libvirt shared folders with windows xp as guest while mounting I get

Hi everyone,

I'm trying to setup libvirt to allow me to use shared folders without success. I have a VM with Windows XP, installed libvirt and Virtual Machine Manager, have added as hardware a "Filesystem shared" folder with the bellow:
Type: mount
Driver: Default
Mode: Mapped
Source path: /backup/DEV/VMs/SWAP
Target path: shared

when I mount it like this:

sudo mount -t 9p -o trans=virtio shared /backup/DEV/VMs/SWAP/ -oversion=9p2000.L

I get:

mount: special device shared does not exist

I have the proper modules loaded:

$ lsmod | grep virt
virtio_scsi            20480  0
virtio_net             32768  0
virtio_blk             20480  0
virtio_balloon         16384  0
9pnet_virtio           20480  0
virtio_ring            20480  5 virtio_blk,virtio_net,virtio_balloon,9pnet_virtio,virtio_scsi
virtio                 16384  5 virtio_blk,virtio_net,virtio_balloon,9pnet_virtio,virtio_scsi
9pnet                  73728  2 9p,9pnet_virtio
scsi_mod              147456  3 libata,sd_mod,virtio_scsi

my WindowsXP.xml file:

...
    <filesystem type='mount' accessmode='mapped'>
      <source dir='/backup/DEV/VMs/SWAP'/>
      <target dir='shared'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </filesystem>
...

my libvirt/qemu log file:

any help would be appreciated. Thanks,
