[virt-tools-list] Problem setting UUID in libvirtd.conf



I ran into a problem where the system UUID for my nodes are identical
(thanks, Tyan!). This blocked live migration, but I found a thread from
last summer saying to overcome this issue using generating a new UUID
using uuidgen and setting it using 'host_uuid' in libvirtd.conf. I've
tried this, but without luck.

[root an-node01 ~]# virsh sysinfo | grep uuid
    <entry name='uuid'>03000200-0400-0500-0006-000700080009</entry>

[root an-node01 ~]# diff -u /etc/libvirt/libvirtd.conf.orig

Any tips?
