Interesting. > Are your domains PV or HVM? They're PV. > Can you provide the vif config for the domains?

Thanks for suggesting that, yes, there's quite a bit of output from /etc/xen/scripts/vif-bridge. I've put the log here: http://files.jessen.ch/airbus-vif10-log.txt I'm not sure, but this is what it looks like: at 11:19:41 I attempt to create a new guest, unfortunately without having changed the vifname in the config. It looks like this leaves vif10 disabled: Feb 3 11:19:43 airbus kernel: xenbr1: port 2(vif10) entered disabled state Feb 3 11:19:41 airbus root: /etc/xen/scripts/vif-bridge: Successful vif-bridge offline for vif10, bridge xenbr1. At 11:20:08 I've corrected my mistake and create the new guest with vifname=vif11. There's a bit of up and down, but vif10 remains down which I discover some time later. It is odd that an existing vif should be taken down just because I tried to create a new guest with the same vifname, but is it worth writing a bugreport for? -- Per Jessen, Zürich (-2.2°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: [email protected] To contact the owner, e-mail: [email protected]
