I'm using cobbler on a VMware ESX server.
For now, I'm creating VMs by hand using the vmware gui client.
When I power them up they PXE boot, I type menu and choose a profile.
Was hoping I could nail down the ip to the mac in %post
I have been reluctant to manually dig into PM to find mac
address and manually make a dhcp reservation.
This wouldn't be required to pick the MAC and avoid the menu altogether.
All that requires is a cobbler system entry for the new machine
with the right mac addr and profile assignment. This creates an entry
in /tftpboot that the machine would find.
Though maybe I'm misunderstanding the problem...
I'm looking into the VMperl API. VMware is calling it a legacy API.
Don't know how much longer they will support it.
I think it won't be too difficult to use VMperl to create scripts to
make an appropriate dhcp reservations, or create a VM to order.
Will let you know when I have something more concrete than plans.
Excellent.
There's a new VI Perl SDK Beta. Haven't looked at the .exe
I downloaded. Haven't found a Linux version.
Hopefully that is just an installer and it's all web services driven.
AFAIK, VMware is supposed
to have a WSDL interface. SOAP isn't as clean (or simple) as XMLRPC,
but it'll work better
than nothing :)
Have a vague recollection of a version issue with dnsmasq
on my platform, CentOS5, but that could be my imagination,
need to look at this again.

DHCP reservations work exceedingly well. If you have manage_dhcp
turned on in your /var/lib/cobbler/settings it will write your
dhcp.conf
for you.
dnsmasq works even better as you can also pin the hostname from
cobbler
(dnsmasq does both DHCP and DNS, and cobbler can auto-configure it).
Example:
vi /var/lib/cobbler/settings
manage_dhcp : 1
manage_dhcp_mode : dnsmasq
# cobbler system add --name=foo --mac=AA:BB:CC:DD:EE:FF
--ip=192.168.1.50 <http://192.168.1.50> --hostname="
foo.example.com <http://foo.example.com>"
This will ensure that when MAC address AA:BB:CC:DD:EE:FF boots it will
automatically get the designed IP and (if using dnsmasq) the given
hostname.
if you leave manage_dhcp mode to "isc" (the default), you still
get the
variable $hostname accessible in your kickstart templates, so you can
still set hostname/etc, but you will
have other hoops to jump through to make it actually use it.
Which is
what I think you are alluding to below:

Possibly including...
(A) just-once-single-command-authorized-root-ssh (kind of scary)
(B) CGI script (still scary)
???
Both of which pose interesting security issues. DHCP
reservations are
the way to go, IMHO, because they can be done entirely server side --
but I'm not a network administrator and you might have valid
reasons for
not doing things that way.
