Windows Server 2016 BSOD

[onebox]

Hello,

I struggle with a Windows Server 2016 VM. For performance purposes i wanted to change the CPU type from qemu64 to Host.
On the Proxmox1 Host i get a BSOD with the message "Kmode Exception not handled", so i tried to install a fresh OS but even fresh installed the same error occurs.
On the Proxmox2 the VM boots without problems.

Both Hosts are up to date but somehow have different Kernelversions.
Any Ideas on how to solve the issue ?

The Host specs:

Server Proxmox 1​

Dell R720
CPU(s) 32 x Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz (2 Sockets)

you can try upgrading the kernel version and see if the issue persists

you could just do apt update && apt dist-upgrade
.
note that after upgrading the kernel you will need to reboot the host.
