<div dir="ltr">Hi Hossein, I wouldn't use a VM from the cloud as a controller failover, it would complicate things unnecessarily. What I would do is: use one of the compute nodes a controller failover. You can install the APIs easily on the compute node and the rest of the software too.</div><div class="gmail_extra"><br><div class="gmail_quote">2014-10-26 10:38 GMT-03:00 Hossein Zabolzadeh <span dir="ltr"><<a href="mailto:zabolzadeh@gmail.com" target="_blank">zabolzadeh@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">With three node deployment in mind(one controller and 2 compute<br>
nodes), in order to acheive minimum HA with threse three physical<br>
nodes, is it possible to setup second controller as a virtual machine<br>
on one of my compute node?<br>
Does this approach improve HA in my deployment(atleast until my other<br>
physical nodes become available)?<br>
Thanks in advance.<br>
