How to launch an OpenStack instance in a specific host aggregate

#Make sure AggregateImagePropertiesIsolation is enabled in nova.conf
scheduler_default_filters=AggregateImagePropertiesIsolation

# Restart all nova services on all controllers

# Create host aggregates
# For example one aggregate for ESX and one for KVM
nova aggregate-create ESX-AZ ESX-AZ
nova aggregate-create KVM-AZ KVM-AZ

# List aggregates so you can find out the number
nova aggregate-list

# Add a host to each aggregate
nova aggregate-add-host <aggregate number for ESX from above> ESX-Host1
nova aggregate-add-host <aggregate number for KVM from above> KVM-Host1

# By default when you create an AZ it adds metadata "availability_zone=<name of AZ>"

# We can use this to update the image metadata so it spins up in the correct AZ. 

# Add metadata to spin up vmdk in ESX AZ
glance image-update <VMDK img-uuid> --property availability_zone="ESX-AZ"

# Add metadata to spin up qcow2 in KVM AZ
glance image-update <QCOW2 img-uuid> --property availability_zone="KVM-AZ"

# Now you can test the new image and confirm it spins up on the correct host in the specified aggregate

nova boot --image ubuntu14 --flavor m1.small --nic net-id=<network ID> Test_ESX1
nova list | grep Test_ESX1
nova show <ID from above> |grep zone 

# You should see the image is on the correct host aggregate.  If not enable debug in /etc/nova/nova.conf 
# Restart nova services on all controllers. Then check out /var/log/nova/nova-scheduler.log
