------------------------------------------------------
Summary: [VMWARE] As per the code, currently CloudStack fails to
program PF/NAT/LB rules when VR is restarted by VMWARE HA
Key: CLOUDSTACK-2562
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2562
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.2.0
Environment: commit # b3e9b2a5dc0439cad60058d693cba9d3c714af70
Reporter: venkata swamybabu budumuru
Assignee: Sateesh Chodapuneedi
Fix For: 4.2.0
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());
return null;
}
}
if (serverState == State.Running) {
try {
//
// 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,
// we will heal it with the info reported from host
//
if (vm.getHostId() == null || hostId != vm.getHostId()) {
if (s_logger.isDebugEnabled()) {
s_logger.debug("detected host change when VM " + vm
+ " is at running state, VM could be live-migrated externally from host " +
vm.getHostId() + " to host " + hostId);
}
stateTransitTo(vm,
VirtualMachine.Event.AgentReportMigrated, hostId);
}
} catch (NoTransitionException e) {
s_logger.warn(e.getMessage());
}
}
}
