Subject [jira] [Created] (CLOUDSTACK-9884) Duplicate of VR after disabling RvR

Patrick created CLOUDSTACK-9884:
-----------------------------------

             Summary: Duplicate of VR after disabling RvR
                 Key: CLOUDSTACK-9884
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9884
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Virtual Router
    Affects Versions: 4.9.2.0
         Environment: CentOS 6.8 + XenServer 6.5
            Reporter: Patrick
            Priority: Critical


Our environment is:
ACS: 4.9.2 (migrated from 4.5.2)
Management Server: CentOS 6.8
Hosts: XenServer 6.5 SP1
System VM: systemvm64template-4.6.0-xen.vhd.bz2
Network: Isolated Network
Network Offering: Offering for Isolated networks with Source Nat service enabled

Issue description:
After the migration to 4.9.2 and the multiple (known) issues with RvR, all networks had their
offerings changed to disable HA and RvR and run networks with a single VR.
Since, the following actions initiate the creation of a "duplicate" second VR, ending in an
UNKNOWN state, and triggering a lot of random network issues.
- New VM instances creation
- Clean restart of the network
Interestingly, when switching between offerings, it also recreates the VR, but it doesn't
do any duplicate this time.

Analysis:
This only impacts networks that were initially set as HA network with RvR. These networks
keep the redundant flag to 1 in the networks table, even though the offering redundant_router_service
flag is set to 0. I believe it should be changed to 0 when the network is using an non-HA
offering.
