Hi,

I have enabled host aggregates to aid scheduling instances on hosts
with cpus of the same type (in order to test live migration). But after
I set it up, scheduling flavor with the extra_specs key-value pair always
fail.

The logs did not help much. How can I debug this problem?

I'm running the Havana version in a test environment. Nova controller and
nova-compute are on different nodes.

Thanks,
Yuanle

This is the command use to boot the instance:

bin/nova boot --flavor lm.c1 --key_name sylecn_at_vboxw1 --image
cirros-0.3.1 --nic net-id=$VM_NET_ID c8

booting other flavor works fine on the same nova-compute node (
ceph3.geocast.net).

Here is the host aggregates setup:

/etc/nova/nova.conf
===================
scheduler_default_filters=RetryFilter,AggregateInstanceExtraSpecsFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter

All nova services are restarted after updating nova.conf.
