→ 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
Step 4. Click on Install (next to the Guest agent tools entry)
Step 5. Click on Install
The VirtIO Guest Tools ISO will automatically mount to the VM's optical drive and any previously mounted ISOs will be ejected.
Step 6. 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 7. Double-click on virtio-win-guest-tools
Step 8. Accept license agreement and click on Next
Step 9. Leave the default selection unchanged and click on Next
Step 10. Click on Finish
Step 11. Reboot the virtual machine
Step 12. 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 13 (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.
