I have a question about a Xen host that runs dhcpd and installing guest/running guest VMs (that use DHCP)... On other hosts or hosts running VMs, they are absolutely able to get DHCP addresses no trouble... However, the fun begins when the machine I run dhcpd on is also hosting VMs. I can see in /var/log/messages the request and ack from dhcpd but the guest VM never hears it. If I should bounce dhcpd prior to a guest install or start a guest VM - everything works just fine. I'm guessing, perhaps, there is some iptables rule I need to set up? Based on the init scripts, dhcpd definitely starts before xend and xendomains and ultimately the xen bridge... Anybody know what I need to do :) I've been bouncing dhcpd in /etc/rc.local and starting any VMs there. Although annoying, I'd rather do it "right" so I can auto start my Xen guests... Thanks ahead of time! Scot P.
