Error trying to restore removable drives: Device 'drive1' is not removable

**Describe the issue**
I am trying to install x86_64 Ubuntu 20.04.3 LTS Server in a VM but am running into an issue with removable disks. When I put the removable drive first in the drive order, I get "Error trying to restore removable drives: Device 'drive1' is not removable" when trying to start the VM.

I want to use UTM to run x86_64 Ubuntu 20.04.3 as a build target. Also if this works on Big Sur (i.e. Big Sur Host, x86_64 Ubuntu Guest), I'll just run it like that until Monterey is debugged.

I also tried to put the removable drive after my VirtIO disk and SeaBIOS starts, but I get:

```
Booting from DVD/CD...
Boot failed: Could not read from CDROM (code 0003)
```

**Configuration**
* UTM Version: 2.1.2 (31)
* OS Version: macOS Monterey 12.0 Beta 5 (21A5304g)
* Intel or Apple Silicon? Apple Silicon

**Crash log**

N/A.
