OK, I understand it now. Then, does Opennebula support any kind of
overcommitting or something?

Well, capacity could mean many things. I am not sure. See the
attached screen shot.
The hosts have 2 kinds of capacity: real and allocated.
Real is the cpu/mem as reported by the monitoring probes.
Allocated is the amount of cpu/mem requested by the VMs running on this
host. This is the one used for scheduling.
In your case, the new VM requests 400 cpu. But the host has already
allocated 500 out of 800, this is why the scheduler decides that it
doesn't fit.

I understand, but there is nothing there. Absolutely empty.

That's what I meant when I said "there are no logs".

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