hi:
i search the forum, and i can't believe it. all kind of shutdown problem appear from 2005. and at least two of them are not solved yet.
1. make sure vm shutdown before host shutdown/reboot.
2. can not shutdown the locked windows os
i alreay write script to solve the first issue. it is so easy and i don't know why vmware refuse to do that. esxi 4.0's "shutdown.sh" and "reboot" just don't care the safety of vm.
vmware said the second issue is microsft fault. but every modern os in physical machine will do graceful shutdown when user press "power" button. i don't know why vmware can not emulate that kind of shutdown. with that acpi shutdown you even don't need vmware tools installed. and every vm can at least have a safe shutdown.
it's funny that vm can have all kind of advanced functions like motion,HA,FT, but can not do a safe shutdown.
