Yeah, we had several servers that would have made no sense to convert. Usually it’s some quirk/fluke regarding hardware or resources. Some that immediately come to mind is one that had a big fax modem with several phone lines attached(that was a non starter). There was another with a 3TB local storage array, and it was using A LOT of it. I thought it would be crazy to use that much storage on the SAN for just one server.
Some of my favorites were the ones where a vendor claimed that they didn’t “support” their apps running on a virtualized server. The VAST majority of those vendors NEVER send people on site, so I’d just VM their servers anyway. They never knew the wiser. They could easily find out if they REALLY looked around when working remote for support, but I was pretty good at hiding it. Always sure to disable the VM Tools tray icon, that’s a dead giveaway lol. In almost every case, applications would perform BETTER after conversion. It was also fun toying with them when it came to unreasonable hardware requirements. They almost ALWAYS ask for too much for their apps. I’d usually see how much they REALLY used, make it APPEAR they have the amount they ask for, but throttle them in the VM configuration to not exceed ‘x’ amount of resources.
I also thought it odd that VMware never did a version of vCenter for Linux.
