I'm currently evaluating vSphere4 and i copied some VM from 3.5.
Everything work fine - until I've upgraded the VM Tools. After that, every VM (Windows 2003 Server) takes about ten times longer to boot up.
Even the I/O- Performance within the VM seems to be better than under 3.5, this fact does confusing me. And about 15 minutes to startup VM is too long anyway.
Does anyone has a clue about this problem?
