Under some circumstances such as Virtual Machines failing to start due to resources constraints, there could be the need for a rapid calculation of the total memory in use on an Oracle VM Server / Private Cloud Appliance Compute node.
And one might want to to know the total number of vCPUs assigned to all VMs running on the OVM server or PCA Compute Node. This is particularly useful to quickly determine if there is overcommit on the number of virtual CPUs provisioned compared to actual cores on the virtualization server.
This note briefly explains how to do that using a single line command.
