Vmware Autodeploy with host profile not work

HI All,

Im preparing VDCA 510 and I'd like to ask about the Auto Deploy with host profile. My lab consist of two ESXi servers version 5.0 and vCenter x 1. The syslog server, network core dump service and Autodeploy service are installed to vCenter.

i Follow below link to perform the lab to test bed Auto deploy and host profile.

Unfortunately, the configuration also missed after reboot the server, it didn't write anything to the disk. I followed above link to create the host profile after staged the first auto deployed server as reference host. Then, created the second time deployment rule and applied the host profile created by first time. All of the configuration applied to esxi host in second time, but it didn't saved anything to disk after reboot.

Any configuration I missed? How to make these configurations created by host profile can be saved as permanent for auto deployed esxi host?

it makes me confused and spent lots of time to troubleshoot. Hope anyone can help me to fix it? Many Thanks!
