Put one of the hosts in Maintenance mode, stats update does not ignore host in maintenance mode and the free vCPUS is still 48.
It should be 24

    VCDriver - Ignore host in Maintenance mode in stats update

    The VCDriver during stats update checks only for connected hosts.
    However hosts which are in connected state to the Cluster can
    be set to Maintenance mode.
    The cluster does not boot instances to hosts which are in
    maintenance mode.
    Hence the VCDriver should check for hosts which are in
    maintenance mode and ignore them for stats update.
    VISDK API returns True for the property inMaintenanceMode for
    Hosts which are in maintenance mode
