xen serial port access for domu?
...only 3 were given.
Steps I followed:
1) I have xencons=off as a kernel arg for dom0, and when dom0 boots,
it finds the serial port.
2) I have blacklisted 8250, 8250_pnp and serial_core, rebooted, no
serial port under dom0
3) added the following to my domu config (domu is 32bit centos 5.2, pvm)
addirq = [ 4 ]

Using serial port from a domU
....2.1
To get /dev/ttyS0 to work under domU:
- Tell Xen to use something else for its console:
in /boot/grub/menu.lst, add "console=xvc0 xencons=xvc0" to the kernel
parameters (maybe just xencons is needed)
- Tell Xen to "show" IRQ/port to the domU:
in domU''s .cfg add
addirq = [ 4 ]
ioports = [ "3f8-3ff" ]
- Tell the domU to autoload the serial module:
create in /etc/sysconfig/modules an executable script containing
modprobe 8250
Bye!
