Today a vendor bluntly stated that VMWare provides the same failover and redundancy for SQL that would render "AlwaysOn" high availability unnecessary.
Essentially that VMWare would detect a problem and failover and have .9999 uptime
Can someone with active VMWare experience confirm this in real life or was this just a salesman polishing the car.

AlwaysOn provides failover cluster instances which can be fully mitigated by VMware vmotion. AlwaysOn also provides availability groups which allows a number of readable secondary databases, this VMware does not provide

In VMware you can use SRM or Vsphere replication but your server will act as if it's in failover state.
Once the failover occurs sql server boots up and starts from the replicated point just like in failover cluster.
But you have to pay for SRM and Vsphere replication.
