Commit 7068b56c introduced several hyperv features. Not all hyperv features are supported by old enough kernels and we shouldn't allow to start a guest if kernel doesn't support any of the hyperv feature. There is one exception, for backward compatibility we cannot error out if one of the RELAXED, VAPIC or SPINLOCKS isn't supported, for the same reason we ignore invtsc, to not break restoring saved domains with older libvirt.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
