Hi

I'm attaching 12 drives as raw devices to a virtual SCSI controller. When attaching them, VirtualBox will just add them sequentially, so that - including my virtual .vdi system boot drive - it's using ports 0 through 12 by default.

However, when I boot into my Ubuntu Server guest OS, only 11 of the raw disks show up. The one attached to SCSI 0:7 is gone. If I avoid port 7 altogether, and leave it unused instead using ports 0 through 6 and 8 through 13, all drives show up as expected.

I've never used a real physical SCSI device, so I don't know if this is expected? As in, it's a reserved port or something like that.

Any insight on this?

On metal the SCSI ID for the host adapter is 7, so it stands to reason that you should not use it in the chain.

Good to know, thanks!

Gonna report it as a bug, then.
