+++ This bug was initially created as a clone of Bug #670942 +++

Description of problem:
Currently kernel-rt (from MRG packages) does not work with libguestfs (i.e. libguestfs-test-tool fails (or most probably kernel-rt breaks libguestfs). libguestfs always chooses the latest available kernel, maybe it should not use any kernel-rt.

Version-Release number of selected component (if applicable):
kernel-rt-2.6.33.7-rt29.45
python-libguestfs-1.2.7-1.el5.8
libguestfs-1.2.7-1.el5.8

Thanks.

The problem is the -rt kernel is compiled without support
for any virtio (in particular virtio-net and virtio-blk).
This is not particularly surprising given the target of
-rt kernels is not virt.
