sorry but no please read
http://wiki.debian.org/DebianKernelPatchAcceptanceGuidelines

pv_ops is the upstream way we enabled them in 2.6.25 and
enhance the existing 2.6.26 base.
what are you moaning?

right but you seem to have zero idea about the x86 upstream git
tree and it's dependencies. the merge of that is out of question
for the upcoming stable kernel.

The save/restore and ballooning patches were applied to the trunk 2.6.26
Debian kernel a few days back, enabling these features for 32 bit
kernels.

Lenny will be releasing with (at most) 2.6.26 and these patches are a
bit too large and intrusive to non-Xen code paths to be backported.

This thread was started to discuss possible ways to get xen dom0 support
into lenny.. this SLES11 patch thingie was one option.

But I guess it's not possible solution.

I only meant that those patches are queued for 2.6.27.

Yeah, I only meant those patches are queued for upstream 2.6.27. I didn't
mean they should be applied to debian xen kernel for lenny.

Like said, this thread was started to discuss about possible options of
getting xen dom0 support into lenny, and I pasted that git link to give a
status update of pv_ops work happening atm.

current best guess is lenny+half.

having seen the lessons of etch+half and with the established procedure
we should start sooner. 4 upstream version after the release as goal.
that would be 2.6.30 if naming stays the same. most probably this
would have much wider xen support including dom0.

there still exists the unofficial waldi's dom0 2.6.18 latest xen branch
based kernels.
