I respond to myself:
Before in xen 3.0 this was okay: vif = [ 'mac=aa:dd:rr:ee:ss:11', 'mac=aa:dd:rr:ee:ss:22, bridge=xenbr1']
The first vif was implicitly attached to bridge 0 (xenbr0). BUT now in 3.1 this doesn't work anymore, you must explicitly give the "bridge=xenbr0" argument: vif = [ 'mac=aa:dd:rr:ee:ss:11, bridge=xenbr0', 'mac=aa:dd:rr:ee:ss:22, bridge=xenbr1']
beware...

Hello,
I have a big problem: Dom0 is centos5.1, domU are centos5.1. My setup is really simple, the only thing is that I give 3 nics to the domU so I use a modified network script (which has worked since january... since fedora 6): " #!/bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 "$dir/network-bridge" "$@" vifnum=1 "$dir/network-bridge" "$@" vifnum=2 "
So I have updated my xen dom0 from 3.0.3-rc5-8.1.15.el5 to 3.1.0-53.1.4.el5 (and kernel-xen 2.6.18-8.1.15.el5xen to 2.6.18-53.1.4.el5xen) and now my domU cant access the network. The interfaces are good in the domU, all seems to be ok but there are no connectivity at all (no arp entries). This message shows up on the dom0 each time I launch a domU:
blkback: ring-ref 9, event-channel 7, protocol 1 (x86_64-abi)
Do someone know what is happening ? this is very embarrassing after a simple upgrade... Hopefully I have another identical server (Centos 5.0 with 5.1 domUs) which is still in 3.0 but I cant stay not updated.
Thanks for any help.
