VM Performance after Template Upload

[Mevludin Blazevic]

Hi all,

some of our users have reported that after they uploaded QCOW2 templates 
to our ACS environment and started a VM from the template, the VMs ran 
very slow. In contrast, VMs installed directly in ACS using ISOs for 
example are very fast. I wonder if something in the upload view was 
misconfigured by the users.

We are using KVM and in the upload view we can choose Root disk 
controller, OS Type and other options like enabling HVM. Any ideas?

Best Regards

Mevludin
