This is already possible. Stop the VM, go to Settings, change the
rootDiskController and/or dataDiskController as you please.

Hi Wei,
I think lots of users are unaware of PV OS Type to improve the
performance,
I was also facing the same problem with Windows Machine and thanks to
this thread I also got better disk performance. So instead of changing
the
OS type can ACS provide an option within the UI to change the
virtualization/driver (e.g. scsi/ide) mode in a stopped VM?

If the OS type is "Windows Server xxxx", the VM will be started with

You need to change to "Windows PV", vm will have virtio NIC and disk.
If you want better disk performance, you can try with "Other PV
Virtio-SCSI
(64-bit)", which might require some changes on your windows templates.
