+Please note that additional configuration is required if you want to run
+ovs-vswitchd with DPDK backend inside a QEMU virtual machine. Ovs-vswitchd
+creates separate DPDK TX queues for each CPU core available. This operation
+fails inside QEMU virtual machine because, by default, VirtIO NIC provided

+You may do it manually (by changing QEMU command line) or, if you use Libvirt,
