Virtual PC 2007 & SCSI Card

Problem accessing host SCSI card

I wish to run a tape backup program from Win 2000 Prof running in virtual PC 2007 SP1 hosted by Win XP prof SP3.

The reason for this is I need to ugrade to XP from win 2000 but the tape prog will not run in XP. I have it running in XP win 2000 compatability mode which appears to work ok but Microsoft warns against using backup programs in this mode.

My problem is I cannot access the SCSI card from the virtual machine which I need as the tape drive uses the SCSI interface. Yesterday I found an entry in Microsoft support which stated to use SCSI you had to go to device manager and pick SCSI & raid controller and install the driver. That would be easy if SCSI & raid controller was listed in device manager but it is not.

I have searched EE and the internet but cannot find any information.

Can anyone help

While I'm not sufficiently familiar with virtual PC, do you have an option to add resources to the virtual machine and did you add the host's tape drive as a resource within the VirtualMachine?

I'm familiar with other virtualization technologies and one of the options when configuring the VirtualMachine is the ability to specify add resources i.e. network cards, additional drives, including a tape drive.  Not sure whether you can add the scsi card as a resource, but do not see why not.

Hi arnold,

Yes I have managed to add it as you get the standard WIn 2000/XP type options to add it to the list manually but it comes up with an error 10 and still not working as Win 2000 can't see the SCSI.

Somehow I need to a way to get it to recognise the card exists as it can see my IDE Ultra card!
Do you have an unknown device listed in device manager?  This might be the scsi card that you need to provide drivers for.
Hi arnold,

No unfortunately I do not have any unknown devices.

Some where in the Microsoft site there is some info but I cannot find it again.

I am having difficulties with both my computers. One has a failed motherboard and the other a failed operating system. The system I am using at the moment is a temporary dual boot and I appear to have lost my Internet Explorer history otherwise I might have been able to get back to the info although I think it assumed you could see the card in devices list anyway.
When you shutdown the virtual machine. Can you edit the VM settings?  Do you have an option to add resources?  This is where you need to start.  There has to be a way that you can make the hosts tape drive available to the guest.  An alternative is to do a disk to tape backup.
Add access to a host's disk from the guest and have the host system with a backup of that section of disk.  If you want an on deman backup, you would need to setup on the host system a process that monitors this location for a specific file or a change of a file upon which the process will trigger a backup.
I have looked at other virtual systems and finally found a note in Sun/Oracle Virtual Box that as yet it is not possible access expansion cards such as SCSI. This was dated Jan 2010.

So it looks like this is a non starter for the moment especially as the Sun system appears to be the most comprehensive.

I have looked at VMWare but it is expensive. My aim was to utilise my existing backup system to save the cost of having new kit. For the price of VMWare I can get external hard drives and not hav the bother of running a virtual system.

Many thanks for all of your help
