 Still, by giving so much capabilities to the guest you're basically
turning vserver into nice-managament-setup, and all the security goes out
the window (not that my setup with Xorg in guests is that secure, I too
like having clean host and ability to easily backup/move all the
functionality to other machines).

 With VMware Player I just had to setup networking once ( I created two
setups, one NATed and the other bridged ), and now I'm not touching
anything, every new image just uses one of those and that's it. And I don't
even use CAP_NET_RAW on the VMware'd guest.

 They can, and do, check ML archives.

 Since I'm using mainly linux under vserver, the only thing I want from xen
is ability to test new kernels. One can imagine such setup -
you boot with ~32M xen monitor, rest of the memory goes to main vserver
host, and you leave ~32M/~64M haning exactly for such a purpose (OTOH, as
balooning driver works quite nice under linux and OK for netbsd, you could
use all the ram for production, and when the time comes for testing new
kernel - you dynamically shrink your production image, boot up testing, and
if all goes well, you switch them.
