Re: [Xen-users] Serial port on the domU

["sven waeyenbergh" <sven.waeyenbergh@xxxxxxxxx>]

What version of xen are you using ?
i'm using 3.0.3-1-amd64 on debian and have exactly the same problem.

drivers load on domU, but do not detect any serial ports.
subsequently loading the drivers on dom0 does work (if you un-blacklist them first),
even if the domU is still running, so i thought the irq/ioports statement was simply not being picked up,
but according to xend.log, they are. no obvious errors.

my gamble is on CONFIG_XEN_DISABLE_SERIAL being set on the domU (also on dom0, but that works).
is there anyone out there that can confirm serial ports working on domU with a kernel that has the above config entry set ?

I configured a domU to access to the physical serial port of the dom0
(/dev/ttyS0) typing this in the domU configuration file:

irq = [ 4 ]
ioports = [ "3f8-3ff" ]

The domU starts without any error, but the serial port isn't recognised.
The /dev/ttyS0 device exists on the domU, and I blacklisted the
serial_core, the 8250 and 8250_pnp modules on the dom0.

What is the problem? Could you help me, please?

Thank you very much!
Bye.
