[Xen-users] DHCP in dom0

["Peter Gavin" <pgavin@xxxxxxxxx>]

Hello,

I've just started playing with xen, and I'm having trouble getting
networking going on a server I'm trying to set up.

I've just done a clean install of CentOS 4 on the server, and
installed Xen 3.0.3.0 from the rpms provided on the web page.   I'm
able to get the dom0 to boot up, but I haven't been able to get it to
grab an IP address via dhcp.  The server isn't going to be using DHCP
once its completely set up, but for now, I need it.  And in any case,
we've been toying around with using xen on all the machines we have in
a computer lab (Core 2 Duos), running Linux and Windows in separate
domUs, so we can use spare CPU time for large computations, etc. on
the Linux domU.  For this, I'm definitely going to want to use DHCP
for the dom0's IP.

Now, I've read that the xen initscript is supposed to move the MAC &
IP addresses from eth0 to peth0, but it doesn't appear that that is
happening.  Instead, eth0 has no IP address, and peth0 has
FE:FF:FF:FF:FF:FF for its MAC address.

I've spent the last hour googling for a solution, but the closest I've
found is a mention that dom0 "should" use a static IP -- but no reason
*why* it should.  Is what I'm asking for feasible?

Thanks in advance,
Peter Gavin
