Yes, we welcome this step forward towards a full Xen merge in LKML - it is
a critical move for Xen to be sustainable as part of Fedora. It is, however,
only a partial solution at this time, so we can''t actually make any
real use
of it in Fedora yet. At minimal we need architecture coverage - x86_64 in
particular. Second we need support for using a single bzImage for both bare 
metal and Xen - the initial merge still produces separate binaries for Xen.
Once those two are complete we''ll be able to use the mainline kernels
for the
guest. Focus is then on also merging Dom0 bits - with that we''ll have a
much
more sustainable solution.

Regards,
Dan.

lguest will be compiled as module in new fedora kernels ?

We''ve no plans to include lguest in the Fedora kernels at this time.
Again
it is only available for i386. Its current purpose is as a means for kernel
developers to research & experiment with virtualization ideas - not for end
users to put into real world use - there is Xen & KVM for real world use in
production. There are also no tools for managing lguest instances since it
is mostly targetted for kernel hackers. Signs are that some of the ideas 
from lguest may merge into KVM allowing it to do paravirt without hardware
support - if this happens it would be a better choice for Fedora that using
lguest directly since we''ve already got management tools around KVM. So
we''re basically intending to ''wait & see'' wrt to
lguest and not enable it
in Fedora at this time.

One of the biggest restrictions that lguest maintains is that it is
guest and host kernel versions are tightly coupled - for the stated
purpose of lguest completely appropriate, but definitely limits is
usefulness as a replacement for pv Xen. So: even if lguest was in
Fedora, you''d probably not get from it what you''d like to get
from it.
