Guest with provisioned disk
----------------
To add guest rootfs partition to host wic image,
set `AUTONOMY_HOST_EXTRA_PARTITION` with proper wks partition entry, e.g:
```
AUTONOMY_HOST_EXTRA_PARTITION = "part --label provisioned-guest --source rawcopy --fstype=ext4 --ondisk sda --align 1024 \
--sourceparams=file=${TOPDIR}/${MC_GUEST}/deploy/images/${MC_GUEST_MACHINE}/${MC_GUEST_FILENAME_PREFIX}-${MC_GUEST_MACHINE}.ext4"
```
inside host.conf file.
The rest of the configuration has to be appended to guest.conf file:
```
XENGUEST_IMAGE_DISK_SIZE = "0"
XENGUEST_IMAGE_SRC_URI_XEN_CONFIG = "file://\${TOPDIR}/path/to/rootdisk.cfg"
XENGUEST_IMAGE_DISK_DEVICE = "_GUEST_DISK_DEVICE_"
XENGUEST_IMAGE_ROOT = "/dev/xvda"
IMAGE_ROOTFS_SIZE = "102400"
IMAGE_FSTYPES = "ext4"
```
content of rootdisk.cfg"
```
disk = ["phy:_GUEST_DISK_DEVICE_,xvda,w"]
```
`_GUEST_DISK_DEVICE_` should be substituted with `/dev/sdaX`,
according to wks file.
