Thanks for this. I've added a link on the homepage and fixed the
formatting issues for now by surrounding in <code><pre></pre></code> tags.

I went as far as recreating the HVM's boot and lvm partitions, rsyncing the ubuntu distro, patching the linux-2.6.32 kernel with latest xen pvm-hvm patches, updating the boot/grub/menu.lst for the new kernel but nothing I did seemed to work so I gave up pretty quickly. So in the mean time having a CentOS HVM image is great, thanks for creating and sharing!

I'm considering adding "ignore_exit_status=True" to this command since it's executed just to make absolutely sure that the rpc_pipefs is mounted. As you've seen this is not *always* necessary and really should be done by the portmap/NFS startup scripts.
