This is what happens when I start the vm:

xm create -c Gentoo-32-test.cfg
Using config file "./Gentoo-32-test.cfg".

    pyGRUB  version 0.6
 ââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââ
 â Gentoo Linux 2.6.32-xen                                                â
 ââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââââ
