             Summary: OVS: tunnel networks does not work across the XenServer 
clusers
                 Key: CLOUDSTACK-6356
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6356
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.2.0, 4.1.0, 4.3.0
            Reporter: Murali Reddy
            Assignee: Murali Reddy
             Fix For: 4.4.0, 4.3.1


In the XenServer for internal networks there is known problem (there is 
solution already used for link local networks) where bridge is not created when 
VIF is plugged in to the network. So when VM starts it fails with 
VM_REQUIRES_NETWORK exception. Solution used for link local network is to 
create temp VIF connected the internal network then plug-it to dom0 and unplug 
it. 

For OVS tunnel networks created (which are internal networks as well) similar 
problem arises where across the pool members in the clusters network is visible 
but bridge is not created. Solution is to create a temp VIF connected to the 
network plug-it to dom0 and unplug it.
