Description of problem:
SELinux is preventing qemu-kvm access to NFS filesystem when I was installing a
new system and wanted to use a DVD iso for installation, which was placed on a
NFS filesystem.

Version-Release number of selected component (if applicable):
selinux-policy-3.3.1-55.fc9

How reproducible:
Install a new machine and use a DVD iso placed on a NFS filesystem.
