[Xen-users] access serial port in domU

[wei kin <kin2031@xxxxxxxxx>]

I am having problem when I am trying to access serial port in domU. I found a solution from the wiki.xensource.com as in the following lines:

___________________________________________________________________________

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 had to install module-init-tools

I have copied /lib/modules/2.6.11.10-xenU/modules.dep and copied the serials modules to domU

I also had to change the permissions of /dev/ttyS0 to 666

I have added the modules to /etc/modules so they load on boot

__________________________________________________________________________

 

Here are my questions:

1. In my Linux,  /etc/hotplug/blacklist is a folder and has 3 files in it, which file should I use to blacklist the serial port?

2. Where should I copy the /lib/modules/2.6.11.10-xenU/modules.dep to?

3. Can you please tell me where is the 'serial module'? And where should I copy it to?

 

Thanks a lot.
