[Xen-users] Opensolaris domU unable to get dhcp lease

[Michael Ralston <michael@xxxxxxxxxxxxx>]

I'm running a ubuntu 9.04 64 bit dom0 with kernel 2.6.29.6 and xen
3.4.0. My eth0 is bridged to br0 and to my guest VMs. The dom0 is
running a dhcp server on br0 which is able to provide leases to
physical machines on eth0, and also to a windows xp domU which is
bridged to br0. However my open solaris 2009.6 domU is unable to
obtain a dhcp lease.

On the opensolaris side I can see this:
michael@opensolaris:~$ pfexec ifconfig xnf0 dhcp start
ifconfig: xnf0: wait timed out, operation still pending...

With tcpdump I can see the dhcp request coming in br0, but no dhcp
offer going back out.

In the syslog of my dom0 I can see this when the opensolaris domU
requests a lease:
==> syslog <==
Jul 19 15:20:03 allendale dhcpd: 19 bad udp checksums in 37 packets


This also occurs with xen 3.3.0

Anyone had a similar problem? Any ideas what could be causing this?
