Hi Mark,
I am trying to do this on a desktop. I was hoping that since Xen seems
to be more intimately tied into the kernel
it would give me better performance than VMWare and VBox which only add
drivers to speed up things.

running a stock linux kernel vs a xen'ified one for dom0
is much better. The linux dom0 kernels are (or at least
have been) very old since they haven't, to date, pushed
dom0 support into the upstream linux kernel.
VBox has *much* better desktop integration. I use it with
a dual headed system where I run a VM on one screen in full
screen mode and the host system on the other screen.
Xen has poor framebuffer support compared to VBox and vmware.
We don't even support a virtual frame buffer in solaris for
Xen today (doesn't provide a lot off value to have it).
Unless you doing constant local builds and are impatient,
you won't notice any performance differences between VBox
and Xen. And even then, you will probably me limited by your
disk.

Hi,
I want to run Opensolaris as a domU on my linux box (ubuntu 9.04).
Is this possible and if yes, will it offer better
performance than VirtualBox and VMware. BTW, I don't want to change
distros, so it should be doable with Ubuntu.
What problem are you trying to solve?
If you are running it in a desktop environment,
you should use vbox.
If this is a headless server and you want good MP
performance and close to metal performance on
>= 1G NICs, you should use PV guests on Xen.
