Re: [libvirt-users] "scripts are not supported on interfaces of type vhostuser" error

[...] > <interface type="vhostuser"> > <script path="/opt/oa/etc/qemu-ifup"/> ^^^^^^^^^^^^^^^^ Why do you have this line? Spo> $ virsh create vm.xml > error: Failed to create domain from vm.xml > error: unsupported configuration: scripts are not supported on > interfaces of type vhostuser This error message tells you exactly what is wrong. The <script> element is only supported for interfaces of type='ethernet' - these are interfaces for which a tap device is created, but it's not connected to anything; the purpose of the script is to connect the tap to device to [something user-defined]. Other types of interface (e.g. vhost-user) should have enough intelligence built into the code to perform all necessary setup. Do you actually have something in this qemu-ifup file? > > > The logs from libvirtd.log say: > 2018-02-22 09:18:24.982+0000: 2033: warning : > qemuProcessStartWarnShmem:4539 : Detected vhost-user interface without > any shared memory, the interface might not be operational > 2018-02-22 09:18:24.982+0000: 2033: error : qemuBuildHostNetStr:3894 : > unsupported configuration: scripts are not supported on interfaces of > type vhostuser > > The logs from qemu simply say: > 2018-02-22 09:26:15.857+0000: shutting down, reason=failed > > And finally, ovs-vswitchd.log: > 2018-02-22T09:18:24.715Z|00328|dpdk|INFO|VHOST_CONFIG: vhost-user > client: socket created, fd: 51 > 2018-02-22T09:18:24.716Z|00329|netdev_dpdk|INFO|vHost User device '0.vm' > created in 'client' mode, using client socket '/opt/oa/vhost/0.vm.sock' > 2018-02-22T09:18:24.718Z|00330|dpdk|WARN|VHOST_CONFIG: failed to connect > to /opt/oa/vhost/0.vm.sock: No such file or directory > 2018-02-22T09:18:24.718Z|00331|dpdk|INFO|VHOST_CONFIG: > /opt/oa/vhost/0.vm.sock: reconnecting... > 2018-02-22T09:18:24.718Z|00332|bridge|INFO|bridge switch1: added > interface 0.vm on port 5 > > > Am I missing something on the openvswitch or on the libvirt side? > > It looks like openvswitch can't find /opt/oa/vhost/0.vm.sock, but isn't > either openvswitch or libvirt in charge of creating it? > Then, I'm not too sure about the error messages in libvirtd.log... > > My software versions are: libvirt 3.10.0, qemu 2.10.2, openvswitch 2.8.1 > and DPDK 17.11. > > Thanks a lot! > > Riccardo > > > _______________________________________________ > libvirt-users mailing list > libvirt-users(a)redhat.com > https://www.redhat.com/mailman/listinfo/libvirt-users >
