    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.

    Hi,
    the problem is your config:
    with "ProxMox 5.2 -> WIndows Server 2012R2" it's work.

    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)
