My client would like to protect against a hardware failure on a single host running 2 VMs by using 2 hosts configured with HA. If vCenter is running as a VM on a host with the 2 production VMs and the host fails, will the other host be able to recover the work loads automatically, or will the someone need to access the running host directly to start vCenter and the 2 production VMs?
Obviously 3 hosts would be better, but budge doesn't allow. Shared storage, adequate resources to run 3+ VMs on each host. vSphere 5.5 Essentials Plus Kit
Thank you.

That is going to work.
As per your post you have two hosts
H1 :::VM1,VM2 & vCenter VM which is managing this HA cluster
H2::Failover hosts with no any VMs running
Please confirm above setup.
As you have enough resources, this will work fine. In case of host failure, HA continue to work, You will have to face minimal downtime as vSphere HA will restart these VMs (automatically).
As vCenter VM also will have downtime in case of failure, you can not login to vCenter/manage HA cluster until all vCenter services are up and running. vCenter is used just to manage the HA cluster, rest is at host level.

Hello Freind,
Welcome to the community.
Seen your Environment and as i tested it with my environment already. the HA will works automatically without any heck .
vCenter Server is only used to configure VMware HA, Once you have configured your hosts, vCenter Server installs an HA Agent (which is correclty called the FDM Agent - Fault Domain Manager Agent or AAM ).
So no issue go ahead and develop the thing as you want .
Thanks
Thanks for the confirmation.
