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

Howdy,

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

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

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*

# 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

I even added the following in to my 
/var/lib/*xend*/devices/xxxxx/config.sxp:

************************************************
I''ve installed F9 (64-bit) with virtualization
package as it was.
First attempt to create SNV89 KVM failed to read
ISO and i just retried (back,forward) and succeeded
with SNV89 KVM as well as QEMU installs
Next attempt OpenSolaris 2008/05 KVM successful
with no retries.

I had the same issue with FC8 domU not seeing pcibacked devices.  Centos as
a dom0 and domU works though.
