-drive if=virtio in vm.conf vmid.conf file

[david@theredx.com]

I am trying to get disks that use virtio.
If I use the virtio0: syntax, it seems to use a PCI device.
But I want the if=virtio option, as I am getting about 3x the speed.
Anyone know how to do this?

I want
ProxMox to create
-drive 'file=0.raw,if=virtio'
not
-device 'virtio-blk-pci,drive=drive-virtio0,id=virtio0,bus=pci.0,addr=0xa,bootindex=10' -drive 'file=0.raw,if=none,id=drive-virtio0'
