Hello Alexandru, Thanks for sharing. The reason could be that the VM is using IDE instead of virtio. Please stop the VM and add the key "rootDiskController" with value "virtio" and see the difference. You'll have to ensure that virtio drivers are installed on the VM so that it would be able to detect the disks.
Thanks, Jayanth ________________________________ From: Alexandru Stan <alexandru.s...@lifeincloud.com.INVALID> Sent: Friday, May 24, 2024 12:21:03 am To: users@cloudstack.apache.org <users@cloudstack.apache.org> Subject: RE: Windows VM performance in ACS Hi Jayanth, I don't have that key. In the settings section of the vm there are 2 keys, Message.ReservedCapacityFreed.Flag and rootdisksize. I don't have a template yet, actually this vm was installed from a Windows ISO (that is registered as Windows PV in ACS) and I was hoping to transform it into a template with cloudbase-init, but since the performance is so bad I didn't get past the updates phase...

I tried to deploy a W10 instance, with the virtio drivers, and the performance is very, very poor (for example it took almost 3 hours to install a CU, the actual setup took about 50 minutes and so on). The hypervisor kvm on a HP server, with ssd's for storage. In other apps there are those hyper-v enlightments that can be enabled for Windows guests and it really makes a difference, but I have no idea if this is a thing in ACS too. If someone has some info on this, please share. Thank you! Disclaimer *** This e-mail contains PRIVILEGED AND CONFIDENTIAL INFORMATION intended solely for the use of the addressee(s).
