Hello, I am experiencing a very slow Windows 10 VM on Proxmox 8.1. Proxmox 8.2 would NOT install on my Dell R610 dues to some undocumented bug.
Dell R610, 24 cores, 96 GB RAM
Proxmox 8.1
Click on task manger or file Windows Explorer, it pops up 10 seconds later, very unresponsive, but not graphically laggy.
I am using nested virtualization, as this is a requirement. I am also using the following settings:
VM CPU set to "Host"
benchmarks look good on CPU = 10-25%, RAM = 4/16 GB
No passthrough GPU, but graphics are not my concern here
local Gbit network, not an RDP or bandwidth issue
SCSI Controller, but the disk is on (ide0)
When i try a SCSI disk for the Windows host I'm not sure which driver to load, so I left default ied0
VirtIO = SCSI Controller, Network card,
virtio-win-0.1.262 mounted and installed
Any ideas are greatly appreciated!!
Can you point me to an optimal setup?
Thanks!!
OK Folks - I have a solution to my Windows VM slowness:
Download the VirtIO Drivers ISO from Fedora
virtio-win.iso
Mount this ISO when installing your VM
Install hard drive as VirtIO
I did not have luck with Win10 and the SCSI drivers
Use virtIO for disk and network
You will not have network until you install the EXE from fedora into the OS
After you run the "virtio-win-gt-x64.exe" you will see the virtIO network adapter connect
Use "Host" for CPU type
Ensure "KVM hardware virtualization" is enabled in the VM options
Nested virtualization will slow down the VM, but it's not as bad as without these settings.
I hope this helps someone!

Where is the nested virtualization ?
Where is the nested virtualization ?
On my Windows 10 Pro VM that is running WSL 2 and Docker Desktop. It's a little slow, I am considering moving to a Dell R720 with a newer CPU architecture to see if this is better.
