Do you see anything in the placement.log? Are there enough resources on that node? If you have it installed you could check the current allocations with the osc-placement command: openstack resource provider list and then openstack resource provider show --allocations <UUID> Zitat von DHilsbos@performair.com:

Thank you for reading my previous email, despite its poor Subject.
I have attached a subset of the Nova Scheduler log, with debugging enabled. I have added line numbers to the beginning, in order to facilitate referencing.
At line 18 it appears to select the requested server for the migration, but then at line 38, it rejects it.
Am I missing something here? Is it unable to assign the resources through placement?

I'm having a problem, though I'm not certain of the full scope.
The most obvious issue is that I can't live migrate instances. The server I want to send the instance to gets filtered out, though I don't see any logs that tell me why it's being filtered out.
It might be related that all of my new instances seems to land on a single host.
An pointers on where to look for logs for Host Filters?
You'll want to set [DEFAULT]debug = True in the nova.conf for your nova-scheduler service and restart or HUP the service. And then the logging per scheduler filter (each one will show the starting and ending number of hosts) will be included at DEBUG log level in the nova-scheduler log.
