Hi Lucas, It is working perfectly, until I'm restarting my network (using ifreload, Is it still expected to have this behavior ? Yes, I think it's expected, and the scenario is similar with https://bugzilla.redhat.com/show_bug.cgi?id=1730084#c36 What would be a better way to configure the network ? Refer to the https://libvirt.org/formatdomain.html#bridge-to-lan, it is recommended to use Linux bridge instead of ovs bridge. Thanks.
