[CentOS-virt] Virtualization & IaaS DevRoom at FOSDEM (closes Nov 18th)
Hi all, as last year the Virtualization & IaaS DevRoom is happening at FOSDEM again next year, and the CFP is available at http://www.ovirt.org/blog/2016/10/call-for-proposal-fosdem-2017/ I hope to see many of you there again in 2017.

[CentOS-virt] Resigning as lead of the Virt SIG
Hi all, I wanted to let you know that I feel I need to step down as leader of the Virtualisation SIG. When I originally was approached by KB to do this, it was always clear that this would be a temporary thing until the SIG got going. At the time, only Xen and CentOS folks were involved with the SIG. Since then, we added oVirt and Docker maintainers, have a total of 5 maintainers and built good momentum. There are two reasons why I feel I should step down as leader of the Virt SIG: a) I have been traveling too much and thus did not have the bandwidth to do this job justice in recent months. b) In addition, it would also make more sense for one of the Virt SIG maintainers who is more closely involved with day-to-day activities to pick up this job. I will still be able to help with PR and other items. When I was absent over the last few months, George Dunlap (gwd on irc) did most of the groundwork and led SIG meetings on my behalf, so I wanted to propose that George leads the SIG going forward. That is assuming that none of the other SIG maintainers want to step up. George agreed in principle. In the last Virt SIG meeting, not all maintainers were present, so we couldn't make a formal decision. KB said the following: kbsingh: I think if gwd is ok with it, and people are ok in the SIG, its good for me This means that succession either has to be settled in the next SIG meeting, or by e-mail responding to this thread. I don't think there is any formal process, but I would suggest that the maintainers listed on https://wiki.centos.org/SpecialInterestGroup/Virtualization should have a say either at the next IRC meeting or by replying to this email thread.

[CentOS-virt] Minutes of Jan 27 2015 VIRT SIG Meeting
Hi all, seems we are making good progress. Thank you everyone! * First Xen release via the SIG is imminent (see Xen section) * We are also close to a Docker release (see Docker section) * We also need to look at cross-SIG dependencies to be able to make use of Gluster support in the Storage SIG (see oVirt section) Regards Lars = Attendees = * Lars Kurth * George Dunlap * Sandro Bonazzola * Lokesh Mandevar = Agenda = == Replace audio meetings in favor of IRC meetings, which seem to work better == All agree with IRC meetings ACTION :Send mail to list: If anyone objects, let us know. ACTION: Lars to changeg invite and wiki to reflect IRC meetings always. == Xen Update (George) == 4.4.1 Virt-Sif testing for several weeks now. Everything appears to be working Have a wiki now: covering xend to libxl migration - see http://wiki.centos.org/HowTos/Xen/Xen4QuickStart Jonny has pushed the signed packages Thus, this is the 1st Xen release from the VIRT SIG ACTION: George to send quick mail to the list and write up a blog post. CC publicity@xenproject and KB such that he can cross post to the CentOS blog if he wants to Note: 4.4.1 is still using the new old 3.10 kernel. DISCUSSION: George: do we have a conflict on kernel versions for CentOS 7. For xen we would need to override the CentOS 7 kernel to make Xen work with CentOS 7 Lokesh: there is no kernel requirement for Docker except that the kernel needs to be = 3.10 – this should be a match George: potential issue is that Docker is officially supported in RHEL/ CentOS 7 Lokesh: 3.14 should work for Docker, but needs to be verified. George: before we push to public repo we need to test it. Lokesh: CentOS and Docker are tested with 3.10. For Fedora we test with 3.18. Docker has its own test suite. So covering 3.14 should be straightforward George: would you mind if I uploaded 3.10 and see whether it works? But there may be an issue that we would be missing RedHat backports in CentOS 7 Lokesh: Since yesterday have been doing a daily test for rawhide in addition to the stable branch. I don't think there should be an issue George: Checking understanding that a new kernel is totally OK. Lokesh: As long as we are not disabling standard kernel functionality we are fine ACTION: George upload the latest kernel and coordinate with Lokesh re testing to ensure that nothing breaks = Docker update (Lokesh) = Still on 1.4.1 Yesterday I was talking to Jim and KB re a daily rebuild for CentOS and that should be fine Maybe we will have an additional package Docker-upstream or Docker-unsupported (TBD) I have also been talking to people from Kubernetes and Cockpit re new versions. ACTION: Lokesh to make an announcements on the list(s) and then we can try and make a public release. ACTION: Lokesh to create a getting started wiki page ACTION: Lars to link to any announcements in FOSDEM VIRT SIG presentation = oVirt update (Sandro) = 3.5.1 is upstreamed and released Now we have a bit more time to investigate CBS, etc. We also have credentials for wiki and CBS Sandro: I had asked for some HowTo for CBS / Coogee by mail, which is still unresolved George: has some runes for basic stuff which he can share ACTION: George to create brief howto and share on list/wiki. One of the other issues Sandro brought up is that the Storage SIG now has Gluster support and that he would like to build oVirt with support from Gluster packages in the storage SIG. There may a requirement for QEMU and KVM packages (details needed) from that SIG. George: this will require some cross-SIG coordination that we need to resolve. At the moment we don’t have a way to cover inter-SIG dependencies ACTION: Sandro email storage SIG (via centos-devel) and virt SIG and lay out problem to kick off a discussion. Lars can try and follow up with KB and others at FOSDEM. = Any other business = None ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

