Hi,


I'm (unsuccessfully) trying to pass-through a tape device, that is

connected to the host, to a kvm guest (Windows 2003). The tape device

is connected over SAS with a PCI card (aacraid).


First I tried to add the device with the following parameter

# ... -drive file=/dev/st0,if=scsi

  This leads to errors on the console and a crashes the guest after a

while.


After this, I tried to pass-through the whole PCI card (with aacraid

disabled in the host system)

# ... -pcidevice host=0a:00.0

This leads to crash in the guests BIOS state.


Therefore I tried to hot add the pci device in the monitor shell

# pci_add 0 host host=0a:00.0

At least I was able to start the machine this way. Windows did

recognise the card, but was unable to start/use it (unspecified error

-10).


Has anyone an idea how to get this to work?


-Kevin


PS: I'm using kvm-84 with the patches for OSX guest support
