[Xen-users] Network bridging problem for Centos 5 Dom-O and Debian Etch
Hi,
I've been trying to get a Debian Etch Dom-U to run on a Centos 5.2 Dom-O, and it seems that the only thing that's not working is the bridged networking. I can't get *any* traffic to or from the Dom-U instance. The Centos host uses the vmlinuz-2.6.18-92.1.22.el5xen kernel and associated initrd, whereas the Debian instance uses Debian's vmlinuz-2.6.18-6-xen-amd64 image and associated initrd. In the xend-config.sxp on the Dom-O I'm using the following settings:
(network-script network-bridge)
(vif-script vif-bridge)
The output from ifconfig on the Dom-O is:
# ifconfig

To my newbie eyes these seem OK, and there seem to be packets being received from somewhere on the Dom-U. However, again on the Dom-U:
# ping 172.24.116.1
PING 172.24.116.1 (172.24.116.1) 56(84) bytes of data.

From 172.24.116.59 icmp_seq=3 Destination Host Unreachable
--- 172.24.116.1 ping statistics ---
4 packets transmitted, 0 received, +3 errors, 100% packet loss, time 3005ms, pipe 3
This is true for any remote address I try to contact.
Can anyone suggest any obvious fixes or further tests that I can run to try and correct the situation?
