Updated Branches: refs/heads/master c0419791e -> accfccd83
Summary: Add support for nested hypervisors to the VmWare resource. Add a flag VmDetailConstants.NESTED_VIRTUALIZATION_FLAG Add an advanced config uption VmwareEnableNestedVirtualization Depending on the settings of the flags and the capabilities of the target hypervisor the nested virtualization option will be set on guest VMs. It's a global setting intended only for developers to support cloud-in-a-cloud deployments.
