Hi, The current solution for running OVS with non-root user in Fedora makes it not possible to support UIO drivers [1]. Setting the user to root:root via /etc/sysconfig/openvswitch should be a solution, but it is also currently broken, since the systemd ovs-vswitchd.service is forcing the group :hugetlbfs to /dev/hugepages [2], which breaks root access to it. Would it be possible to change the permissions only if the user in not root? Currently I can only make UIO work on fedora removing this hardcoded permissions on the systemd files. I believe that either root:root should not conflict with the systemd script or be explicitly unsupported.
[1] For Linux kernel 4.0 and newer, the ability to obtain physical page frame numbers for unprivileged users from /proc/self/pagemap was removed.
