20.16.9.4. User-space SLIRP stack
Setting the user-space SLIRP stack parameters provides a virtual LAN with NAT to the outside world. The virtual network has DHCP and DNS services and will give the guest virtual machine an IP addresses starting from 10.0.2.15. The default router will be 10.0.2.2 and the DNS server will be 10.0.2.3. This networking is the only option for unprivileged users who need their guest virtual machines to have outgoing access.
The user-space SLIP stack parameters are defined in the following part of the domain XML::
... <devices> <interface type='user'/> ... <interface type='user'> <mac address="00:11:22:33:44:55"/> </interface> </devices> ...
