>> Under %post section of RHEL5 installation haldaemon and messagebus service is stopped. 
Later after reboot these services are running. But under %post they are stopped.
If we add commands to start (/etc/init.d/messagebus start;/etc/init.d/haldaemon start) it in %post then they get started. But they are not running by default.

rhnreg_ks has the below code which fetches the information and decides whether the system is fully virt or para virt or a physical host system

..snip ..
    bus = dbus.SystemBus()
           device_obj = \
               bus.get_object('org.freedesktop.Hal',
                              '/org/freedesktop/Hal/devices/computer')
           device = dbus.Interface(device_obj, 'org.freedesktop.Hal.Device')
           vendor = device.GetPropertyString('smbios.bios.vendor')
..snip ..

As messagebus and haldaemon are stopped in post , rhnreg_ks is unable to get the required information and hence the system is treated as a host system.
