Hi Tony,

Your reply gave me a hint that nova-consoleauth service must be running. I
did not start that service before so no token authentication was done. Now
after starting the service,
$nova get-serial-console vm-check-6

| Type   | Url                                                             |

Following
http://docs.openstack.org/developer/nova/testing/serial-console.html

$ python client.py ws://
127.0.0.1:6083/?token=c2fb4073-79a0-44b9-a977-cc7a1fa074f6

..............hangs

Log at consoleauth shows that the token authentication is done.

In nova.conf I have only made enabled=true under [serial-proxy] section.
Other values are not specified so that letting the nova take default
values. I have read that with default values single node set up will not
have any issues.

I thought the issue might be because of websocket, so I was not able to
install websocket module of python in my system.

system-specifications :

    uname -m = aarch64
    uname -r = 4.2.0-03373-gdded870-dirty
    uname -s = Linux
    uname -v = #4 SMP Tue Dec 8 14:47:17 IST 2015

Error while installing :
    libev/ev.c:45:22: fatal error: config.h: No such file or directory
     #  include "config.h"
                          ^
    compilation terminated.
    error: command 'aarch64-linux-gnu-gcc' failed with exit status 1


Please help me how to proceed further.

Thanks,
Prathyusha
