[ QUICK TIP ] One of your ESXi Hosts (Hypervisor) just failed so what will happen to the VMs.

One of your ESXi Hosts (Hypervisor) just failed so what will happen to the Virtual Machines running on it? Okay, the VMs will definitely power off and if vSphere High Availability (HA) was correctly configured in the cluster nothing should happen to the VMs. The VMs will try to restart on another host, but there are things that will stop a Virtual Machine from being restarted on another Hypervisor like “restart policy”. 

If HA is enabled but the Virtual Machine restart policy is disabled then the VM will not be restarted on another host ignoring the HA master election process. Also, an incorrect Admission Control settings & resource availability on the host will stop the VMs to restart on another ESXi. Hey guys, the key thing to remember is that HA will not trigger a vMotion.
