vm console showing blank screen

[rohit]

Hi,
I installed openstack using devstack on new ubuntu machine, it installed properly, and VM also instantiated successfully, but when I try to access console of VM instance, it is simply showing blank screen..
I checked novnc server , it is working and receiving requests.
I am running followsing services :-

disable_service n-net
enable_service neutron q-svc q-agt q-dhcp q-l3 q-meta
disable_service n-spice
enable_service n-novnc
disable_service n-xvnc
enable_service n-sproxy
disable_service tempest

this problem is coming on liberty as well as on mitaka.

could this problem relates to system hardware also?

I failed to reproduce the bug.

I am using RDO with an all in one installation.

[Qijing Li (qijing-lee)]

This bug did not happen on my devstack on ubuntu.

Here is my local.conf

 # Do not use Nova-Network
 disable_service n-net
 # Enable Neutron
 ENABLED_SERVICES+=,q-svc,q-dhcp,q-meta,q-agt,q-l3

Hi,
my os is ubuntu 16 .10 (xenial), is it related with some specific OS version?
I will try with other OS.

[Maciej Szankin (mszankin)]

Tested current master branch on 16.04 with local.conf just as in bug description and everything works correctly.

Are you sure that console is available on the same IP as the VM? And if not, that this IP is ping-able?

Marking as invalid until any further proof appears.
