Subject Re: Dynamic Scalable Template issue

Thanks.

Just funny that on CCP 4.3 it wasn’t an issue and only after upgrading to 4.3.0.2 and a
host reboot did it change my instances.

This issue is that the instance below is a SQL server. As Windows see 32GB, it shows the used
RAM in windows as 31.6GB. The Server only has 8GB. That is what really is the issue. Causing
slowness for my users.

I have set ‘enable.dynamic.scale.vm’  to false and restarted cloudstack-management. I
will reboot an instance that is out of prod and let you know the results.
