With three node deployment in mind(one controller and 2 compute nodes), in order to acheive minimum HA with threse three physical nodes, is it possible to setup second controller as a virtual machine on one of my compute node? Does this approach improve HA in my deployment(atleast until my other physical nodes become available)? Thanks in advance.
