-------------------------------------
Summary: [OVS] Network update from OVS to vlan does not implement the network properly
Key: CLOUDSTACK-6798
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6798
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server, Network Controller
Affects Versions: 4.4.0
Environment: Latest build from 4.4 with commit d130530bd3e1cd6d8249d5045e00e4e4e2201521
Reporter: Sanjeev N
Assignee: Murali Reddy
Priority: Critical
Fix For: 4.4.0
[OVS] Network update from OVS to vlan does not implement the network properly
Steps to Reproduce:
==============
1.Bring up CS in advanced zone with Xen cluster
2.Create physical network with GRE isolation
3.Create network offering with virtualnetworking and OVS as the connectivity service provider
4.Create one guest network with above offering
5.Deploy few vms in the above network
6.Stop all the vms and update network to default isolated network offering "Offering for Isolated networks with Source Nat service"
7.Deploy one vm in the network after network update
Result:
======
1.Network update was successful but the network is not implemented propertly. Network did not get any vlan ID. Broadcast uri for the network still remains as vs://985 instead of vlan://985.
2.So the guest vms would not get any ip addresses.
3.Network is of no use. On Xenserver cluster CS is not creating network with VLAN 985. Deploying new vms or starting the existing vms are plugging vifs to the existing tunnel bridge but tunnel ports not not getting created between the hosts since the offering does not have the OVS provider.
Following are the network details from db after network update:
