If you can run a kernel that's been ported to Xen it'll be faster (and more stable, at this point, since that code is more mature than the VT code) than using an unpatched kernel. You also get features like suspend/resume and migration, which are not currently available for unpatched guests. > Is there any performance difference between a Pentium D 3 Ghz with vt > (9xx) and without it (8xx)? No idea... are the specs different in any other way? Remember VT isn't used *at all* when running a Xen-patched kernel, so having VT features enabled will not speed up the performance of that kind of guest. If you don't want unmodified guests, then there's no need to get VT. Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat? And no pedals!
