Pavel,
Please correct/enlarge me if there's anything missing/incorrect.

Hi,
the ongoing merge of OpenVZ-based lightweight virtualization into
mainline Linux seems to be progressing nicely and I have a few questions
about it:
- How usable will net namespaces be in 2.6.25? I'm especially interested
in assigning a real hardware ethernet device to a VE.
I guess some network namespace stuff is NOT completed in upcoming 2.6.25
(a lot of stuff done, but not finished)
For 2.6.26, it will be more-or-less working, with just a few exceptions
such as conntracks and IPv6 -- maybe.
- Will there be an OpenVZ patch or against 2.6.25?
As of now we do not plan to have one. Porting to each mainstream version
is too much work to do -- instead we concentrate on
(1) merging stuff to mainstream
(2) supporting our stable kernels
(3) stabilizing 2.6.24 (for now)
- Do you expect net namespace/virtualization work to be completely
merged in 2.6.26?
As said before, we guess that network namespaces will be more or less
useable in 2.6.26.
- Which OpenVZ features will not make it to mainline in the 2.6.26
timeframe?
A lot. Network namespaces is just one piece of a pie.
To paint in big strokes: resource management and live migration are
still on our todo list.
Resource management: some stuff is in -mm kernel, need to add much more.
Will work on that after finishing with net namespaces.
Live migration: this is much more far perspective, we haven't even
started to discuss that seriously on containers@ list.
Some of the questions above probably can't be answered without guessing,
but a good guess is better than no information and I'd appreciate any
status update newer than the OpenVZ blog entry from 2008-01-26.
Thanks,
Carl-Daniel
