Hi, Non-root can't use /var/run/libvirt/libvirt-sock even in the case "unix_sock_group" and "unix_sock_rw_perms" are set properly. The reason: # ls -l /var/run /var/run/libvirt | grep libvirt | grep -v pid drwx------ 2 root root 4096 Apr 14 19:14 libvirt srwxrwx--- 1 root libvirt 0 Apr 14 19:14 libvirt-sock srwxrwxrwx 1 root libvirt 0 Apr 14 19:14 libvirt-sock-ro i.e., bad permissions on /var/run/libvirt One possible solution (implied in the attached patch) is the following: Every time libvirtd starts * it implicitly sets the group id of /var/run/libvirt: chown(/var/run/libvirt, -1, unix_sock_gid). * if "unix_sock_group" defined in /etc/libvirt/libvirtd.conf, libvirtd does chmod g+x /var/run/libvirt otherwise, chmod g-x /var/run/libvirt A.
