So you just installed a Debian 7 Wheezy Ganeti managed Xen cluster node and it won't start up your VM with this error:
# gnt-instance start goat.cs
Waiting for job 1277134 for vminstance ...
Job 1277134 for goat.cs has failed: Failure: command execution error:
Could not start instance: Hypervisor error: Failed to start instance goat.cs: exited with exit code 1 (Using config file "/etc/xen/goat.cs".
Error: Device 0 (vif) could not be connected. /etc/xen/scripts/vif-bridge failed; error detected.
)
If look in the log file xen-hotplug.log and see this error:
# tail /var/log/xen/xen-hotplug.log
/etc/xen/scripts/vif-bridge: line 84: setup_bridge_port: command not found
Then edit the /etc/xen/scripts/xen-network-common.sh script removing the _ (underscore) from the _setup_bridge_port command. This should fix the problem and allow you to start your VM.
