Hey there,

I've got the following setup:
- Windows 10 -> VmWare -> ProxMox 5.2 -> WIndows Server 2012R2

This Setup is for a test purpose only on my PC but I've planned to use this on a VPS from an external Host.
Because of this KVM is disable atm.

My Problem:
The Win2k12R2 VM is verry slow and in the Taskmanager it shows all Cores are used fully.

The Proxmox Webview shows that there is only a total CPU Usage of this VM of about 20%.

And on my windows 10 Workstation in the Console "htop" shows this usage, that corrosponds with my Workstations CPU usage.

I don't think that Proxmox is the problem at this point. Pretty sure It's me just forgetting a low of things to configure.
Thanks ahead.

for qemu to use more than 1 thread you have to use 'kvm' (no idea if this could work nested this way, i guess not)
