xen-2.0 + linux-2.6.15?

xen-2.0 + linux-2.6.15?

[Nils Toedtmann]

I have a very stable xen-host with several domUs (uptimes > 300d). 

It's still 2.6.11.x + xen-2.0 and now i'd like to upgrade it to
2.6.15.4. I have to do that remotely, and xen-2.0 was absolutely ok for
me (rock-solid!), so i'd like to stick with xen-2.0 for now. But the
last Changeset of the xen-2.0-testing hg tree is 3520 from 2005-12-28,
and it still wants linux-2.6.12.

Do i have to choose between 2.6.12.x+xen-2.0 and 2.6.15.x+xen-3.0? 

What about a maintenance release 2.0.8 for linux-2.6.15 or upcoming
-2.6.16?

/nils.

At the moment you have to make that choice. It would be great if 
someone upgraded the 2.0 kernel, but the core developers are busy with 
3.0.

That's a choice between two evils ... any experiences comparing
stability of 2.0 vs. 3.0? (Of cause there is no xen-3.0.x system with
uptime>90d ;-)

Comprehensible. So no xen-2 release on the roadmap? Then i'll have to
move to xen-3, too many sec issues with < 2.6.15.4  :(

/nils.

ps: xen is great, thank you for this wonderful piece of software!

In fact the current 3.0 stable release (3.0.1) uses 2.6.12 too. The 
unstable tree uses 2.6.16-rc5. We'll probably do a 3.0.2 release around 
the time of 2.6.16-final. Plenty of people have been beating up on 3.0 
and even using it in production use -- I think its stability is pretty 
good (but as you say, we have no really trustworthy objective metric 
for measuring stability relative to 2.0 right now).
