You need to blacklist the serial drivers from the dom0 and make sure that you don't have the hypervisor on a serial port, then just add the relevant entries in the domU config. Blacklist serial: echo "8250\n8250_pnp\nserial_core" >> /etc/hotplug/blacklist Hypervisor off the serial port: ensure that xencons=tty is on the command line for your Xen kernel, and console=vga on your hypervisor command line domU config: interrupt = [ 4 ] ioports = [ "3f8-3ff" ] - Matt _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
