Windows7 VM from ProxMox 4 to ProxMox 6.0-4

Got a .raw file containing a Win7Pro image that ran fine on ProxMox 4.x Had to take care of some broken disks and decided to backup everything and replace the whole setup. Now I have a 6.0-4 with a couple Linux based VMs, so far all good. The trouble I have is with a Win7pro - It boots the win logo comes on but nothing else is happening. This VM does NOT have virtIO. Any way we can recover this image? [Alternatively we can create a win10 image but the tutorials I found so far are either for proxmox 5, or a Windows 10 version under 1903 - I need a 1903 Pro working or recover the WIN7pro.)

From the old server
root@proxmox:/etc/pve/nodes/proxmox/qemu-server# cat 203.conf
boot: cdn
bootdisk: sata0
cores: 4
memory: 6144
name: win7pro
net0: e1000=26:6F:E5:E9:C6:67,bridge=vmbr0
numa: 0
onboot: 1
ostype: win7
sata0: raid5:203/vm-203-disk-1.raw,size=50G

Found this : "Setting the OS Type to "Vista/2008" (thus disabling hv-tlbflush) could be a useful workaround for now. If that fixes it for you, let us know, as we are currently investigating this issue. It seems like it has something to do with running on older hardware especially."

and it works again :)

Does anybody has a HowTo for Win10 1903 and ProxMox 6.0-4 ? Will need that eventually.