[CentOS-virt] Preferred method of provisioning VM images
Hi all, following the discussion on about documentation, I was wondering whether we need to look at a standard way in which we recommend how to provision images for VMs. Am starting this with a Xen hat, but the discussion should not be specific to this. There are a number of options, but all have some trade-offs == #1 virt-install == Advantages: similar to KVM Disadvantages: may cause weird issues / confusion with people switching back to xl. The core issue is that with the current version of xen and libvirt, this only works with xm (when xl is used, this can create some undefined behavior). However as we have seen in some recent threads on this list, people tend to mix which can cause problems. == #2 xen-tools == Advantages: Very flexible. Many other distros use xen-tools, so we have lots of beginners docs that just need to be tweaked Disadvantages: needs porting/packaging for CentOS. Does not work for kvm. Says xen. (Maybe that's an advantage.) We know that xen-tools works with Fedora (see http://blog.xen.org/index.php/2013/01/24/using-xen-tools-on-fedora/), so the porting effort may be small Unknowns: What would be needed to make it work for CentOS == #3 virt-builder (http://libguestfs.org/virt-builder.1.html) == Advantages: supports KVM, Xen and other VM inages. Seems easy to use. - if so, it would avoid xm / xl confusion. Unknowns: Not sure at which level virt-builder integrates with Xen and other hypervisors. It seems to operate at disk image format (similar to xen-tools) . I don't know whether virt-builder is restricted to some hypervisors in RHEL7. Disadvantages: may need porting/packaging for CentOS. It appears as if it will be in RHEL7, so it may just appear with CentOS 7. If not, some porting work may need to be done. == #4 Cloud Image from Cloud Image SIG == We could rely on pre-built cloud images from the Cloud Images SIG. People could just download the cloud image once it's done and customize it, rather than installing / building their own. Advantages: seems easy Disadvantages: coordination with Cloud Images SIG. May not be flexible enough I just wanted to start a discussion about this and ask for input.

I think KB has some too jonludlam Hello lars_kurth gwd: seems we have jonludlam, kbsingh gwd and me so far [14:05] lars_kurth Hi. Before we properly start. Any changes on actions on http://wiki.centos.org/SpecialInterestGroup/Virtualization/Status ? lars_kurth So: no changes then? [14:06] gwd We chatted at the hackathon (with Daniel Barrange there) about libvirt versions jonludlam That was a good session [14:07] lars_kurth gwd: what was the outcome/recommendation? gwd What we said there was that libvirt/libxl driver isn't yet stable, so there's no point doing a choose a version and stick with it thing until it is. lars_kurth gwd: that is what I was afraid of [14:08] jonludlam so libvirt becomes a 'tech preview' until it stabilises? gwd Er, I don't think tech preview jonludlam 'unstable'? gwd More like, Not enterprise. :-) jonludlam ok pasik hello [14:09] jonludlam hi pasik gwd pasik: Hello gwd You know, like the kernel we want to be enterprise and only update every 2+ years. lars_kurth But that is only an issue for libxl, mot xm. Correct? If we are still talking Xen 4.4 that should not be an issue gwd I don't think we want to encourage anyone to use xend if we can possibly help it. gwd We need to transition people away from it. [14:10] jonludlam libvirt is a reasonable transition strategy though gwd Is there a need for enterprise libvirt? Is anyone using that? pasik Hopefully we can get thinks into better shape with xen 4.4 + later libvirt lars_kurth Agreed. How about the needs of KVM, oVirt, ... for libvirt pasik with the current xen 4.2 packages basicly only xend is usable (with libvirt) gwd pasik / euanh: We were just talking about how often to update the libvirt packages. jonludlam ovirt will take a good deal of porting to work with xen lars_kurth jonludlam: correct. But this SIG is not about Xen only [14:11] jonludlam true, but gwd jonludlam: given how much hypervisor detail is exposed by libvirt, how reliable would a libvirt/xend - libvirt/libxl transition go? jonludlam What was said was that ovirt effectively doesn't need anything provided by what we're looking at in sig virt today [14:12] jonludlam gwd, I don't think it would be too bad - it already autodetects whether to use xl or xm based on what's installed, if you connect to xen:// gwd lars_kurth: I think if someone wants to use oVirt+KVM, they can use the core libvirt. gwd jonludlam: Sure, but as we found out, libvirt doesn't try very hard to hide the hypervisor details. [14:13] jonludlam qemu was mentioned in the meeting at the hackathon, but it's totally orthogonal to everything else in the SIG so far jonludlam gwd, but the difference between libxl and xend is much smaller than between qemu and xen gwd Sure; but it may still be a fairly major headache to get stuff to work. lars_kurth kbsingh: any views? I thought you were worried about scope creep in the SIG. lars_kurth Sorry: SIG [14:14] gwd And what actually works well with libvirt+xen at the moment anyway? xm/xl are better than virsh, IMHO lars_kurth gwd: That is probably correct. On the other hand, we don't have an interface into Cloud SIGs until we have libvirt and/or xapi jonludlam the xapi question was a bit clearer after the meetings. Anil and KB talked about an OCaml SIG that the virt SIG could gwd lars_kurth: Yes, but those are not going to be enterprisey either. :-) lars_kurth gwd: so what is the proposal gwd The proprosals are: depend on gwd 1) Choose a version of libvirt (1.2.3 maybe) and stick with it, backporting functionality we're missing. [14:16] gwd 2) Update the libvirt package when there's a new libvirt release until libxl support is mature enough pasik gwd: I use virt-install often to install new VMs pasik gwd: imho it's the easiest way to launch $distro installers in a PV domU [14:17] gwd #2 is easier for us, and will get us all the available libvirt/xen functionality; it's what we favored at the metting at the hackathon. pasik gwd: and virt-install works with xen4.2+xend+libvirt in el6 gwd The only downside is that enterprise customers don't like such frequent updates. jonludlam Daniel B said that #1 would be tricky, as they were refactoring the other bits of libvirt to make the xl plugin easier [14:18] DV We really try to not break libvirt upstream, ideally having the git version run for regtests on libxl would be a good idea gwd DV: Upstream Xen Project already does that. DV * DV agrees with danpb , even in RHEL we rebase to try to avoid backporting gwd Having a new libvirt shouldn't *interfere* with oVirt, virt-install, cc. [14:19] DV gwd: ah, good,

