Description of problem:
When starting a virtual machine, qemu reports a problem reading its associated disk image.
Version-Release number of selected component (if applicable):
RHEL6 as of 5/22/2010
Always fails. Tried multiple VMs and disks
Steps to Reproduce:
1. virsh start machine_name
qemu: could not open disk image /var/lib/libvirt/images/satellite.qcow2: Invalid argument
VM should start
This problem surfaced after I ran 'yum update' on 5/22/2010. Prior to that update, all my VMs ran just fine.
