But with paravirtualised Linux, with a recompiled kernel, you have better performance.

Thanks for that. What about a VT-supported cpu to do the
para-virtualization
instead of full-virtualization? which one is better.
I've AMD PV and Intel VT here and from my point of view the VT are much
better (and that's no matter if they're AMD, Intel or from Mars...),
because you can install an OS "out-of-box" to that server.
With PV you're limited to Linux and to special kernels.  And the
arguments Mats brought up may be right, but as long as you do normal
daily business on such a server (file-server, webserver, etc...) at VT
machine would always be the better choice.

Sure, with VT (in my view obviously preferrably from AMD ;-) ) you have
ALL the possibilites, rather than just half of them. I should have said
so in my post.
