As I said in the previous message, I'd rebuild the Debian package
instead of building from source. That way, you should be able to
seamlessly replace the version of libvirt that you had installed from
Ubuntu 20.04's repositories with a newer one.

The steps involved should be roughly

  $ sudo apt-get update
  $ sudo apt-get install -y build-essential
  $ sudo apt-get build-dep -y libvirt

to install the necessary build dependencies, and then

  $ dget https://deb.debian.org/debian/pool/main/libv/libvirt/libvirt_8.5.0-1.dsc
  $ cd libvirt-8.5.0/
  $ dpkg-buildpackage --no-sign

to actually build the package. Assuming there are no errors, you
should end up with a bunch of .deb files that you can install on the
system using apt-get.
