Any issues changing machine type to q35 and BIOS to OMVF?

Hi,

i have a linux vm with the following settings:

agent: 1
balloon: 0
bootdisk: virtio0
cores: 6
cpu: host
memory: 24576
name: xxxx
net0: virtio=xxxxxx,bridge=vmbr1
numa: 0
onboot: 1
ostype: l26
scsihw: virtio-scsi-pci
smbios1: uuid=xxxxxxxxxxxx
sockets: 1
startup: order=2,up=10
virtio0: vm2:230/vm-230-disk-0.raw,size=150G
vmgenid: xxxxxxxxxxxxx

Now i'm gonna to change these settings to get GPU-Passthrough work. This means I have to use

bios: ovmf
hostpci0: 81:00,pcie=1,x-vga=1 - depends on card location
machine: q35

right? Are there expected issues while changing the machine type from i440fx to q35 and SEABIOS to UEFI?

Or can I just change this and the VM will boot as usual?

Your guest will not be able to boot AFAIK.

This means that i have to reinstall the vm?

I probably try to just change the machine type and hope UEFI isn't needed for the nvidia quadro p2000.
