Hi all, I'm using Xen 4.1.4-3+deb7u1 on a Debian Wheezy 7.1 We use Openvswitch and vlan tags on all the domU vifs, so we have a "vif-openvswitch" script in /etc/xen/scripts, configured in /etc/xen/xl.conf as vifscript="/etc/xen/scripts/vif-openvswitch" Until recently everything was working fine and dandy: the domU vif configuration looks like this vif = [ 'mac=00:02:c0:a8:ce:0b,bridge=xenbr0.606' ] and the vif was correctly tagged in openvswitch and brought up. Now it's not working correctly anymore (I suspect after a dist-upgrade, but can't confirm it 100%): when creating a domU instance (xl create vm.cfg) the vm starts, and a new vifXX.Y is correctly created at dom0 level, BUT: 1 - The new vif is DOWN 2 - The new vif is not added to the xenbr0 bridge as it should 3 - The new vif is not tagged (obviously, since it's not in ovs at all) I have a maintenance script to check that all running domains have their expected vlan tags (done checking the "ovs-vsctl show" output against their config file) and when it creates the port in ovs, and I bring it up with "ip link set up" it DOES work right away. I tried to track down what's wrong for a while but I'm stuck: I even tried to put a simple "touch /tmp/tempfile" at the top of the vif-openvswitch script, and it looks like (apparently) xl is not calling it at all. No sign that the script is ever executed can be found. Does someone have some useful pointer as to where to go dig further? Web searches were pretty inconclusive, and a strace on xl only shows me that the script path IS apparently written on a control socket, but I don't know where to look for more.
