[Qemu-devel] [PATCH] qemu-options: add documentation for using UDP unicast network backend. |
Date: |
Mon, 19 Oct 2015 12:49:15 +0300 |
For a long time QEMU has had support for UDP unicast network
backend, but manual was missing description and usage examples.
This patch adds some more documentation and an example.

+Connect a VLAN @var{n} to a remote VLAN in another QEMU virtual
+machine using a UDP tunnel. Use lport as local port and rport as
+remote port of the tunnel. The two QEMU can be running on
+different hosts. Use @option{fd=h} to specify an already opened
+UDP socket.
