This is the "fixed appliance", a pre-built binary appliance for
libguestfs. This was built using $program.
Unpack the appliance directory:
tar -Jxvf appliance-<VERSION>.tar.xz
Then copy all four files:
* kernel
* initrd
* root
* README.fixed
into a directory somewhere, eg. /usr/local/lib/guestfs/appliance/
Then build libguestfs (>= 1.16.7 or >= 1.18) from source, disabling
the normal appliance and daemon:
./configure --disable-appliance --disable-daemon
make
sudo make install
Set LIBGUESTFS_PATH to the path where you unpacked these files, eg:
export LIBGUESTFS_PATH=/usr/local/lib/guestfs/appliance/
and run the libguestfs programs and virt tools in the normal way.
LICENSE
-------
This appliance contains software under a variety of open source
licenses. The software is from Fedora (https://fedoraproject.org/),
and to rebuild it you need to download Fedora 17+ and
libguestfs >= 1.17.10, and build libguestfs from source in the usual
way.
