Hi Daniel,<br>
<br>
I dont know if there is any connection between ¨Kernel panic error ¨ and ¨<b>Server disconnected (code: 1006)</b>¨ errors. When I´m trying to deploy a Debian VM using other template, I get a message ¨<b>Server disconnected (code: 1006)</b>¨<b>.
</b>Therefore, I cannot eventually<b> </b>connect through sunstone using VNC to any of my VM´es.<br>
<br>
Following the previous threads I also verified these possibilities to find the problem but sunstone is still showing the Server disconnected msg.<br>
<pre style="margin: 0em;"><br>Check sunstone.error too. <b>--> EMPTY</b>
</pre>
<tt>Check that no websockify from a previous session is running (ps aux | grep </tt>
<tt>websockify).<b>--> NO</b><br>
</tt>
<pre style="margin: 0em;">Check that you have run ./install_novnc.sh after your upgrade. <b>--> DONE</b>
</pre>
<tt>Check that you can still connect to the machine VNC with a different vnc </tt>
<tt>client directly. <b>--> When I try with virt-manager I get the same error than at the beginning of this Thread ¨Kernel panic ...¨</b><br>
<br>
</tt>
<pre style="margin: 0em;">Is the "starting vnc proxy" line showing up in sunstone.log? <b>--> YES</b>
</pre>
<tt>From which version were you upgrading? You can attach sunstone.log so I </tt>
<tt>can check if I see something that you missed. <b>--> I am using the last version of Opennebula 3.6.0-1<br>
<br>
The content of sunstone.log is:</b><br>

Did you get these errors before ? I think I need to configure something at the BOOT parameters of my virtual image template but I don´t know what.<br>
<br>
I also attached a png file to show you the error.<br>
