<br>
so can you please check if neutron works well?<br>
<br>
BTW, I don't think no host found is due to RAM issue.<br>
<br>
Just my 2 cents.<br>
<br>
Thanks, Eli.<br>

Your host has 3.7G of RAM, but not all of them available for
your instances. If your host is in virtualized environment, try
to increase the RAM size and choose the minimum flavor possible
for your image. <br>
