→ Applies to: Hyperion 9.x and above
To ensure optimal performance and integration for virtualized Windows workloads, it is recommended to install the VirtIO driver stack and Guest Agent Tools on Syneto Hyperion.
While the platform supports emulated devices by default (such as SATA and e1000), VirtIO enables high-performance paravirtualized drivers for disk, network, memory, and display; this reduces CPU overhead, improves I/O throughput, and enables features such as clean shutdowns, memory ballooning, IP reporting, and file system locking.
The VirtIO package, available via the official driver ISO, includes all the necessary drivers and the QEMU Guest Agent to improve communication between the guest operating system and the hypervisor.
Step 1. Login to SynetoOS GUI
Step 2. From Virtualization menu, click on Virtual machines

Step 3. Select the VM on which you want to install the Guest agent tools

Scroll down to the OS Details section until you see the Install button

Install VirtIO Driver on Windows
Step 1. Login to Windows VM and open File explorer
A CD drive labeled “virtio-win-1.x.x” should appear on the left.

Open the mounted ISO and scroll down on the right until “virtio-win-guest-tools.exe” becomes visible
Step 2. Double-click on virtio-win-guest-tools
Step 3. Accept license agreement and click on Next
Step 4. Leave the default selection unchanged and click on Next

Step 5. Click on Finish

Step 6. Reboot the virtual machine
Step 7. Check if Guest agent tools are correctly installed

With the VirtIO and Guest agent tools installed, disks and network interfaces can now be switched or added via VirtIO.
To verify functionality, open the Run tab in SynetoOS and check the Guest agent tools status in OS Details. It should show Running if configured correctly.
Step 8 (optional). Login to Windows VM and run services.msc
Check if the QEMU Guest Agent service is running
If the QEMU Guest Agent service is not running on the Windows VM, start it manually.
