I have recently p2v'd our VCenter server and taken a snapshot of it. It's not doing anything fancy like HA or DRS, just simply VM management. After doing this I upgraded the Server OS from Windows 2003 to 2008, now the vcenter service wont start (v5.1), which isn't entirely surprising as I have always had issues like this and have gotten it working with different and unique fixes each time, for example this was that last fix that worked, post p2v it stopped working again (a delicate service no doubt)...
But now, it wont start, IE but it's a new and unique problem once again, because it wont fail, it just gets stuck on starting. And if you watch the vpdx service, it keeps the cpu utilization at around 25% and RAM keeps looping from 20mb to 75 and back down again.
Any tips or tricks or "rituals" to get it working again, or was I too bold expecting that it would continue to run after the OS upgrade? I can always just revert the snapshot, but it would be nice to get it starting as all of its other many... many service dependencies are running...which is weird.
