The kernel is 2.6.34.7-66.fc13.x86_64
The qemu-kvm.x86_64 package is at 2:0.12.5-1.fc13
The libvirt.x86_64 package is 0.8.2-1.fc13

The Fedora 11 install crashed the system, but the XML was generated and the VM is showing in virt-manager.  I have appended that XML file from /etc/libvirt/qemu at the end of this email.

Yes. KVM capable and configured in BIOS.  It is an AMD Pnenom II X4 955 processor with 8GB of RAM.

No Console.

The host file system where the OS resides is running Ext4.  However, the system has a 3ware 9650SE-8LPML with 3 RAID 1 pairs.  So a couple of the older data volumes are Ext3, but the majority are Ext4.  The VMs are setup in their own 20GB host LVM volume, in which they use LVM, which I believe are all Ext4.

Thank you for the help.
