[CentOS] sudo for Virtual Machine Manager

I've done everything stated in the various guidance to get a regular
user to use virt-manager (graphical Virtual Machine Manager) under
CentOS 5.4 with KVM.  Placing the user in the kvm group and changing
permissions on several files to include kvm has not worked...the user
still needs to enter the root password to use the graphical VMM.

I thought of pressing sudo into service for this task.  Anyone think
this will work?

Anyone got a better way?
