[Xen-devel] What is the official source for the pvops kernel?
I want to download the latest (2.6.38) pvops kernel, and I''m trying to work out where I should get it from. There seems to be a number of potential sources at kernel.org referenced from the Wiki, but depending upon the kernel version you should go into jeremy''s or konrad''s personal git tree. I''m a little uncertain which one I should use, particularly since the only reference I can find to the source is a wiki which anybody can edit. Also konrad''s version which is referenced from the wiki is for 2.6.38-rc7, but 2.6.38 has now been released. Is there an official repository for the pvops kernel or is the official way to get it to download from an individuals personal git repository? thanks, Anthony _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

It might be a week before I can update tree. You can start using devel/next-2.6.39> > Is there an official repository for the pvops kernel or is the official way to get it to download from an individuals personal git repository?First of, 2.6.38 is unstable. We haven''t completed all the up-porting effort and there are bounds to be bugs. So when you run it, please do report the bugs you are seeing. For right now there are two git trees. The official vaniall 2.6.38 which can: - Boot Dom0 - Boot DomU - Can boot PV and HVM guests with the latest xen-unstable.hg tree and the latest QEMU (which has built-in backend drivers). The 2.6.38 in my tree(git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git) has the things mentioned before, and then: - Can be used with Xen 4.0 as it has now three backends: pciback, netback, blkback. - Can be be booted with Xorg (radeon and nouveau) if the card is PCIe. - Has gntalloc allowing domain-to-domain pages to be shared. - Lots of bug-fixes. - And infrastructure add-ons (backend, P2M, M2P). In short, it has all of the patches that just went in 2.6.39-rc0 and then some more. For the details look on LKML for ''[GIT PULL]'' from me. So if you want the "stable" one use the 2.6.32.32 that Jeremy just released. If you are more adventurous, try out the devel/next-2.6.39 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

If not, could you explain this a little more.> > The 2.6.38 in my tree(git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git) has > the things mentioned before, and then: > - Can be used with Xen 4.0 as it has now three backends: pciback, netback, blkback. > - Can be be booted with Xorg (radeon and nouveau) if the card is PCIe. > - Has gntalloc allowing domain-to-domain pages to be shared. > - Lots of bug-fixes. > - And infrastructure add-ons (backend, P2M, M2P). > > In short, it has all of the patches that just went in 2.6.39-rc0 and then some > more.

I wasn''t sure what the root cause was (I upgraded from 3.X to 4.X Xen at the same time) so I tried 2.6.38-rc7 to see if it was Xen or the kernel and no longer got the panic, so continued with that kernel version. I was under the impression that 2.6.38 would be a stable version, but not it appears not. Is there a version later than 2.6.32 that I could use a stable? thanks, Anthony. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

If you want a dom0 kernel newer than 2.6.32 you can try Konrad''s next-2.6.39-rc0, obviously not stable but your best bet. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
