Select a specific zone to boot instances on

It is possible to specify which availability zone to run the instance on using the nova client. In order to use such feature, make sure you are using an admin account.

You can determine the current active zone by looking at the nova.conf file for the compute node and seeing the node_availability_zone=yyyyy where yyyyy is the name of the zone the host is affiliated with.

We see here our "server2" lives in the "nova" availability zone. You can now select the host on which the instance would be spawned, using the "--availability-zone" parameter as an admin.

	Note
	The --force_hosts scheduler hint has been replaced with --availability_zone in the Folsom release.

$ nova boot --image <uuid> --flavor m1.tiny --key_name test --availability-zone nova:server2
