Which version of libguestfs is this? I think you'll have no hope of

getting upstream libguestfs to run on RHEL 5. There is a branch

('oldlinux') which may still work: https://github.com/libguestfs/libguestfs/commits/oldlinux

I think the EPEL 5 package is the same as this branch. In particular the EPEL 5 package has the "Add-null-vmchannel-back-for-qemu-without-virt" patch which should make it work on RHEL 5, although for some reason it doesn't. Can you post the full, unedited output from 'libguestfs-test-tool'.

When libguestfs runs qemu-kvm, it sets up a TCP socket first [on RHEL 5 -- it works differently upstream]. Without the socket existing (and sending commands etc), the qemu-kvm command on its own won't work.

User-Mode Linux is also a possibility. Slow but consistent

performance. Unfortunately it lacks several important features (notably qcow2 support). The other unfortunate thing is that we

didn't support UML in 1.20 -- it was added in 1.24. Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-builder quickly builds VMs from scratch http://libguestfs.org/virt-builder.1.html
