[Xen-users] Fedora 8 and pciback not showing in guest

[Simon Dean <sjdean@xxxxxxxxxxxxxxxx>]

Howdy,

Apologies if this comes up twice, I subscribed to Nabble before 
subscribing to the list and I think I may have broken something. Well 
here goes.
Im looking to virtualise three servers into one. Save space, power and 
heat.
I still havent decided which route Im going down.

I started off with Fed 9 x64 and wanting to use OpenVZ but that failed 
at every opportunity. I tried KVM/Qemu but that failed with reading the 
ISO.
I downgraded the host to Fed 8 i386 and everything started to work 
again. OpenVZ was installable and bootable, *Xen* kernel became 
bootable, and Qemu would read my ISO.
With further problems with OpenVZ basically almost being unable to do 
anything unless you're using really dated software, I decided to go with 
*Xen*.
Got my *Smoothwall* guest installed and virtually configured. Get my 
main server installed. Note, Im using all image files because I didn't 
think ahead and make any partitions for this.
So then to my Asterisk system.

Installed using the same Fedora 8 disk. But it can't see my *pci* card. 
So after a bit of googling and frustration getting *pciback* settings 
recognised by grub and the boot process, so I resort to modifying 
rc.local which sure enough captures the *PCI* device by the *pciback* 
driver:
modprobe *pciback*
sleep 2
SLOT=0000:01:08.0

# 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
#
/etc/init.d/*xendomains* start
/etc/init.d/*xend* start


But on booting my vanilla Fedora Core 8 i386 guest, it doesn't see the 
*pci* device through lspci.
I even added the following in to my 
/var/lib/*xend*/devices/xxxxx/config.sxp:
   (device
       ((uuid 04940a29-37fa-5441-2dd3-d824bc56f24d)
           (dev (slot 0x08) (bus 0x01) (domain 0x0000) (func 0x0))
       )
   )

I even wondered about what I read elsewhere about needing a frontend 
driver, so I thought I'd install kernel-*xen* via yum and it completely 
kills my image! I can't even restore with virsh. I can't remember the 
exact error, but just the generic error about failed to restore.
Im about ready to throw in the towel on virtualisation, I really need 
someone to go through this with me.
Please?

Cheers
Simon
