Re: [Xen-users] multiple vif's/bridges



ok, so, ... brctl show shows this:

xen-br0         8000.001143fd7101       no              eth0
                                                        vif10.0
                                                        vif11.0
                                                        vif12.0
                                                        vif9.0
xen-br1         8000.001143fd7102       no              eth3
                                                        vif10.1
                                                        vif11.1
                                                        vif12.1
                                                        vif9.1

so obviously the interfaces are bound to the correct bridges, i just can't reach any of the interfaces through the second bridge (eth0 isn't plugged in ...)

I know eth0 worked when it was plugged in ... so maybe there's a different issue here? i know eth3 works, i ssh in to it and it can get out ... don't know where to go from here ...

any suggestions?

everyone has been very helpful so far, thank you all, hopefully i will become knowledgeable enough to help out others.

However ... if I use the below, it DOES set up two vif's with the correct addresses, however, they can't reach/be reached by the internet. (Only eth3 (of dom0)->xen-br1 is external available, so it seems to me they aren't binding to br1, but to br0.

My reason for thinking this is 1) the no external availability and 2) in the dom0 ifconfig the vif.1 has the same MAC as br0, leading me to believe it's bound to that MAC.

"The MAC of xenU's eth0, eth1 etc. The MAC of vifX.Y in dom0 always shows
fe:ff:ff:ff:ff."

is this true? It seems vifX.1 (bound to br1) should have MAC of br1, vifX.0 bound to br0 should have MAC of br0. Maybe this is where I'm going wrong.

Everything worked fine when i was using eth0/br0 as my external interface ... so i feel like the bridge binding is my only problem ...

ugh, sorry I'm having so many problems ...

 the configuration files are actually python scripts, so the
 2nd line there is replacing the information from the first. This is
 what you actually need:

 vif = [ 'mac=aa:00:00:1a:%d:11, bridge=xen-br0' % (vmid),
        'mac=aa:00:00:1a:%d:12, bridge=xen-br1' % (vmid)]
