HI Alexandru We use "Windows PV" OS type on our Windows VM's - this provides the Hyper-V enlightenments.

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!
