Here is some more information.  I am using Ubuntu 12.04 LTS, I have turned
off apparmor.

Here is my mount: dedup:/big_pool/os-grizzly on /os-grizzly type nfs
(rw,noatime,nolock,tcp,bg,intr,hard,addr=10.54.90.10)

root@test1:/# find /os-grizzly -type d | xargs ls -l -d
drwxr-xr-x 4 root   root   4 Jun 21 13:39 /os-grizzly
drwxr-xr-x 3 glance glance 3 Jun  3 10:25 /os-grizzly/glance
drwxr-x--- 2 glance glance 4 Jun 19 15:41 /os-grizzly/glance/images
drwxr-xr-x 3 nova   nova   3 Jun 21 13:39 /os-grizzly/nova

drwxr-xr-x 2 nova   nova   6 Jun 19 15:42 /os-grizzly/nova/instances/locks

root@test1:/# grep -RE "^[^#]" /etc/libvirt/*.conf
/etc/libvirt/libvirtd.conf:listen_tls = 0
/etc/libvirt/libvirtd.conf:listen_tcp = 1
/etc/libvirt/libvirtd.conf:unix_sock_group = "libvirtd"
/etc/libvirt/libvirtd.conf:unix_sock_rw_perms = "0770"
/etc/libvirt/libvirtd.conf:auth_unix_ro = "none"
/etc/libvirt/libvirtd.conf:auth_unix_rw = "none"
/etc/libvirt/libvirtd.conf:auth_tcp = "none"
/etc/libvirt/qemu.conf:dynamic_ownership = 0


I am stumped.  It was working fine before I made the changed
(dynamic_ownership, listen_tls, listen_tcp, auth_tcp) and started up the
other compute nodes.  :/
