What is the fastest and easiest way for me to add these Natty backports packages to test them on my affected machines? I went to the PPA you mentioned but I see a very large list of packages. I would prefer to add some repo to my apt sources list and get them that way, but I'm not 100% certain exactly what to add at this point.

The package is called linux-lts-backport-natty, and should include all
kvm fixes which are currently upstream. If that does not fix it, then
the two commits cited above in comment #16 can't fix it.
SMP Linux guests are hanging under KVM. This does not happen always,
but at least 50% of the time or so.
If I start the guests with "-smp 1" or just completely omit the "-smp"
parameter this doesn't happen.
I can also say that it doesn't seem to happen on a Nehalem-based
8-core Xeon-based machine I've tried it on, but it does happen on both
an AMD Phenom II 965 machine (the one this bug report is from) as well
as an AMD Phenom II 1090T-based machine.
I am starting the VMs from the command line, manually running qemu-kvm
with a command like the following:

Is it possible in your environment to test with the kernel package from /launchpad. net/~kernel- ppa/+archive/ ppa?

Title:
KVM SMP Linux Guests Hang
Status in “qemu-kvm” package in Ubuntu:
Confirmed
Bug description:
Binary package hint: qemu-kvm
SMP Linux guests are hanging under KVM. This does not happen always,
but at least 50% of the time or so.
If I start the guests with "-smp 1" or just completely omit the "-smp"
parameter this doesn't happen.
I can also say that it doesn't seem to happen on a Nehalem-based
8-core Xeon-based machine I've tried it on, but it does happen on both
an AMD Phenom II 965 machine (the one this bug report is from) as well
as an AMD Phenom II 1090T-based machine.
I am starting the VMs from the command line, manually running qemu-kvm
with a command like the following:
qemu- system- x86_64 -m 1024 -smp 4 -cpu host -drive /var/local/ kvm/machine. qcow2,if= virtio, cache=off, boot=on -net virtio, macaddr= 77:88:99: 12:34:56 -net tap -nographic
