first off - i personally never used vboxvmservice on vista/2008srvr and therefore do not know whether it is going to work at all. reports have indicated that it is possible though.... there are some hints on the differences between a vista- and a winxp/2003-install in the SUPPLIED DOCUMENTATION, which i would REALLY advise you to re-read carefully.
after a quick glance at your logs and ini-file, allow me to point your special attention to section 9 - "installation & operation instructions":
Open up the "VBoxVmService.ini" file, located in the root directory of your installation.
Adjust the values within to suit your environment:
!!!IMPORTANT!!!
EVEN IF YOUR PATHVALUES OR VM-NAMES CONTAIN BLANKS:
DON'T USE QUOTES ("" or '') WITH THE VALUES YOU ENTER HERE!!!
now take a look at your post and tell me what you see there... seriously guys - i am always taking the time trying to help out, but if i see stuff like that posted here --- stuff that i especially pointed at in the docs --- it's kinda hard for me to bring up the motivation to even follow this thread in the future...
