I'm new to this list and to Xen. I'm setting up a CentOS 5.5
paravirtualized domU using virt-manager over a bridged connection, but
I'm having a strange problem. Basically, the problem is that this domU
can't get his IP address from our dhcp server, not even while doing
the network installation process or after installed. I can manually
asign an IP address on my network range which works and I can perform
the network installation and after installation finished I can see
other hosts, connect to the internet, etc. But choosing dhcp when
configuring the network at installation time won't work, I will get an
error that couldn't get a response from the dhcp server. The same
happens after installation if I configure the network interface to use
dhcp instead of a static address.

This is the config file generated by virt-manager:

name = "centos55_base"
uuid = "e07b5490-2a1e-a5a8-a29a-28fc1d8d76a8"
maxmem = 1024
memory = 768
vcpus = 1
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
vfb = [ "type=vnc,vncunused=1,keymap=en-us" ]
disk = [ "tap:aio:/var/lib/xen/images/centos55_base.img,xvda,w" ]
vif = [ "mac=00:16:36:5c:a5:b8,bridge=xenbr0,script=vif-bridge" ]

Using full virtualization works fine, no problems using dhcp on the
same xen server where I'm creating the paravirtualized domU.

Any ideas why this could be happening?
