Following on this thread, in this 2 switches 2 hosts setup, are there
two separate connections from both vigil1 and vigil2 to the host machine
(by s1_SLIRP and s2_SLIRP)? Also, does this mean that we need to use
secchan to connect to the nox_core on the host machine, from both vigil1
and vigil2?
Then, what if I only setup one secure channel between vigil1 and the
host nox using secchan? Will vigil1 and vigil2 form a spanning tree, and
vigil1 will forward control messages for vigil2? I am a little confused
here.
Thank you so much,

The number of VMs and their connectivity are specified in the vms.conf
file. As an example, here is a file with four VMs total, two acting
as switches (vigil1 & vigil2) and two acting as regular machines (end1
and end2), one connected to each switch. To add more VMs, just add
new names to the VMS line. The "SWITCHES" provide the connectivity
for the VMs connected to them using the *_NETS lines as a regular
(non-openflow) switch would.

Hi All,
I did the virtual test environment setup using NOX with 1 controller,
1 switch and 2 virtual QEMU machines as suggested in the wiki.
I want to build upwards from this configuration and have more nodes
and switches under the purview of the NOX controller.
Could you please suggest what would be the best way to emulate more
complicated (close to real life networks) using the NOX controller.
Thanks a lot!
Regards,
Surabhi
