Subject [jira] [Commented] (CLOUDSTACK-4881) Both Running and stopped vm can be scaled up using old API changeServiceForVirtualMachine that too above host capacity
Date Sun, 05 Jan 2014 21:34:50 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-4881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13862662#comment-13862662

Nitin Mehta commented on CLOUDSTACK-4881:
-----------------------------------------

Marcus - To your question - "Who decided it was right to only allow editing the offering while
the VM was off?" -

Let me just tell you what the behavior is.

changeServiceForVirtualMachine - should change the service offering of a stopped vm and has
been in CS since 3.0.x or before. Recently there was a bug introduced where it was allowing
to change the service offering of a running vm as well. That was never intended and breaks
compatibility and tests and has been fixed with this bug. This api will be deprecated in 5.0
scaleVirtualMachine - introduced in 4.2, this should allow changing the service offering of
a running as well as stopped vm. You can use this api to edit the offering whenever you want.

If you were using changeServiceForVirtualMachine for changing the offering of a running and
stopped vm, I would say please change that and start using scaleVirtualMachine instead because
 changeServiceForVirtualMachine has been since ages only supporting editing the offering for
a stopped vm only.

> changeServiceForVirtualMachine API can be used to scale up a running vm also (It should
be effective against only stopped vm)
> More over, using this API, VM can be scaled up above host capacity (both CPU and RAM)
without any over-provisioning of resources.
