What happens if an ESXi host that is running the vCenter Server virtual machine experiences a power outage?

vCenter Server is running in a virtual machine that is part of a vSphere HA and SDRS cluster. The vCenter Server virual machine has been tested and can successfully migrate with vMotion between all ESXi hosts m the cluster DRS is configured for partial automation.

What happens if an ESXi host that is running the vCenter Server virtual machine experiences a power outage?

A.
All DRS cluster operations will be unavailable until the failed ESXi host is brought back online.

B.
vCenter Server will remain offline, but all virtual machines on the remaining hosts will continue without interruption.

C.
This situation cannot occur, because vCenter Server cannot be installed on a virtual machine in a vSphere HA cluster.

D.
vSphere HA will restart the vCenter Server virtual machine on another host

    This question relates to questions 1310, 1475, 258, and 335. Essentially it comes down to this:

    If HA is running (as will be mentioned in the question) the answer will always be “vSphere HA will restart the VM on another host…” Without HA in the equation of the question then it will simply be “vCenter will remain offline, but all VM’s will continue without interruption…”.
