Most of the 3.6 features require el7, so new features can only be added there. 3.5 will be maintained for as long is needed/requested, but eventually we have to move on. After all, hypervisor hosts are supposed to be in full control of oVirt so you shouldn't care/modify them too much. We always support only the recent minor releases, so in this sense we did drop <=6.5 in 3.5 already; you can only run on 6.6, 7.0 and 7.1.

+1 also take a look at the results of the user survey: most users use el6 so even the discussion about "dropping support" will make people uncertain how long they will be able to use el6. me included.

I cannot understand these conflicting statements. if any component of vdsm needs to run on el6, el6 support cannot be dropped, this [among other] includes python version and other infra modules, packaging included. a possible sensible solution is to continue maintaining 3.5 for gluster on el6 with possibly new features, and have master free of el6 for all dependencies. dropping el6 from 3.6 should have been early in development cycle to allow proper testing. the gluster issue should have resolved even before the 3.6 cycle. > > > > >> > >>> > >>>> > >>>>> > >>>>>> > >>>>>> Regards, > >>>>>> Dan. > >>>>> > >>>>> ___ > >>>>> Devel mailing list > >>>>> Devel@ovirt.org > >>>>> http://lists.ovirt.org/mailman/listinfo/devel > >>>> > >>>> ___ > >>>> Devel mailing list > >>>> Devel@ovirt.org > >>>> http://lists.ovirt.org/mailman/listinfo/devel > >>>> > >> > >> > > ___ Devel mailing list Devel@ovirt.org http://lists.ovirt.org/mailman/listinfo/devel

This was only because downstream gluster + vdsm would continue to be supported on RHEL 6. is there an expected date at which new features would be .el7 only, so .el6 support can be dropped upstream? there is no reason to drop anything from upstream if it is to be supported. it will only create overhead for product support. we have long on going effort is to reduce diff while you keep pushing for fork. it always turned out to be incorrect decision. please learn from experience. I asked when they plan to drop support, so we can drop unneeded code. I do not understand. unneeded code from where? you wrote "upstream" which suggest you keep it "downstream". Had you written from "product" / "vdsm" I would not have responded. vdsm master (aka 3.6) should work or should not work on el6? [downstream/upstream/customized] should work, for gluster does it mean that 3.6 cluster level will not be supported at el6? for virt side, yes. does it mean that 3.5 will be supported long cycle for el6 to bridge the gap for these who do not upgrade to el7? no new features for el6 (z-stream only)? yes, that's the plan - no new features for the virt side for .el6. my question was when this would be true for the gluster side.

I do not understand. unneeded code from where? you wrote "upstream" which suggest you keep it "downstream". Had you written from "product" / "vdsm" I would not have responded. vdsm master (aka 3.6) should work or should not work on el6? [downstream/upstream/customized] does it mean that 3.6 cluster level will not be supported at el6? does it mean that 3.5 will be supported long cycle for el6 to bridge the gap for these who do not upgrade to el7? no new features for el6 (z-stream only)? > > > > >> > >>> > >>>> > >>>> Regards, > >>>> Dan. > >>> > >>> ___ > >>> Devel mailing list > >>> Devel@ovirt.org > >>> http://lists.ovirt.org/mailman/listinfo/devel > >> > >> ___ > >> Devel mailing list > >> Devel@ovirt.org > >> http://lists.ovirt.org/mailman/listinfo/devel > >> > > ___ Devel mailing list Devel@ovirt.org http://lists.ovirt.org/mailman/listinfo/devel

This was only because downstream gluster + vdsm would continue to be supported on RHEL 6. is there an expected date at which new features would be .el7 only, so .el6 support can be dropped upstream? there is no reason to drop anything from upstream if it is to be supported. it will only create overhead for product support. we have long on going effort is to reduce diff while you keep pushing for fork. it always turned out to be incorrect decision. please learn from experience.
