[Xen-users] Dom0 won't come up, Fedora 9

["Martin Vuille" <martin@xxxxxxxxxxxxxxxx>]

Trying to get Xen going on Fedora 9. Xen was installed from the 
distro RPMs. Xen version is 3.2.0 and the linux-xen version is 
2.6.25.3.

Xen seems to come up fine, but the system just hangs at the 
point where booting of Dom0 should start. There is absolutely
no output from Dom0.

I configured Xen to log to a serial port and captured the output 
below. Any suggestions on how to continue debugging this are 
welcome.
