Libvirt group neccessary?

I was working on automatically adding groups to user “user” for better usability as we talked about a while ago.

Debian maintainer scripts are located in /var/lib/dpkg/info/… I saw code for adding the group “kvm” in /var/lib/dpkg/info/qemu-system-common.postinst. But no code to add the group “libvirt”. Only code to delete group “libvirt” in /var/lib/dpkg/info/libvirt-bin.postrm. It also deletes group “libvirt-qemu”. So I am wondering wheter the last two groups “libvirt” and “libvirt-qemu” have been deprecated? If that was the case, there would be no need re-create them in usability-misc.postinst.

According to Debian’s documentation that has been updated pretty recently this year, 2 groups are needed for KVM, they are libvirt and kvm.

So yes, it seems to need the libvirt group too. This makes sense becuase libvirt is a separate component than kvm, and its a virtualization abstraction layer that supports many different programs.

Anyone can edit Debian wiki. It’s not a primary, authoritative source. That edit was non-malicious and probably well intentioned. Yet, I don’t know if someone added that information who knows this is required or just added what was necessary in earlier versions.

Anyhow. In this specific case the libvirt group is documented in /usr/share/doc/libvirt-bin/README.Debian. Also documents the other groups, we don’t have to add. Also found how its created in the “apt-get source libvirt-bin” in debian/libvirt-bin.postinst. For some reason that file is not on my local hdd but the libvirt debian source.

This is now implemented:
