Since the release of Acropolis 4.5 there have been some great community posts and videos on VM high availability resources that I wanted to gather in one place. I think the key difference between competing hypervisors is the fact that our management layer is built to be highly available. Having the ability to always know the underlying resources gives AHV an advantage on making sure your resources are used wisely with management overhead. The following resources talk about HA and how to configure it in your environment.
