Yes, rather a lot (see signature) :)

Fedora's support is probably the easiest to get along with but
personally I stick with Debian because I know Debian best.  If
Fedora is something you're comfortable with then probably that is
the way to go, but it's possible on any distro as long as you're
comfortable compiling kernels.

Out of all the above it will be ease of use and manageability that
will be the key, I believe.  Xen has problems integrating with the
main Linux kernel (as in, it's not part of the kernel tree and
won't be anytime soon), whereas lhype (now know as LL) is already in and
is getting more features every day.  It may well catch up soon but
right now it is a definite work in progress and not something you
could base a production service on.

VMWare is very nice if you can afford it.  It is currently far too
expensive to use for hosting purposes, and I imagine it will stay
that way.  For personal use it's great but I think that they will
keep things as they are purely to maintain a level of interest.

KVM looks pretty good as long as you have the VT extensions, but
it's still quite slow, without much amnagement tools,  and so not so
useful for hosting.  Still good for personal use and for testing
things though.
