Re: [vizstack-users] Configuring VizStack - TurboVNC server failed to start - Problem

[Cristi M. <Cri...@ne...>]

Hello again,

First of all I would like to say - Thank You Shree ! - for your notes
about the packages that need to be installed manually for Ubuntu Server !

Now I have the following use case:

On the master node (node0) I run the following

/opt/vizstack/sbin/vs-configure-system -s slurm cgis[1-2]

Everything is working fine here.
Result:

--------------------------------------------------------------------------
The summary of this configuration is :

SSM is running at host 'cgis0', port '50000'


  - 2 nodes will be managed by the SSM
    - 2 GPU(s) are available
    - 1 GPU(s) are configured for shared usage
    - scheduler used will be 'slurm'
    - see file '/etc/vizstack/node_config.xml' for node configuration &
scheduler details



To activate this configuration, you need to start the SSM
  # /opt/vizstack/sbin/vs-ssm start

One or more files were backed up during this configuration.
All the original files have been backed up with a name suffix
'.Wed_Jan_19_12:53:39_2011'

---------------------------------------------------------------------------

After this I run /opt/vizstack/sbin/vs-ssm start and the SSM Status is OK.

Result:
VizStack SSM daemon is running with pid=23656

Then I run: viz-tvnc

Result:
Starting Desktop with resolution 1280x1024
TurboVNC server failed to start.


So, I guess the problem regarding this TurboVNC server is comming from:

except vsapi.VizError, e:
	showError(isAutomation,"TurboVNC server failed to start"


I have installed the following packages on all the nodes:
- turbovnc_1.0_amd64.deb
- VirtualGL_2.2_amd64.deb
- turbojpeg_1.11.1_amd64.deb


Do you know why the TurboVNC server failed to start ?
I tried to run these commands on another node with GPU:
/opt/vizstack/sbin/vs-configure-standalone
/opt/vizstack/sbin/vs-ssm start
viz-tvnc

Result:
Starting Desktop with resolution 1280x1024
TurboVNC server failed to start.

Thank you in advance !

Regards,
Cristi
