Issue: I can’t get UEFI to work with VMs at all.

CE version of AHV  on Dell 4 year old hardware - AHV and CVM operational and appear fine.

VMs appear to be OK as long as it’s using legacy bios. I can’t get UEFI to boot, black screen of X/f2.

I was going to attempt a workaround: Install using legacy and convert to UEFI but I can’t get into the VM bios?  Tried F2, DEL, F12 … every F out there and it goes straight to windows.

Does anyone have a recommendation? I can take screenshots if that helps

 

What do you want to do in the bios of the vm?? If you want to convert a legacy vm to uefi you need to use:  acli vm.update <VM_NAME> uefi_boot=true

Hi, thanks for your reply. I’m using the instructions I found here:

  • Conversion tool:

    The primary tool used for this conversion is "MBR2GPT" which is included in Windows. 

  • BIOS settings change:

    After converting the disk to GPT, you need to access your BIOS settings and change the boot mode from Legacy BIOS to UEFI. 

If you’re saying that “ acli vm.update <VM_NAME> uefi_boot=true” will essentially change the BIOS setting of the VM without having to access the BIOS, I’ll try it.


Result of  acli vm.update <VM_NAME> uefi_boot=true

 

 

Some CE installs give problems with UEFI based virtual machines. To get them working you need to add cpu passthrough via: acli vm.update  <VM_NAME> cpu_passthrough=true

 

If that doesn't work either then you can only boot the bios version of the machines unfortunately. (This is only for CE installations, commercial version will always work)

That didn’t work either. It’s still a great opportunity to learn about Nutanix and so far I’m very impressed. Thanks for your help with this.
