Yes, but hardware still matters. Look at virtualization - yes, VMWare and co mostly make it work, but it's slow, buggy and full of vulnerabilities. In short, it's a kludge.
- arethuza 17y agoI wouldn't describe VMWare ESX as slow or buggy.
- rbanffy 17y agoEvery x86 processors, however, is decidedly a kludge...
- JoachimSchipper 17y agoI was under the impression that I/O performance, in particular, was still rather bad. The VMWare forums contain some links to http://vmfaq.com/?View=entry&EntryID=33 http://vmfaq.com/?View=entry&EntryID=33, for instance, which suggests about a 50% performance degradation for most virtualization products. Does this not apply (anymore) to ESX? I imagine it's improved somewhat, but AFAIK it can't match "real iron" speeds. I suppose that only gets worse as you add SANs, SSDs and other fun stuff. As to "buggy" - well, I consider anything with repeated severe security issues to be buggy. Just search for "VMWare vulnerability".
