[Bug 795717] Re: 32bit rhel and centos 5.(5|6) hangs on boot on natty

[nutznboltz]

I build a 32-bit RHEL 5 compatible Qemu/KVM guest, really Scientific
Linux 5.7.  The guest was built from SL.57.090911.DVD.i386.disc1.iso
plus today's updates.

The guest runs fine with 1 CPU defined and hangs trying to boot with 2
CPUs defined so I can reproduce this 100% with the following VM host:

$ lsb_release -ds
Ubuntu 10.04.3 LTS
$ uname -srvm
Linux 2.6.38-12-server #51~lucid1-Ubuntu SMP Thu Sep 29 20:09:53 UTC 2011 x86_64

Qemu/KVM/Libvirt is the one from Natty backported to Lucid via PPA:

When the 2.6.38-12 backport kernel plus the kvm clock patch finishes
compiling I will install it and test to see if the 32-bit RHELish guest
still hangs or not.

I will also test on regular x86_64 Natty soon.
