New subject: [PATCH V3 1/3] add an config option to disable KVM acceleration
From: Wenchao Xia <xiawenc(a)linux.vnet.ibm.com>
Since libvirt-cim doesn't handle nested KVM well now, so add this
option to manually disable KVM and fall back to qemu.

ACK on all 3 patches.
I still didn't get 3/3 - there's some filter that doesn't allow it
through our mail system.
I did do a Coverity run on the sources prior to these patches - I'll be
sending out a set of patches for things found. Nothing major, there
will be 19 patches. I wasn't able to re-run with these patches due to
some internal license server issues, but hopefully those get cleared up
soon.
