kernel-2.6.32-131.17.1.el6.x86_64 (after update and currently)
After update:
qemu-kvm-0.12.1.2-2.160.el6_1.8.x86_64
After downgrade:
qemu-kvm-0.12.1.2-2.113.el6_0.8.x86_64
Prior to installing the CR repo the host was up to date with the CentOS base and updates repos (not many packages different from the release ISO). After, it was up to date with the CR repo and the VM would not start. The host is now up to date with the CR repo except that libvirt* pyton-libvirt and qemu-kvm have all been downgraded to what was up to date for the CentOS base and updates repos.
By "won't boot" I mean that "running" a VM via virt-manager showed only a black screen with the CPU usage graphic in virt-manager at a steady state. No error messages, only a black screen.
If no one else has seen this I will look to the cent-virt mailing list as suggested. I am assuming however, that this is a CR repo issue.
