[libvirt-users] How to run libvirtd as non root user
Team, I note that libvertd runs as root user that is against the least privilege security model. root 307278 1 0 Jun20 ? 04:16:46 /usr/sbin/libvirtd -listen Appreciate pointers to alternate options that user could configure as a potential mitigation plan? Thanks, -Anshul

Sadly, that IS the least privilege required for successfully running qemu:///system or lxc:/// guests.

Use qemu:///session connections - that runs a separate libvirtd process as the current user, just fine. Without privileges, your guests will have a harder time using networking, but that's what you'd expect. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

To enhance this experience, make sure that /dev/kvm is writable by the current user, and configure qemu-bridge-helper (and make sure it's setuid).
