Thank you, Prashanth. I am attempting to create a template and I am having a time getting the NIC to be the Redhat VirtIO driver. It keeps wanting to use the E1000 NIC. I do not have any exclamation points in the device manager. All of the drivers are installed. All the other things are there such as the ballot drivers, etc. It is still using the QEMU disk, but that's because I have not changed it yet, since this is a template in creation.
I have looked through the settings in Cloudstack and do not see where I can specify this. I have tried the Windows 2022 template with Server 2022 and the 2025 template with 2025. Am I missing something in my agent.properties file or something else?

You can add qemu-guest-agent if you plan to take storage-based instance snapshots https://docs.cloudstack.apache.org/en/latest/adminguide/virtual_machines.html#storage-based-instance-snapshots-on-kvm You can skip SR-IOV driver as there is no support for SR-IOV with KVM in Cloudstack AFAIK Thanks Prashanth ________________________________ From: Marty Godsey <[email protected]> Sent: Tuesday, November 4, 2025 7:27 AM To: [email protected] <[email protected]> Subject: KVM Drivers for Windows VMs Hello, I am creating my template for KVM for Windows, and I wanted to ask about the virt drivers. I know I need to add things like the local disk drivers, balloon driver, NIC, etc. But what else should be included? Should I add the SR-IOV driver? The guest-agent? This is my first KVM cluster. I appreciate the guidance. Marty
