Re: Tape and VM?

OK, I'll play devil's advocate here. While I get your point about legacy I/O, even KVM supports PCI and USB pass-through with some effort. I would think that would cover a fair bit of legacy kit (excluding ASI cards, proprietary daughterboards, and other such horrors which couldn't even be physically connected to more modern kit). I once had a VM talking to an ancient PCI Fax modem for example. No idea why, but it was the only card I could ever get to send reliably through our supposedly 40+ year old telecom wiring.
None of that gets to the real point of the article though. Keeping aging servers and applications around can (and likely will) end up costing way more than a rip-and-replace. I know how awful those experiences can be first hand, but isn't keeping stuff around that's difficult to impossible to replace/repair the IT equivalent of playing Russian roulette? If you're an old hand who knows that box inside and out that's great, but what happens if you get hit by a bus? I guess I just read the article less as "virtualization will solve all your problems" and more "people have come to expect access to modern tools for backup/migration/failover so get your old shit in order". Do you want to deal with the disaster when lady luck decides, or do you want to at least get to plan for the pain of migration?
