Hello,
0z file showing 1 server, with dual CPU, which have total of 63,96GHz. It's
overprovised 3x. And total is 191,88GHz
3s file showing 3 servers, with dual CPU which have total of 264GHz. It's
overprovised 3x. and total is the same - 264GHz.
The different is only 1 - with 191GHz - KVM hypervisor, the next one is
with xenserver.

Re: Overprovising CPU with XenServer 6.5SP1

With release of ACS 4.3, cloudstack keeps track of previous
overprovisioning values for CPU and MEM. That is done to guarantee the
resources you initially promised when VM was deployed.
I know some people will question this decision, nevertheless, it makes
sense to others - as the feature was implemented.
In order to re-balance all existing VMs CPU over provisioning value with
new values, you need to run a sql on cloudstack mysql db.
In my experience, it would also require restart of CloudStack MS servers
for change to kick in right away.
Backup your mysql db first.
Here is an example of the SQL query one might run:
> update user_vm_details set value=2.25 where name="cpuOvercommitRatio" and vm_id in (SELECT count(id) FROM cloud.vm_instance where hypervisor_type="KVM" and state not like "Expunging" and type="User" and pod_id=13);
Note this query increases CPU OverCommit value to 2.25 on all VMs in
pod_id=13. If you want to do it zonewide replace pod_id with
data_center_id="x".
You can look up the zone id in data_center table.

Hi
cpu overprovision factor is only recalculated for vms started *after*
the factor has been changed.
The more vms you're going to stop/start, the more accurate your
calculation is getting.
Please refer to http://docs.cloudstack.apache.org/projects/cloudstack-a
dministration/en/4.8/hosts.html#over-provisioning-and-service-offering-
limits
cheers,
