Hi, I have a modem on dom0 which I need to make accessible to one of my domU servers (for hylafax). ttyS0 is ok on dom0: serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A but I can''t access it on domU. I have a common kernel for dom0 and domU (2.6.16.19 xen 3.0.2) with serial port support as module. Am I missing something? Is this a xen limitation?

Is this a xen limitation?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@lists.xensource.com http://lists.xensource.com/xen-users
