As mentioned before, I disabled xen before the etch->lenny upgrade. Now I’ve re-enabled xen, and the following bits may be of wider interest:<\/p>\n

My server at the Hetzner hosting center<\/a> has one static IP address and a small network that is routed towards that IP address. So my plan was to use this small network (88.198.160.176\/28) for the virtual switch inside the xen Dom0 and connect all the domUs to it. I solved this the following way:<\/p>\n

In \/etc\/network\/interfaces I tell Debian to create the bridge and use br0 as the interface of the dom0 into that bridge:<\/p>\n

\n
auto br0\niface br0 inet static\n        pre-up brctl addbr br0\n        address 88.198.160.177\n        netmask 255.255.255.248\n        bridge_fd 0\n        bridge_hello 0\n        bridge_stp off<\/pre>\n<\/blockquote>\n
That way, the xen scripts themselves have little to do. The settings in \/etc\/xen\/xend-config.sxp are:<\/p>\n
\n
(vif-script 'vif-bridge bridge=br0')\n(network-script network-route)<\/pre>\n<\/blockquote>\n
In the config-file for each individual domU, I just use something like<\/p>\n
\n
vif  = [ 'ip=88.198.160.178,mac=00:16:3e:77:e2:79,bridge=br0' ]<\/pre>\n<\/blockquote>\n
but I’m not sure whether that’s actually needed at this point.<\/p>\n
Concerning the domUs: The hints in the Debian Wiki<\/a> were helpful, especially about changes to the console handling.<\/p>\n","protected":false},"excerpt":{"rendered":"
