Hello,
I have a question about nova-scheduler. I believe that, in order to have
viable values supplied to the scheduler filters, it gathers the most recent
state from each of the compute host. However, i've read through the
documentation and haven't found any explicit statement which confirm my
Yes.
By default, once in two minutes host's capabilities are refreshed in
nova-scheduler. These capabilities are then used along with data from
DB to form current host capabilities. After that, resources used by
each instance on the host are subtracted from it. The result
containing the actual
3 matches
