Actual VM is started by libvirtd, which is likely running under libvirt/qemu user and group. It will not have access to sockets created by ovs-vswitchd unless ovs-vswitchd is running under the same user or group. It would likely be easier if you install OVS as a deb/rpm package depending on your operating system. It will be managed as a systemd service with a correct user/group configuration. You may install packages from your distribution or build them from sources using guides: https://docs.openvswitch.org/en/stable/intro/install/debian/ https://docs.openvswitch.org/en/stable/intro/install/fedora/ >> >> I have create ovs bridge with sudo , also > > > Here is a link to what I normally do under Fedora/RHEL.
