I finally decided to install the CR repo on one of my CentOS 6 machines that I use as a host for some VMs (also running CentOS 6). Before updating the host I updated a VM that was not critical to test the process and was able to boot that VM, so I went ahead with updating the host and the two VMs that were in use. When I rebooted the host none of the VM would start. Once I figured out that it had to be the host I started downgrading the virtual packages. I was finally able to get the VMs to boot after dwongrading qemu-kvm. Has anyone else seen this? Emmett
