I don't know what the correct way to build a .deb package is, The easiest way is to use a package from a newer Ubuntu version. I'd suggest using the oldest good enough version available to avoid problems with dependencies. You may still be forced to use a newer libc or so. In such a case, you can either configure your system (in /etc/apt/) to use some packages from a newer Ubuntu version, or to rebuild the newer libvirt package using instructions from https://wiki.debian.org/BuildingTutorial#The_packaging_workflow > but on rpm based distros I usually build a .tar.xz (meson dist) from > which I build a .rpm (rpmbuild -ta) and then install it. > > Michal
