This means you have not installed the libvirt, libxl driver. Or that
you have, but trying to load it is failing.

There should be something in the libvirt logs.

However, since you said you've installed Xen from sources, you probably
need to build and install libvirt from sources too.

In fact, I don't know how exactly it is in Ubuntu, but in all the
distro I've tried, trying to install libvirt-daemon-driver-libxl (or
whatever the package is called), would fail, unless Xen hypervisor,
toolstack and libraries are also installed with the distro package
mamanger.

If that is not the case, install would either fail, or would bring in
those Xen packages, which would then either overrun or conflict with
your source installation.

As said above. In all the distro I tried, when I build Xen from source,
I've always also had to build libvirt from sources.
