<div>With tags we can boot instances to a specified host aggregate.</div>
<div>But in case when we need boot instances to a specified host, available zone is a good approach.</div>
<div>Otherwise, we need to provide tagged flavors for each host. In real use I think it’s quite impossible.</div>

<br>
Users don't know anything about host aggregates. They are a cloud-admin-only way of grouping like compute resources together and the end user doesn't have any way of specifying a particular host aggregate when launching an instance.<br>

Hi, All<br>
<br>
I used to use below command to boot an instance with a specified IP<br>
address to a<br>
Specified compute node.<br>
<br>
nova boot<br>
--image <image-id> \<br>
--flavor <flavor-id> \<br>
--nic net-id=<network-id>,v4-fixed-i<wbr>p=<ip addr> \<br>
--availability-zone <AZ>:<host><br>

<br>
May it helps.<br>
