and plugin…

We having been using VMware here at work for quite a while now. We have the full setup, and it all works really good. But we have had a very annoying problem with VMware convertor for some time now. It migrates virtual machines to ESX server from Virtual server just fine. Also handles Physical-toVirtual great as well. But after you get the VMs on to your ESX box, and you want to reconfigure them, or move them back to virtual server, you can't. You get this error "unable to determine guest operating system". After search the forums and such, we found little advice. But a small line at the bottom of a discussion board on a third party site had the answer. "unplug your usb drives". What? Bullshit. That can't be it. I took a look around my computer, and sure enough I had a USB floppy plugged in. I removed it and tried again… It worked.

So. If you use VMware convertor… UNPLUG YOUR USB DRIVES BEFORE RUNNING!
