Connecting emulated networks between QEMU instances Using the -netdev socket (or -nic socket or -net socket) option, it is possible to create emulated networks that span several QEMU instances. See the description of the -netdev socket option in Invocation to have a basic example.
qemu -h
Network options:
-netdev user,id=str[,ipv4[=on|off]][,net=addr[/mask]][,host=addr]
[,ipv6[=on|off]][,ipv6-net=addr[/int]][,ipv6-host=addr]
[,restrict=on|off][,hostname=host][,dhcpstart=addr]
[,dns=addr][,ipv6-dns=addr][,dnssearch=domain][,domainname=domain]
[,tftp=dir][,tftp-server-name=name][,bootfile=f][,hostfwd=rule][,guestfwd=rule][,smb=dir[,smbserver=addr]]
configure a user mode network backend with ID 'str',
its DHCP server and optional services
-netdev tap,id=str[,fd=h][,fds=x:y:...:z][,ifname=name][,script=file][,downscript=dfile]
[,br=bridge][,helper=helper][,sndbuf=nbytes][,vnet_hdr=on|off][,vhost=on|off]
[,vhostfd=h][,vhostfds=x:y:...:z][,vhostforce=on|off][,queues=n]
[,poll-us=n]
configure a host TAP network backend with ID 'str'
connected to a bridge (default=br0)
use network scripts 'file' (default=/etc/qemu-ifup)
to configure it and 'dfile' (default=/etc/qemu-ifdown)
to deconfigure it
use '[down]script=no' to disable script execution
use network helper 'helper' (default=/usr/lib/qemu/qemu-bridge-helper) to
configure it
use 'fd=h' to connect to an already opened TAP interface
use 'fds=x:y:...:z' to connect to already opened multiqueue capable TAP interfaces
use 'sndbuf=nbytes' to limit the size of the send buffer (the
default is disabled 'sndbuf=0' to enable flow control set 'sndbuf=1048576')
use vnet_hdr=off to avoid enabling the IFF_VNET_HDR tap flag
use vnet_hdr=on to make the lack of IFF_VNET_HDR support an error condition
use vhost=on to enable experimental in kernel accelerator
(only has effect for virtio guests which use MSIX)
use vhostforce=on to force vhost on for non-MSIX virtio guests
use 'vhostfd=h' to connect to an already opened vhost net device
use 'vhostfds=x:y:...:z to connect to multiple already opened vhost net devices
use 'queues=n' to specify the number of queues to be created for multiqueue TAP
use 'poll-us=n' to speciy the maximum number of microseconds that could be
spent on busy polling for vhost net
-netdev bridge,id=str[,br=bridge][,helper=helper]
configure a host TAP network backend with ID 'str' that is
connected to a bridge (default=br0)
using the program 'helper (default=/usr/lib/qemu/qemu-bridge-helper)
-netdev l2tpv3,id=str,src=srcaddr,dst=dstaddr[,srcport=srcport][,dstport=dstport]
[,rxsession=rxsession],txsession=txsession[,ipv6=on/off][,udp=on/off]
[,cookie64=on/off][,counter][,pincounter][,txcookie=txcookie]
[,rxcookie=rxcookie][,offset=offset]
configure a network backend with ID 'str' connected to
an Ethernet over L2TPv3 pseudowire.
Linux kernel 3.3+ as well as most routers can talk
L2TPv3. This transport allows connecting a VM to a VM,
VM to a router and even VM to Host. It is a nearly-universal
standard (RFC3391). Note - this implementation uses static
pre-configured tunnels (same as the Linux kernel).
use 'src=' to specify source address
use 'dst=' to specify destination address
use 'udp=on' to specify udp encapsulation
use 'srcport=' to specify source udp port
use 'dstport=' to specify destination udp port
use 'ipv6=on' to force v6
L2TPv3 uses cookies to prevent misconfiguration as
well as a weak security measure
use 'rxcookie=0x012345678' to specify a rxcookie
use 'txcookie=0x012345678' to specify a txcookie
use 'cookie64=on' to set cookie size to 64 bit, otherwise 32
use 'counter=off' to force a 'cut-down' L2TPv3 with no counter
use 'pincounter=on' to work around broken counter handling in peer
use 'offset=X' to add an extra offset between header and data
-netdev socket,id=str[,fd=h][,listen=[host]:port][,connect=host:port]
configure a network backend to connect to another network
using a socket connection
-netdev socket,id=str[,fd=h][,mcast=maddr:port[,localaddr=addr]]
configure a network backend to connect to a multicast maddr and port
use 'localaddr=addr' to specify the host address to send packets from
-netdev socket,id=str[,fd=h][,udp=host:port][,localaddr=host:port]
configure a network backend to connect to another network
using an UDP tunnel
-netdev vhost-user,id=str,chardev=dev[,vhostforce=on|off]
configure a vhost-user network, backed by a chardev 'dev'
-netdev hubport,id=str,hubid=n[,netdev=nd]
configure a hub port on the hub with ID 'n'
-nic [tap|bridge|user|l2tpv3|vhost-user|socket][,option][,...][mac=macaddr]
initialize an on-board / default host NIC (using MAC address
macaddr) and connect it to the given host network backend
-nic none use it alone to have zero network devices (the default is to
provided a 'user' network connection)
-net nic[,macaddr=mac][,model=type][,name=str][,addr=str][,vectors=v]
configure or create an on-board (or machine default) NIC and
connect it to hub 0 (please use -nic unless you need a hub)
-net [user|tap|bridge|socket][,option][,option][,...]
old way to initialize a host network interface
(use the -netdev option if possible instead)

What precisely has changed in v197?
With systemd 197 we have added native support for a number of different naming policies into systemd/udevd proper and made a scheme similar to biosdevname's (but generally more powerful, and closer to kernel-internal device identification schemes) the default. The following different naming schemes for network interfaces are now supported by udev natively:
Names incorporating Firmware/BIOS provided index numbers for on-board devices (example: eno1)
Names incorporating Firmware/BIOS provided PCI Express hotplug slot index numbers (example: ens1)
Names incorporating physical/geographical location of the connector of the hardware (example: enp2s0)
Names incorporating the interfaces's MAC address (example: enx78e7d1ea46da)
Classic, unpredictable kernel-native ethX naming (example: eth0)

# To plug a device into pcie.0 as a Root Complex Integrated Endpoint use:
