Description of problem:

I have created a custom version of the Fedora 8 install CD using Revisor.  This
image fails to boot with libvirt-0.4.4-1.fc8.  When the virtual machine starts,
the process stops at the boot screen (the screen that states "to install in
graphical mode press ENTER, to install in text mode type 'linux text'", etc)
with the following error:

vesamenu.c32: attempted DOS system call

Any attempts to run the installer in both graphical and text mode fail.  A
Google search suggested that using "linux0" may fix the problem but did not do
so in this case, nor did "linux0 text".

After removing libvirt-0.4.4-1.fc8 and associated packages, and reinstalling
them with the updates repository disabled (to get the original Fedora 8 version,
libvirt-0.3.3-2.fc8), the install image works as expected.

There was some discussion of this on the Revisor-users mailing list as I
initially thought this was a Revisor issue.

Version-Release number of selected component (if applicable):

libvirt-0.4.4-1.fc8

How reproducible:

Always

Steps to Reproduce:
1. Create custom install CD with revisor (may not be necessary, I haven't tested
with standard images)
2. Attempt to install using virt-install.
  
Actual results:

Install CD image fails to boot with error 'vesamenu.c32: attempted DOS system call'

Expected results:

Successful install
