Hi everybody, this is my first post. Trying to pull this one off for 2 days..
So i have a proxmox (6.2-14) installed in a debian 9 installation that is running on a VPS. (Contabo)
This confoguration doesnt allow to use hardware virtualisation (so no KVM harware virtylisation = yes possible)
I want to install a guest Windows 10 or Windows Server to run a windows application in cloud.
I followed 4 posts on this topic, this one beeing the most complete: https://davejansen.com/recommended-settings-windows-10-2016-2018-2019-vm-proxmox/

But to no avail. The guest crashes always somewhere during the installation. I tried almost all possible configurations that made a bit sense and offcourse i tried the offical guide multiple times. Is it even possible to run windows inside this setup?

So basicly:
Contabo VPS
---Debian 9- Proxmox 6.2
------Windows 10/Windows server
 
Do you have other stuff running there currently? Proxmox VE uses Debian 10 as base, not 9.

Generally, it is possible to start Windows 10 without KVM hardware virtualization. However, it's not fun to use. One example configuration that should work:
Code:
➜  ~ sudo qm config 900
agent: 1
bootdisk: scsi0
cores: 2
kvm: 0
memory: 4096
name: windows10a.example.com
net0: virtio=DE:19:1E:08:28:1A,bridge=vmbr1
numa: 0
ostype: win10
scsi0: nvmeThin:vm-900-disk-0,cache=unsafe,size=100G
scsihw: virtio-scsi-pci
sockets: 1
vga: qxl
smbios1: uuid=38f45de3-a6b2-4466-8f26-dd7c8628ec18
vmgenid: 48c76b2f-6568-4700-88df-842293609d9e
