There's no clear plan here yet. To date the list of missing features is still too long for me to drop my resistance to that step, and the rate of regressions introduced upstream is still too high. Nevertheless I'm considering the move more actively than I did sys a year back. But that move would - for both above named reasons - require quite a bit of resources being available, which I can't currently foresee to happen. In any event - tying the move to pv-ops to the dropping of a separate Xen kernel is questionable: As long as the PV spin lock infrastructure can't be uniformly enabled due to having performance effects on the kernel when run on raw hardware, we will be in need of a separate kernel anyway. The good news here is that PV spin lock work has been resumed upstream recently, after having been stalled for a couple of years.

So then why did you ask when we would switch? Or did I wrongly imply you want us to switch, and you really asked fearing we would? Jan -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-virtual+owner@opensuse.org

Hi all,

It could be just my perception, but i've got the feeling that more and more attention is given to KVM, and i wonder if this is intentionally?

For instance, on http://doc.opensuse.org/ it is about "Virtualization with KVM" in htmp, pdf and epub, while not a single word about XEN or LXC... Intentionally?

I don't think it is intentional. AFAIK, the docs come from the SLE docs, and seems no one has added the Xen ones to doc.opensuse.org https://www.suse.com/documentation/sles11/book_xen/?page=/documentation/sles...

I got quite some paravirtualized servers, this is seriously worrying me. And as a long term XEN user, should i start looking for an alternative distro in case SuSE is going to drop XEN?

There are no plans to drop Xen support. SUSE is one of the largest contributors upstream (2nd in upcoming Xen 4.3 [1] release) and we will continue to provide Xen packages in the future. openSUSE13.1 will have Xen 4.3.x, where the new xl/libxl toolstack will be default and xm/xend is deprecated. Work continues on the Xen front within SUSE... Regards, Jim [1] http://wiki.xen.org/wiki/Xen_4.3_Acknowledgements -----Original Message----- Thanks Jim, for re-assuring. Big sigh of relief. Yeah i know that SuSE has been a mayor player in the XEN area: I was told that "other" distro's have been using your patches for many years, until they decide to switch completely to KVM. Further down the thread, it is mentioned about the suse-specific kernel patches. Is that still the case since XEN became part of main-stream kernel? Excuse me my ignorance, since i only used openSUSE or SLES for dom0 and mostly for domU, and only used distro-supplied kernels.