Could you please enlighten me? Konrad, you are absolutely correct. The discussion on XenServer / XenCenter is off-topic really.

No, it isn't. I think we should go through * Round the call for any additional agenda items * Action Updates * Bug tracker * RPM subpackage structure Lars On 20/05/2014 12:02, Jonathan Ludlam wrote: If it's not too late to add agenda items now, could we talk about the structure of the RPM subpackages? In particular, some folks here at Citrix have spent some time fixing up our xen RPM such that the subpackages have a more useful split - for example, there is a now distinction between xen-libs and xen-dom0-libs - where the former has libraries useful in all domains, e.g. libxenstore and libvchan, and the latter has libraries that are _only_ useful for dom0. There are a few other changes that have been made, and I was wondering what the appetite was for convergence, and where the problems will lie if we were to pursue this.

[CentOS-virt] Mailing list policy
Hi all, right now the centos-virt@centos.org mailing list is set up such that all posts by people not subscribed to the list are auto-discarded. This is in line with all the other lists and I propose that we keep things as they are. The reason for this is that traditionally the amount of spam that centos lists are getting was very high. I am not sure this holds for centos-virt@centos.org. It may be worth trying a change to see whether it would be manageable to use moderation of posts by people not subscribed to the list. Input very welcome Regards Lars ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

Re: [CentOS-virt] OpenVZ variant
Andres, thanks for your interest. Could you elaborate what your thoughts related to CentOS 7 and the CentOS virtualization SIG are? I am not sure I exactly understand what you are proposing and it is also not quite clear to me whether there is some overlap with other SIGs (such as the Cloud SIG). I guess the key question I have is whether you are suggesting / considering to use the output of the virtualization SIG as upstream for OpenNode and would want to contribute to the SIG. Best Regards Lars On 03/04/2014 21:30, Andres Toomsalu wrote: Dear Scott, Lars, Currently we already have CentOS 6 based respin (called OpenNode - http://opennodecloud.com) targeted for virtualization - supporting both OpenVZ and QEMU/KVM at the moment - yet it would be possible to add Xen/LXC/Docker support as well - as we are based on libvirt. We are just discussing some ideas how we would like to develop next major version - CentOS 7 based virtualization host - yet we would be really interested for having an open discussion and community based development - if anybody wants to join in or there will be some interest to create something like community CentOS virtualization host project - where we could join. Our current ideas are spinning around CoreOS like (perhaps stateless) CentOS 7 compute host with modern clustering built-in (perhaps etcd) - and we still want to continue to support both containers and full virtual machines on the same host. Hopefully also Docker will be mature enough soon and supporting OpenVZ userland tools - as LXC and OpenVZ share the kernel part and surprisingly LXC seems still not enough mature/feature rich - yet LXC project has existed already quite a long time (which makes me a bit pessimistic predicting on future LXC progress pace). LXC container isolation features still suck a bit (for production systems) and still no live migration feature - yet support for it seems to come from OpenVZ team - as http://criu.org. But hopefully we can get rid of OpenVZ patched kernels - so it will be only the choice of userspace tools (for containers). Our goal would be to have something way simpler than Openstack (which is huge and quite a mess in its current state - if you really want to create a production grade system with it) - and to have a nicely packaged + easy to use system (which might not support all 1001 ways of doing the same thing - yet enforcing some simple best-practices). So - if anybody interested - lets discuss!
