It is managed by the scheduler. Admins can force a specific host by passing in availabilty zone like so:
nova boot --availability_zone nova:HOST
where HOST is the name of the host that you want it to boot on. Note that this will skip the scheduler altogether so it is possible to overallocate a host this way.
or an example post in json:
{
"server" : {
"name" : "new-server-test",
"imageRef" : "70a599e0-31e7-49b7-b260-868f441e862b",
"flavorRef" : "1",
"availability_zone": "nova:HOST",
}
}
