regression in /dev/kvm permissions, /etc/libvirt/libvirtd.conf unreadable

[Steven Dake]

The /dev/kvm needs to be owned by root:kvm 660 but it is owned by root:root 600. CentOS sets GID to KVM and drops root permissions, so it can't access the KVM file. Further complicating matters, /etc/libvirt/libvirtd.conf cannot be read by this version of libvirt unless the permissions are 644.

    Make libvirt function on CentOS

    Recent regressions in the code base removed permission setting of
    /dev/kvm to root:kvm 660 permissions which are default for CentOS's
    version of libvirt.

    Also Libvirt must be able to read its cnofiguration file, which was
    previously 600 root:root. Now its 644 root:root so its always readable.
    This is fine, since this file doesn't contain any secret information.
