[Xen-users] Re: how to get a scsi tape device to work with xen 3.3.1

I tried the pciback method but the domU (seabass) still doesn't show
the SCSI card above under lspci .

####

virt4:/etc/rc.local :

modprobe pciback
SLOT=0000:01:01.0
# Unbind a PCI scsi card from its driver
echo -n $SLOT > /sys/bus/pci/drivers/aic7xxx/unbind
# Add a new slot to the PCI Backend's list
echo -n $SLOT > /sys/bus/pci/drivers/pciback/new_slot
# Now that the backend is watching for the slot, bind to it
echo -n $SLOT > /sys/bus/pci/drivers/pciback/bind
xm create PCI=${SLOT} /etc/xen/seabass

####

virt4:/etc/modprobe.conf:

options pciback hide=(0000:01:01.0)
#this didn't really work to load pciback
#install aic7xxx /sbin/modprobe pciback ; /sbin/modprobe --first-time
--ignore-install aic7xxx
#
alias eth0 tg3
alias eth1 tg3
alias scsi_hostadapter aic7xxx
alias scsi_hostadapter1 cciss

Here's the log from virt4:/var/log/xen/xend.log :
