<pre>Hi Javed,<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>the error "no valid host found" is thrown by the `nova-scheduler` <o:p></o:p></pre>
<pre>service (see [1] for details). <o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Depending on your testing environment you have to check different things:<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>1) An "All-In-One" DevStack[2] setup:<o:p></o:p></pre>
<pre> * check your `local.conf` file in your devstack folder. There should <o:p></o:p></pre>
<pre> be the following lines: <o:p></o:p></pre>
<pre> DEST=/opt/stack<o:p></o:p></pre>
<pre> LOGFILE=$DEST/logs/stack.sh.log<o:p></o:p></pre>
<pre> VERBOSE=True <o:p></o:p></pre>
<pre> SCREEN_LOGDIR=$DEST/logs/screen<o:p></o:p></pre>
<pre> * The log of the scheduler is then available at:<o:p></o:p></pre>
<pre> /opt/stack/logs/screen/screen-n-sch-log<o:p></o:p></pre>
<pre> * The scheduler log should contain more information about the cause<o:p></o:p></pre>
<pre>Afaik the changes will be applied when the services are restarted. You <o:p></o:p></pre>
<pre>can either execute the DevStack scripts `unstack.sh` and `stack.sh` or<o:p></o:p></pre>
<pre>use the screen tool (see [4]).<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>2) A dedicated controller node:<o:p></o:p></pre>
<pre>The default folder for nova logs is `/var/log/nova`. The scheduler log <o:p></o:p></pre>
<pre>should be there. Maybe you have to turn on debugging in the file <o:p></o:p></pre>
<pre>`/etc/nova/nova.conf` in the line `debug=true` and `verbose=true`.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>More infos about working with logs can be found at [3].<o:p></o:p></pre>
