That's strange. You should have the following message:<br>

I understand, but there is nothing there. Absolutely empty.<span class=""><br>

Admins and advanced users can see the scheduler error messages<br>
in sunstone, under the placement VM tab.<br>
<br>
That's what I meant when I said "there are no logs".<br>
<br>
<br>
That's strange. You should have the following message:<br>

<br>
On the other hand, I didn't know about /var/log/one/sched.log. Here<br>
is what I found there:<br>

<br>
Does host 0 have enough capacity? Those numbers refer to the allocated<br>
capacity, as can be seen in sunstone or the onehost show output.<br>
