[zones-discuss] solaris10 brand project proposal
Posted:
Apr 23, 2009 9:02 AM
|
|
I would like to propose a project to be sponsored by
the zones community. This project would create a
solaris10 branded zone for use on OpenSolaris.
We will use the BrandZ infrastructure to deliver a
solaris10 brand. This will be provided as an adoption
and compatibility aid to enable users currently
running S10 to easily adopt OpenSolaris while also continuing
to run their S10 software within branded zones.
As with the existing solaris8 and solaris9 brands on Solaris 10,
this project will provide a 'physical to virtual' (p2v) capability
that can migrate an existing S10 software stack on a physical
system into a solaris10-branded zone running on a OpenSolaris system.
In addition, the project will provide a 'virtual to virtual' (v2v)
capability that can migrate existing native S10-based zones into
solaris10-branded zones running on a OpenSolaris system.
This brand would be available on all architectures that run
OpenSolaris (sun4u, sun4v and x86).
We've started working on this in the zones team. It will be
hard for the community to actually contribute to the emulation layer
since the Solaris 10 source code in not open sourced, but we
would like to have the full source for the brand and its
emulation be open source and part of OpenSolaris. The community
could easily contribute to the p2v & v2v code as well as provide
feedback on the brand itself.
Thanks,
Jerry

Sounds like a necessary brand and a good idea.
I admit, I'm curious what needs to be emulated? I would think that
Solaris 10 zones would work just fine under OpenSolaris as native
branded zones.

>From the networking side at least, there's a fair bit of work here. In
particular, there are a number of features that have been removed
(e.g. implicit VLANs) or have changed dramatically (IPMP, GLDv3) and will
require some cleverness (possibly significant cleverness) to preserve the
S10 experience when run atop a Nevada kernel.

Ben,
There are a few differences in the kernel between s10
and opensolaris. Right now we're emulating 10 system
calls and only running shared stack. We haven't yet
started to scope the work for exclusive stack but with
crossbow in opensolaris, that will be a big area of
emulation. Once the project goes up, people can see
the exact syscalls we've emulated so far. Plus, since
S10 and opensolaris are under active development, the
kernels could continue to diverge and we might need
to emulate more syscalls over time.
Thanks,
Jerry

Hi! Count on our community to help with this. We have experience working with Solaris 8 & 9 zones inside Solaris 10, and using the migration toolkit provided by Sun. Best regards, HeCSa.

+1 !!!
Do you plan to provide S10 brand zone on top of Solaris 10 too?
This would much simplify patching and reduce downtimes when S10 zones
are being used under Sun Cluster. Actually when it comes to patching
S8/S9 branded zones are currently easier to deal with than native
zones... IIRC I saw a project proposal to address it - I'm not sure if
it is a separate project or is it under this project or if I have
imagined it...

There is currently no plan for implementing this in s10.
However, there are a couple of other projects which should
make a big improvement in patching zones on s10. One is:
PSARC/2008/644 Parallel Patching of Zones
which was not an open case
and the other is:
http://arc.opensolaris.org/caselog/PSARC/2009/173
PSARC/2009/173 Fasttrack for turbo-charging SVr4 package install.
Thanks again,
Jerry

Belatedly, a big +1. Jerry, if you have not already, I can take this
to the OGB for creation.

Thanks Dan. I think we have enough votes now. I will
see about getting this set up this week. If I need a
hand, I'll let you know.
Thanks again,
Jerry

The project page for this has been set up at:
http://opensolaris.org/os/project/s10brand/
I'll work on getting this populated and linked to
the zones community page. We're going through
the internal review right now to release the code
we've already written for this brand. Once thats
done, I'll get the code posted as well.
Thanks,
Jerry
