Xen and Kernel 2.6.25

Xen and Kernel 2.6.25

[Crazy]

Some question.
Can I install Xen-3.2.1 with 2.6.18-xen kernel... to my Dom0
and without HVM, starting a debian(DomU) with kernel 2.6.25 from kernel src 
and compiled with all XEN port / features ?

or i need to use the vmlinuz-2.6.18-xen  to all my DomU ??


Thanks
Crazy

I don't think you'll be able to compile 2.6.25 DomU kernel from
vanilla sources (= kernel.org + xenbits.xensource.com). That's because
the changes have not been ported to anything beyond 2.6.18. However,
you might find that suitable patches/packages have been created by
individual distributions. So for example:
$ apt-get source linux-image-2.6.24-18-xen
gives me 'xenified' linux sources on my Ubuntu 8.04. I don't know if
that's good enough for you (you asked for Debian + 2.6.25, this is
Ubuntu + 2.6.24), but it should get you started.

Recent mainline kernels (including 2.6.25) have domU support.  It's
not feature complete but it should be useable.  (Last I checked
save/restore and ballooning weren't supported, but work in this area
is continuing apace.)

Really nice.

I try to use 2.6.5 with the domU support, and it´s working!
The only thing that isnt working its the vnc. I think because 2.6.25-xen, 
doenst have frambuffer for xen support yet
Its a task for 2.6.26 perhaps

see in http://wiki.xensource.com/xenwiki/XenParavirtOps
-----------------------------
# eatures in 2.6.25:

    * x86-32 support
    * SMP
    * Console (hvc0)
    * Blockfront (xvdX)
    * Netfront

# Queued for 2.6.26:

    * Balloon (contraction only)
    * paravirtual framebuffer + mouse (pvfb)
    * 2.6.26 onwards will be PAE-only

It's already in the 2.6.26 tree.  You could clone Linus's git tree, or 
download a tarball of 2.6.26-rc6 if you'd like to try this out.

Cheers,
Mark

Yes, of course. Sorry, I was completly stuck in my little world cloned
from xenbits :).

You can use a different kernel in each domU, it's independent of dom0 kernel 
version.
