Hi Mistral!
that option is absolutely fine.
If you create a VM from scratch, I mean if you’re installing the Windows VM, you can provide a CDROM with the Windows ISO, and another resource with the ISO containing the virtio-drivers. Then when you install the VM you have the drivers needed by the installer and you can browse them.
This post explains this method so you can test it: How to create Windows VM?
Cheers!
