Good idea @miicar I just did it without installing any sacrificial OS to the VM. You just need to create Macrium "Rescue Media" ISO. It's available in Macrium menu "Other Tasks". Then you set it as "OS Install ISO" in the VM properties. You also need to set "VirtIO Drivers ISO". You can download that in the Unraid / Settings / VM Manager Then you boot to the Macrium recovery enviroment. But it doesn't have network drivers. So if your *.mrimg backup is on the array you can't get to it. Click in the menu "Restore / View Unsupported Devices", select "virtio-win" CD Drive and click "Scan". It finds and installs network driver. Now you can browse for *.mrimg image on the network and restore it to the virtual HDD you defined for the VM. If you also needed to installed drivers for the virtual HDD, then you first refresh "Disk Image" tab so it finds your virtual HDD as available target. You basically restore the image to the VM same way as you would to the real HW.
