QEMU previously used the -net nic option instead of -device DEVNAME and -net TYPE instead of -netdev TYPE. Misc The legacy -net option. Pass QEMU a physical card rather than emulation/simulation.

QEMU can emulate several different models of network card. If no -net option is specified, a single NIC is created. Optionally, for PCI cards, you can specify the number v of MSI-X vectors that theCard should have this option currently only affects virtio cards set v = 0 to disable MSI-X. Optionally, the MAC adвЂђDress can be changed to mac, the device address set to addr (PCI cards only), and a name can be assigned for use in monitor commands. Note that the default NIC model may change in future QEMU releases, so it is highly recommended to always specify a model.

Only use this if running a QEMU guest as an unprivileged user. The guest will be NATed to the LAN by whichever connection is active.Type=direct,source=IFACEDirect connect to host interface IFACE using macvtap.User Connect to the LAN using SLIRP. Use a virtual network if the host has dynamic networking (eg NetworkManager), or using wireless.

This is used for 802.Qbg, 802.Qbh, midonet, and openvswitch config.Use -network=? to see a list of all available sub options. Available filters can be listed by running 'virsh nwfilter-list', e.g.: 'clean-traffic',Configure the device virtual port profile. Value can be any nwfilter defined by the virsh 'nwfilter' subcommands.
