Re: [Xen-users] modem on serial port in Dom0

["Javier Terceiro" <correolista@xxxxxxxxx>]

Hello,

>From the DomU you have access to the physical serial port, that is to say, with lspci it leaves to you in the DomU?

If it leaves to you in lspci, then when loading  the module your DomU to use it.

In order to give access to the DomU to a port, your watch the documentation.

What kernel do you use in DomU?, this one has support for serial port.

Hi all,

I'm using Xen (stable tarball 3.0.2). I want to connect a modem to my serial
port (ttyS0). After setting "xencons=off" in the module line of my grub, Xen
doesn't use this port itself (dmesg said nothing about ttyS0).

So I did a "modprobe parport" and a "modprobe 8250" says:
FATAL: Error inserting 8250
(/lib/modules/2.6.16-xen/kernel/drivers/serial/8250.ko): Unknown symbol in
module, or unknown parameter (see dmesg)

dmesg:
8250: Unknown symbol uart_get_baud_rate
8250: Unknown symbol uart_resume_port
8250: Unknown symbol uart_register_driver
8250: Unknown symbol uart_suspend_port
8250: Unknown symbol uart_remove_one_port
8250: Unknown symbol uart_update_timeout
8250: Unknown symbol uart_unregister_driver
8250: Unknown symbol uart_get_divisor
8250: Unknown symbol uart_match_port
8250: Unknown symbol uart_add_one_port
8250: Unknown symbol uart_write_wakeup

Did anyone have experience in this error / what went wrong?
Do I have to compile my own Xen0 kernel with serial port support?

Thanks for your help,
Holger
