks
