[OpenIndiana-discuss] What advantages of KVM over Vbox

Back in October when I was trying to get this working it was suspected that issue with the T7700 was the lack of ept and vpid. Possibly lack of vt-d too. 

Given all the variations I think it would be more reliable and a better community experience to report known working CPUs than pointing to lists like the VTList page at Intel. Of course, that implies someone volunteering to be a gatekeeper to collect, collate, and report that information, and keep it up to date.

However that processor doesn't work for OI with KVM, at least not when it's in a Thinkpad T61p. It would sorta try to work, but any guest OS other than OI wouldn't boot the installer.

>> If you are going with Intel then make jolly sure to read the small type before committing. I assumed the quad core Q8200 I purchased a couple years back would have VT-x support (quad core Intel CPU, c.2009 right?), but incredibly it doesn't. One of the reasons I buy AMD now (okay, no AMD support for KVM on OpenIndiana yet), these sort marketing tricks are a complete pain in the butt.
