> Key: CLOUDSTACK-4746
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4746
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Affects Versions: 4.2.0
> Reporter: Nitin Mehta
> Assignee: Prachi Damle
> Priority: Critical
> Fix For: 4.2.1
>
>
> When the host goes down. Cloudstack will stop the VM's for which HA is not
> enabled. Once cloudstack marks these VM's as stopped then the capacity of
> these VM's is moved into the reserved capacity.
> If the VM's are HA enabled then cloudstack will stop and start the VM's on
> another host. During this time the capacity of the VM's will be moved to
> reserved capacity once the VM's are stopped, But when the Vm's are being
> started cloudstack will try to calculate what will be total allocated
> capacity if the VM is started again ( even though the CPU for the VM is
> already reserved). This is a bug in cloudstack where the CPU required for the
> VM is considered twice when calculating the allocated capacity.
