Prachi Damle commented on CLOUDSTACK-2159:
------------------------------------------

Fixed the DeployVirtualMachine flow to check if the affinity group processor is available. If not available, deploy VM will fail and user will be indicated with suitable error.

However for existing VMs that are stopped and started when the processor is removed by admin, we are not erroring out the start. The Start VM will proceed without following the affinity group. For this alert system should be in place to alert the user. Please reopen if this behavior does not seem reasonable.

> Anti-Affinity - When "HostAntiAffinityProcessor" plugin is not included in the deployment , deployVirtualMachine() command does not error out when passing the affiitygroupnames parameter.
> Steps to reproduce the problem:
> I had few affinity groups created.
> Then removed the "HostAntiAffinityProcessor" plugin from the management server and restarted the management server.
> Tried to deploy a Vm in one of the existing affinity groups that already exists.
> Affinity groups parameter is ignored and  Vm deployment succeeds.
> In this case , there is no indication to the user that the Affinity groups parameter that he has used was actually not being respected.
> Is it better in such cases for the API to error out indicating that HostAntiAffinityProcessor is not configured in the set up anymore.
