I'm running a nevada b99 guest on a nevada b99 host. The guest is configured as a dhcp client.
When I snoop in dom0 while the guest boots, I see two back-to-back DHCPREQUEST packets issued by the guest. The first of the two packets has an empty UDP checksum; otherwise they seem identical. Is this a bug?
