in my setup the dhcp client would run only on the kvm bridge and the
hostname as I set up for the original network interface would not get
sent to the dhcp server and would thus not land in my dns server. maybe
this is a bit of a shortcut but the bridge must in some way use the same
dhcp configuration as for the 'pif' it is replacing I think.
as far as i now, the /etc/dhclient-* files are generated when you have
the DHCP_HOSTNAME variable set in /etc/sysconfig/network-script/ifcfg-*,
so maybe I should first check for presence of the file before using
it.... but it work for me :-)
about running the dhcp client twice...
I think I've seen this happen but am not really sure. at the time I
thought that the dhcp client didn't get properly shutdown/killed by the
kvm script. the script needs to find the correct dhcp client (the one
that is running of the 'pif') and shutdown that client. maybe this fails?
hope this clarifies things
