Hi Marcelo, 

Reserved size means can’t be allocated to Apps(VMs), it is reserved by host, and decided by hardware.

This capabilities only show host’s capabilities, there will be another libvirt API to report how many bytes can be allocated to VM per cache bank.
Still working on it.

Best Regards

    What reserved means again? 
    Some field should include how many bytes are CAT allocatable 
    at this time in the L3 socket.
    (So libvirtd functions properly with other applications).
    This is required.
