20.16.9.5. Generic Ethernet connection
Provides a means for the administrator to execute an arbitrary script to connect the guest virtual machine's network to the LAN. The guest virtual machine will have a
tun
device created with a name of vnetN
, which can also be overridden with the target
element. After creating the tun
device a shell script will be run which is expected to do whatever host physical machine network integration is required. By default this script is called /etc/qemu-ifup
but can be overridden (refer to Section 20.16.9.11, “Overriding the target element”).
The generic Ethernet connection parameters are defined in the following part of the domain XML:
... <devices> <interface type='ethernet'/> ... <interface type='ethernet'> <target dev='vnet7'/> <script path='/etc/qemu-ifup-mynet'/> </interface> </devices> ...
