windows 2008 guest, uefi, install iso doesn't boot

[mouk]

Hi!

I'm trying to virtualise a windows 2008 x64 server running on uefi hardware into proxmox. A created a system backup using the windows backup application. Now trying to restore that backup in proxmox, using the windows installation media. That's where things stop working...

Created a VM, OVMF bios, added a ide harddisk, the windows x64 iso to boot from, however... it cannot get into the windows installer. Getting a blank screen after the "windows is loading files..." completes.

I have tested the windows 2008 installer dvd using SeaBIOS (this works) and also checked VMF boot with a windows 2012 installer dvd (this also works).

Therefore: are there knows issues with windows 2008 / OVMF in proxmox? The rest of the settings are pretty default: intel e1000 nic, tried various graphic card settings (only not spice, since I'm not sure what linux client to use to view it), tried ide, sata, scsi, etc.

I also tried restoring my backup using the windows 2012 installer dvd, but it politely tells me to use a windows 2008 x64 dvd to restore this backup. :-(

Any pointers or ideas?

Some more observations:
* the windows 2008 R2 iso boots a bit further (passing the "windows is loading files" into "starting windows", but then a blank screen again)
* installed virt-viewer to get spice viewer access: same result

Ideas?

Anyone?

What do I have to do to make proxmox (4.2-15/6669ad2c) boot windows 2008 installation cdroms with UEFI?

Hi,
I found a bugreport here:

Seem that hyper_v enlightments are not working windows win2008 & uefi

I'll make a patch to disable hyperv enlightments in this case

Ah super!! Interesting info, your reply here is _very_ appreciated!

Any idea when this patch would become included in proxmox? Of is there a a way to disable those "hyper_v enlightments" for this specific machine in it's machine-id.conf config file on proxmox?
