I bought this machine specifically to use Proxmox on it.

CPU type, NUMA, Ballooning, Display, Machine, Controllers, Bus Device, Cache, RAM amount, CPU cores amount and even some CPU flags, but that went bad so I left all to default.Īlso slow when using RDP to the VM, but it seems a little bit faster and I mean 'a little'. I have tried a lot of settings as I said. There is no Warning notification in the Device Manager. I have the QXL installed and all VirtIO drivers as I have asked the installer software to install all of them.

It's either it runs slow or it doesn't boot at all.

I spent close to 20 hours trying countless settings, driver installs, etc. Dragging windows is slow, hovering over a dock with icons is slow, opening file managers display slowly, etc. The performance is comparable than what it was on my Proxmox test machine (10yo 2-core Laptop!). It's even worse on Linux, which is weird. I am having quite slow performance on both Windows and Linux VMs.
