If you don't want to change OVS sources, then just install openvswitch package with 'apt install openvswitch-switch'. If you plan to modify the code, then follow the guide on how to build a package from sources: https://docs.openvswitch.org/en/stable/intro/install/debian/ > > > Regards > > Laurent > > > > Internal > -----Message d'origine----- > De : Ilya Maximets <i.maxim...@ovn.org> > Envoyé : vendredi 8 septembre 2023 14:15 > À : Eelco Chaudron <echau...@redhat.com>; Laurent Coloby > <laurent.col...@se.com> > Cc : i.maxim...@ovn.org; b...@openvswitch.org > Objet : Re: [ovs-discuss] open vswitch and libvirt > > [External email: Use caution with links and attachments] > > ________________________________ > > > > On 9/8/23 14:03, Eelco Chaudron via discuss wrote: >> >> >> On 8 Sep 2023, at 13:55, Laurent Coloby via discuss wrote: >> >>> Hello Michal and Ilya >>> >>> Thank you for your answser >>> >>> You are right >>> With trace I can see is it due to permission. >>> >>> All the commands are send with : sudo >>> >>> What do you mean by " because you're starting OVS manually from a root >>> user, IIUC" >>> >>> Sorry I'm a beginner in Linux >>> >>> For starting, I enter >>> >>> sudo ovs-ctl start >>> >>> To launch VM, : >>> sudo virsh start VM > > virsh is just a frontend for libvirtd.
