The only issue is you need to manually specify the I/= O port addresses for the device, with that you should be OK. I'd be deligh= ted to help you with this if you have any difficulties.=20 -- Don Dugger "Censeo Toto nos in Kansa esse decisse." - D.

Are there any alternatives to the Xen console on serial or vga? I've got netconsole working for dom0 just to realize that Xen brings its own console drivers... So usbserial won't work and even PCI-based RS232 might not work (as seen here: http://permalink.gmane.org/gmane.comp.emulators.xen.devel/53631 ) What are the long-term plans anyway for the console? I think we'll see onboard serial disappearing more often while usb is no alternative at all (nobody would want to have it's USB bus owned by the hypervisor instead of a dom). The same goes for networking, so are there any options at all? I've seen an implementation of a syslog relay (xenlogd?) back in 2006, but having the dom0 handle the events doesn't really help if the hypervisor crashes, does it?
