[libvirt] improve security by adjusting the privileges of libvirtd processes

Hi Team The daemon libvirtd runs as root user, which against the least privilege security model. root 567642 1.2 0.0 2856020 47576 ? Ssl 15:49 0:02 /usr/sbin/libvirtd --listen In addition, the "--listen" parameter exposes TCP or TLS ports on the network, it increasing the attack surface. tcp 0 0 0.0.0.0:16509 0.0.0.0:* LISTEN 647824/libvirtd tcp 0 0 0.0.0.0:16514 0.0.0.0:* LISTEN 647824/libvirtd I have the following puzzles: 1. Whether root is the least privilege required for libvirtd to manage virtualization platforms, it's possible to run libvirtd as a non-root user? 2. Is there any plan to resolve this security weaknesses? (like move the function of "--listen" to an independent non-root process, or other better schemes) Regards, BiaoXiang
