xyz MHz reserved for vCPU in OVA Templates

Hi all,

any chance you can put some light on "reserved MHz" part that is added in brackets when describing number and speed of vCPU cores for particular OVA template? I understand number of vCPUs and speed but I don't have a clue what "xyz MHz reserved" means. Here is one example from OVA template for CUCM 8.6:

vCPU Cores

2 (with 800 MHz reservation)

Following page is just one example containing "reserved MHz" part: http://docwiki.cisco.com/wiki/OVA_Template_Details_for_Unifed_CM_Release_8.6

Tenaro

That's really a VMWare concept and you can find the definition by searching VMWare's site

Reservation

Reservation specifies the guaranteed reservation  for a virtual machine. The server allows you to power on a virtual  machine only if the CPU and memory reservation is available. The server  guarantees that amount even when the physical server is heavily loaded.  The reservation is expressed in concrete units (MHz or MB). When  resources are not used, the ESX Server host makes them available to  other virtual machines.

For example, assume you have 2GHz available and specify a reservation of 1GHz for VM1  and 1GHz for VM2. Now each virtual machine is guaranteed to get 1GHz if  it needs it. However, if VM1 is using only 500MHz, then VM2 can use  1.5GHz.

Reservation defaults to 0. It is often a good idea to specify a reservation to guarantee that the necessary CPU or memory are always available for the virtual machine.
