Re: [libvirt] [PATCH 0/2] Using client-id for DHCPv6 host identification

The first patch is a trivial fix to the network schema

The second patch adds the capability to use the client id
to improve the reliability of having a system use a fixed
IPv6 address.

Trivial fix: in dhcp-host the name is optional
use client id for IPv6 DHCP host definition

When I originally submitted the patches for DHCPv6 I thought that using
the host name for specifying hosts with fixed IPv6 addresses would
work. Lots of testing proved that to be a foolish assumption. The only
thing that works is to specify the ID (Client ID). This has been
testing with DUID-LLT, DUID-LL, and DUID-UUID.
One of the most difficult parts in this was getting the patterns in the
schemas correct for the various types of DUID. I think I have tested
them sufficiently but ??? One of the more difficult things was to
handle bytes where the leading zero is suppressed.
