> When VR is restarted out-of-band by VMware HA then there is no way currently CloudStack
can reprogram PF/NAT/LB rules.
> Here is the code snippet from .//server/src/com/cloud/vm/VirtualMachineManagerImpl.java
>         if (trackExternalChange) {
>             if (serverState == State.Starting) {
>                 if (vm.getHostId() != null && vm.getHostId() != hostId) {
>                     s_logger.info("CloudStack is starting VM on host " + vm.getHostId()
+ ", but status report comes from a different host " + hostId + ", skip status sync for vm:
"
>                             + vm.getInstanceName());

>                     // we had a bug that sometimes VM may be at Running State
>                     // but host_id is null, we will cover it here.
>                     // means that when CloudStack DB lost of host information,
