I think you want to do the following to patch your files:
cd /root/xen-3.0.1
patch -p1 < /path/to/wherever/you/put/the.patch
That should automatically patch the correct files (they're under
tools/python/xen/). When you're done, do the following
cd /root/xen-3.0.1/tools/
make
make install
And then restart xend however your distribution expects you to do it
(usually '/etc/init.d/xend restart').
I don't think you need the serial port IRQ sharing enabled since you
won't be sharing the IRQ with anything within your guest, but I'm not
100% sure what that option does. If it doesn't work one way, I guess try
it the other.
