[Xen-devel] Interface vif(d).2> goes down directly after starting up
Hello, I''m trying to get 6 interfaces to work inside the domU''s of a xen-unstable host. Using something like: xm create -c crab-domU.cfg name=test vif=bridge=xenbr0 vif=bridge=xenbr1 vif=bridge=xenbr2 vif=bridge=xenbr3 vif=bridge=xenbr4 vif=bridge=xenbr5 When the domU is booted, only eth0 eth1 and eth2 is visible. On the dom0, same thing (vif(d).0 vif(d).1 and vif(d).2). Examining the logs gave me this interesting output: (sorted for readability) vif-bridge: online XENBUS_PATH=backend/vif/9/0 vif-bridge: Successful vif-bridge online for vif9.0, bridge xenbr0. vif-bridge: Writing backend/vif/9/0/hotplug-status connected to xenstore. vif-bridge: online XENBUS_PATH=backend/vif/9/1 vif-bridge: Successful vif-bridge online for vif9.1, bridge xenbr1. vif-bridge: Writing backend/vif/9/1/hotplug-status connected to xenstore. vif-bridge: online XENBUS_PATH=backend/vif/9/2 vif-bridge: Successful vif-bridge online for vif9.2, bridge xenbr2. vif-bridge: Writing backend/vif/9/2/hotplug-status connected to xenstore. vif-bridge: online XENBUS_PATH=backend/vif/9/3 vif-bridge: Successful vif-bridge online for vif9.3, bridge xenbr3. vif-bridge: Writing backend/vif/9/3/hotplug-status connected to xenstore. vif-bridge: offline XENBUS_PATH=backend/vif/9/3 vif-bridge: brctl delif xenbr0 vif9.3 failed vif-bridge: ifconfig vif9.3 down failed vif-bridge: Successful vif-bridge offline for vif9.3, bridge xenbr0. vif-bridge: online XENBUS_PATH=backend/vif/9/4 vif-bridge: Successful vif-bridge online for vif9.4, bridge xenbr4. vif-bridge: Writing backend/vif/9/4/hotplug-status connected to xenstore. vif-bridge: offline XENBUS_PATH=backend/vif/9/4 vif-bridge: brctl delif xenbr0 vif9.4 failed vif-bridge: ifconfig vif9.4 down failed vif-bridge: Successful vif-bridge offline for vif9.4, bridge xenbr0. vif-bridge: online XENBUS_PATH=backend/vif/9/5 vif-bridge: Successful vif-bridge online for vif9.5, bridge xenbr5. vif-bridge: Writing backend/vif/9/5/hotplug-status connected to xenstore. vif-bridge: offline XENBUS_PATH=backend/vif/9/5 vif-bridge: brctl delif xenbr0 vif9.5 failed vif-bridge: ifconfig vif9.5 down failed vif-bridge: Successful vif-bridge offline for vif9.5, bridge xenbr0. As you can see, the interface 3, 4 and 5 are brought up just like 0, 1 and 2. But for some reason, they are taken down right after that. What''s causing this? I''ve tried to backtrack the operations to see if there is something calling vif-bridge offline but I didn''t find any. Is this a bug or am I doing something wrong? Please give me a hint on how to troubleshoot this.
