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