No need for libvirtd on the Hyper-V server. The libvirt on your Linux
machine will directly talk to the Hyper-V management API on the
Hyper-V server.

That error message gives you the wrong impression. Your problem is
probably that your libvirt version on the Linux machine is too old and
doesn't have support for Hyper-V yet.

Basic Hyper-V support was added in libvirt version 0.9.5.
