Our OpenStack installation has gained a fault
[Error: Unexpected vif_type=binding_failed]
When trying to start an instance. This has ocurred after adding a 5th Compute node to the stack. I have checked all the config files a number of times and despite them being identical to their counterparts (with the exception of the node specific items such as eth0 Ip address and eth1 Ip address) nobody is able to start instances.
When launching a new instance it appears to be spawning fine and an IP address is assigned. As soon as the error shows, the IP address is lost from the instance and the instance is un-contactable. An attempt to add a floating IP to the instance reveals that there are no "Ports" to assign to the floating IP to. This has managed to cause our entire installation to fail launching instances which is very worrying and after a large amount of searching, chencking config file I would like to ask for help on this forum.
