            There is another issues needed to be fixed before pushing 0.9.4
        The "lock_manager " in qemu.conf still uses old default value .
        When it is uncommented,   it will lead to qemu driver 
initialization failure:

        20:47:45.227: 23830: error : virLockManagerPluginNew:147 : 
Plugin /usr/lib64/libvirt/lock-driver/fcntl.so not accessible: No such 
file or directory
        20:47:45.227: 23830: error : qemudLoadDriverConfig:457 : Failed 
to load lock manager fcntl
        20:47:45.227: 23830: error : qemudStartup:540 : Missing lock 
manager implementation
        ...
        20:47:45.227: 23830: error : virStateInitialize:846 : 
Initialization of QEMU state driver failed

        I proposed a patch that needs an ACK:
