Best practices for managing a VM appliance
Hewlett Packard Enterprise recommends the following guidelines for managing your VM appliance from the virtual console:
Best practices for managing a VMware vSphere virtual machine
Do
Use thick provisioning. (Required)
Use shares and reservations to ensure adequate CPU performance.
Do not
Use thin provisioning.
Update the VMware tools. If VMware Tools show Out of Date or Unmanaged, they are running correctly. These status messages are not a problem, because the tools are available and running. VMware tools are updated with each HPE OneView software update.
Revert to a VM snapshot (unless under specific circumstances, as instructed by your support specialist).
Set the Synchronize guest time with host option in the vSphere client when the HPE OneView appliance is configured to use NTP. HPE OneView automatically sets the appropriate Synchronize guest time with host setting during network configuration. When HPE OneView is configured to use NTP servers, the Synchronize guest time with host option is disabled. If HPE OneView is not configured to use NTP servers, it synchronizes to the host VM clock and the Synchronize guest time with host option is enabled. In this case, configure the VM host to use NTP.
Reduce the amount of memory assigned to the VM.
