Hello Bastian > > Please compile serial driver serial8250 as module instead into the kernel. > > Please explain why. I would like to provide a DomU serial port access according to the xen-wiki. To have access to the serial port in DomU, we need to prevent Dom0 from taken hold of this piece of hardware add to /etc/hotplug/blacklist the following modules to exclude from being loaded 8250 8250_pnp serial_core
domU config: irq = [ 4 ] ioports = [ "3f8-3ff" ] to load the modules in domU.
I tried without unload the 8250 driver and starting the domU resuted in an IRQ 4 error.
Kind regards
