B.1 Best practices for managing a VM appliance
HP recommends the following guidelines for managing your VM appliance from the virtual console:
Do notDo
• Use thin provisioning.• Use thick provisioning.
• •Use shares and reservations to
ensure adequate CPU performance.
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 If VMware Tools show Out of Date or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 HP OneView software update.
• Revert to a VM snapshot (unless under specific circumstances, as instructed
by your authorized support representative).
• Set the Synchronize guest time with host option in the vSphere client when
the HP OneView appliance is configured to use NTP. HP OneView
automatically sets the appropriate Synchronize guest time with host setting
during network configuration. When HP OneView is configured to use NTP
servers, the Synchronize guest time with host option is disabled. If HP
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.
