-------------------------------------------
Summary: router fails to plug nics in KVM VLAN isolation
Key: CLOUDSTACK-5654
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5654
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: KVM
Affects Versions: 4.3.0
Reporter: Marcus Sorensen
Assignee: Marcus Sorensen
Fix For: 4.3.0
When vxlan was merged, it included getBroadcastUriFromBridge, which gets the
vlan tag from the physical interface attached to the bridge. It looks for
(\D)(\d)(\D*)(\d*). If a vxlan bridge is found (brvx), it returns the second
element of this match as the broadcast id (VNI) by calling a "toUri" method.
Otherwise, it returns the fourth element, which would be the vlan id if the
device were something like 'eth0.200'. In situations where the bridge is
untagged (eth0), however, it would throw an exception in trying to turn an
empty string into a broadcast URI, causing any subsequent router setup to be
canceled.
We need to restore the old behavior of returning empty if no vlan id exists.
