[ cc'ing to -scsi because somebody there might have some insight into the
behavior I'm seeing from VMware ]

OK, I have nailed down some behavior that I saw last night after having success
in installing the VMware tools, etc.

I am currently using a SCSI CD-ROM (cd0) as the /dev/cdrom device (link to
/dev/cd0c) for VMware's emulated ATAPI CD-ROM.

Everything works wonderfully if I "power on" the virtual machine with a disc
sitting in the CD-ROM. However, if the tray is empty then VMware comes back
with a dialog box saying

  CDROM: Unable to open '/dev/cdrom'
  Device not configured

  Error connecting the CDROM device.

           (another dialog box)

  Device ide1:0 will start disconnected

This smacks of the "troubles" one might have when installing from SCSI CD-ROM
if you don't boot with a disc in the drive (sysinstall can't find the drive
when you choose CDROM as the media type if there wasn't a disc in the drive
during boot).

Is this something we can work-around in our vmmon module or is this an
unavoidable CAM thing? Do other people using SCSI CD-ROM's notice the same
thing? 

For now, I will happily insert any ol' disc into the machine as I power up the
VM, but just wondering how this can be fixed in software ultimately (or if it's
just a "VMware thing + scsi" thing and we're stuck with it).

Thanks,

-Jr
