I am trying to get OpenVMS to run on Proxmox using virtio scsi and network devices. Since OpenVMS only supports the modern (version 1) virtio interface, and not the legacy (version 0.x) interface, these need to present the virtio modern interface. On most other qemu-based hypervisors, this means that I need to add ",disable-modern=off,disable-legacy=on" to the device lines for those controllers. Is there a way to do this in Proxmox?
 
You may try adding kvm options of your choice by using qm set <vmid> args=<your-args-for-qemu/kvm>.

Your options will be appended to the commandline that is used to start up the kvm vm.
