Hi guys,

I have a problem with the nova scheduler and the capabilities update period.

For Example:

If I have a flavor with the extra_specs key / value pair:

vcpus_used = '<= 2'

So, virtual machines should be submitted if the host not more than two vcpus
used.

However I'm able to start more than two machines, if I do it fast enough.
So I have the situation, that for example 5 vms are already running, and I'm
still able to submit new machines on that host.

If I wait (let's say a minute), the capability "vcpus_used" will be
upgraded, and at that point the filter works.

So my question.

Is there a possibility to update the host capabilities with every VM submit?

PS: I used folsom.

Cheers Viktor Mauch
