It's already built into the kernel:
*$* zcat /proc/config.gz | grep 9P
CONFIG_NET_*9P*=y
CONFIG_NET_*9P*_VIRTIO=y
# CONFIG_NET_*9P*_DEBUG is not set
CONFIG_*9P*_FS=y
# CONFIG_*9P*_FS_POSIX_ACL is not set
# CONFIG_*9P*_FS_SECURITY is not set
But it didn't work for me either, using qemu directly (no libvirt). I
didn't really investigate very far. For my application it ended up making
more sense to serve the user_data over HTTP using "cloud-config-url= " on
the linux command line in grub.
Thanks Geoff~
