How do I Change Windows server display resolution running on XenServer 8.2

[Bill Artemik]

We just installed XenServer 8.2 on new hardware. When we connect to the XenServer host and install Windows Server 2019 we are stuck with 1024x768 resolution. How do we scale this up? We have installed the Xen management tools on the VM but that hasn't made any difference.

This is how you do it in Xenserver 8.x for future me's.

 

Changing the screen resolution

To change the screen resolution of the XenCenter console on a UEFI-enabled VM:

1. Open the Windows Settings

2. Click the Update & Security button

3. Under the recovery tab, press the Restart now button.

4. Navigate to Troubleshoot > Advanced Options > UEFI firmware settings.

5. Press Restart. During restart, the UEFI settings menu loads.

6. Navigate to Device Manager > OVMF Platform Configuration. This displays the current screen resolution.

7. Press Enter to see the screen resolution options.

8. Use the arrow keys to select the desired screen resolution and press Enter.

9. Press F10 to save the changes and confirm your choice.

10. Reboot the VM to see the XenCenter console in an updated screen resolution.

Can you try this and see if it helps ?

1. Take a Snapshot of the VM.

2. xe vm-param-set uuid=<VM-UUID> platform:vga=std platform:videoram=16

And did XenTools (Management Agent) install properly ?

This worked perfectly. One note: you must shutdown the VM to get this to register. Restarting the first time did not work. But after shutting down and then starting the VM, the resolution changed! Thank you! Nice trick!
