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... -- Best regards, Robert Milkowski http://milek.blogspot.com ___ zones-discuss mailing list zones-discuss@opensolaris.org

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.

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. -- meem ___ zones-discuss mailing list zones-discuss@opensolaris.org

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.

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.
