Router VM for Oracle VM Server in the CloudStack

Problem:
- In the CloudStack, Oracle VM Server (Hypervisor) does not support a creation of router VM.
- This is  policy in the CloudStack
- We only want to create VM which is supported by Oracle Site officially.
- But router VM is custom template from CloudStack.

The decision:
- Router VM must be installed by other hypervisor like XenServer or KVM.

Code:
File: server/src/com/cloud/network/router/VirtualNetworkApplianceManagerImpl.java
Method: findOrCreateVirtualRouters(...)

HypervisorType hyType;

                if (dest.getCluster().getHypervisorType() == HypervisorType.Ovm) {

                hyType = getAClusterToStartDomainRouterForOvm(dest.getCluster().getPodId());

                } else {

                hyType = dest.getCluster().getHypervisorType();

                }                

 

 detect proper hypervisor type

    /*

     * Ovm won't support any system. So we have to choose a partner cluster in the same pod to start domain router for us

     */

    private HypervisorType getAClusterToStartDomainRouterForOvm(long podId) {

 solution:
instead of detecting in a same pod, detect hypervisor type in a data center.
