I've asked, a few times, for the CentOS Linux images in AMP to be enabled for all instance types where the image will work.

That way you can actually do whatever contexutalisation you need. Here is an example you can likely clone and extend: https://github.com/kbsingh/atomic-ci/blob/master/tests/z_0-genConfigDrive/1-genConfigDrive.sh You would then just need to boot the instance with this config drive .iso attached as the cdrom to the machine, which should also just be scriptable.

Re: [CentOS-virt] CentOS 7 AMI Building
I highly recommend actually looking at the images :) its just a minimal install with cloud-init from extras/ added in ( for 7, the 6 ones dont have cloud-init ). the installed content delivered from the minimal.iso and the ami's should be identical in pretty much every respect. If you really want a kickstart for it, I can build one, but just run a minimal.iso install, add cloud-init to the %packages and bob's your uncle.

following Cloud SIG example[1] I would like to start defining the CBS tags

For opening the discussion I suggest:
- virt${release}-common : packages not related to xen or kvm, used by at
least 2 projects
- virt${release}-xen: xen hypervisor related packages
- virt${release}-kvm: kvm hypervisor related packages (like qemu-kvm-ev)
- virt${release}-ovirt : ovirt packages and dependencies, not required by

- virt${release}-docker : docker packages and dependencies, not required by

Looks reasonable at first blush.

The Virt SIG wants to provide a stable base; the (1) group of people mentioned in the Fedora virt-preview wiki page. As it happens, we plan on updating our libvirt package fairly frequently at first; but that's just to get some important Xen functionality in as soon as possible. Once the Xen functionality for libvirt has stabilized, we'll probably stop. Our plan for qemu was to re-build the exact RHEL package, but with snapshotting enabled. What you're describing would essentially be a completely separate project: designed for people (like yourselves) who want bleeding-edge versions. could we do this as a part of a -testing or -next repo, but still be a part of the VirtSIG ? I think it would be great to see some of the upstream devel stuff being built and tested, specially if it can be automated. Needing to do this manually, and curate it locally would be quite hard. We would also need to make sure that stuff from that repo never hits a release repo on centos.org, but we can likely enforce that. -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

May not be flexible enough We ship a test/devel grade CentOS-6-x86_64-pv image ( well, its a qcow2 image, should work for pvhvm as well, the fstab is label driven ).[1] The biggest problem in doing pre-baked images is the instance metadata. We need to find an easy way to get network settings into the instance and the root password ( or key ), and finally - in some cases, console redirection/setup, but i dont think the console is a deal breaker or a big deal. The network and access credentials however are. In a typical cloud environ this info would come from the cloud controller's metadata service; on a typical virtualised setup though this becomes an issue ( and isnt really Xen specific ). We could work around this by making some assumptions, we could 'own' dnsmasq and ensure that either libvirt is running and doing dhcp, otherwise we do the dhcp with some sane defaults, or we setup a script to 'instantiate image', which asks how the user wants to setup the instance ( pvhvm, hvm, pv ), the root password or key to use, and the network settings ( and if this is run on the dom0, we could even ask what bridge or device to connect with as well as the settings ).[2] Ofcourse, having these images pushed from here mean that clouds or virtualised environs that have metadata services are able to just-use the image as is, not needing any more tooling etc. And we can easily push monthly image updates and when things like heartbleed come around, there is a single place we need to update. - KB [1]: http://cloud.centos.org/centos/6/devel/ [2] might need to pull in all of libguestfs to make the changes, which in turn has its own challenges if run inside a virtualised environ. -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt
[CentOS-virt] Xen DomU supoprt in RHEL 7 and the CentOS Plan
Hi Guys, so far, in rhel7rc its pretty clear that Xen instances ( domUs ) are not going to boot with the RHEL7rc kernel. Also, i think at this point its a safe bet that these things wont change to GA - no way to accertain that, but its a safe bet ). Wondering if someone has looked into what the challenges might be to enable this support, and then what the options are to deliver this support ? If we can get the stuff staged up, we can work it during the Distro QA stages and target ( potentially ) a in-sync release for Xen support when CentOS7 goes GA - KB -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

I am kind of hoping we can use this wider than the testing env only, it would allow us to ship generic images to be used outside a cloud like environ that handles such metadata/acl setup. Another part of the libguestfs problem is that the way its built into CentOS-6, it has a hard dep on qemu-kvm, which in turn conflicts with qemu-xen; Again this might be an artificial conflict and perhaps needs investigating, but for now, there is no way to install libguestfs on a machine running xen4centos. In this specific test case, we can install libguestfs, make the changes we need, then install xen4centos before the reboot, but the qemu-ndb hack seemed far less intrusive. btw, speaking to the upstream ( rich jones ) about this, there are moves to unbundle chunks of stuff away, most of the hard deps for libguestfs come from features that are otherwise well isolated; but those changes are still being executed upstream, no idea when its going to make it into CentOS and other distro's. - KB -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt
[CentOS-virt] injecting a key into the xen images
hi, As a part of the test suite for xen that I've started off - I needed a way to inject a ssh key into the image [1]; so have come up with this : https://github.com/CentOS/sig-virt-t_xen/blob/master/scripts/inject_ssh.sh ; its not pretty and it wont handle lots of use cases, but it does what is needed at hand. Comments ? I'm also considering if we should include this script within the .bz2 file for the image itself ( and for all such images ) Further feature creep, should we now extend this script a bit to also include a 'download and inject ssh key' with some param's like : ./get_image.sh 6.5 x86_64 path to sshkey and that can hit http://cloud.centos.org/calculated path to image/ ; download it, and add the key. This script could live within centos-release-xen dramatically reducing the barrier to entry and get-go with the xen4centos stack. thoughts ? - KB 1: qcow2, http://cloud.centos.org/centos/6/devel/CentOS-6-x86_64-xen-pv.bz2 -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

[CentOS-virt] Fwd: Building Xen on RHEL7
Original Message Subject: Building Xen on RHEL7 Date: Thu, 19 Dec 2013 18:57:22 + From: Wei Liu wei.l...@citrix.com To: centos-virt@centos.org Hi all This is a record of how I build Xen on RHEL 7. Hope this is helpful for people who want to package Xen for the upcoming CentOS 7. Basically it's not too much hassle to build Xen on RHEL 7. I'm in no way a packaging expert on RPM-based systems so I just list what's needed. The Yum repo I'm using is the public beta mirror at https://mirrors.fedoraproject.org/publiclist/RHEL/7/x86_64/. I cloned Xen tree from git://xenbits.xen.org/xen.git and used master branch. Dependences and requirements are listed by components. # To make top level ./configure pass: yum install -y gcc python-devel acpica-tools libuuid-devel ncurses-devel glib2-devel libaio-devel yajl-devel zlib-devel I also need to install dev86. I downloaded the latest version from http://www.debath.co.uk/dev86/ and installed it by hand. I noticed there's a dev86 package in Xen4Centos repo. We should be able to reuse that. And we also need to do ln -s /lib64/libcrypto.so.1.0.1e /lib64/libcrypto.so otherwise configure complains it cannot find libcrypto while that library is actually there. There's no markdown library in existing yum repo so some documents won't be built but that's not critical. And optionally if you want to use oxenstored: yum install -y ocaml # To build tools: ## To build hvmloader: yum install -y glibc-devel.i686 ## To build qemu-xen-traditional yum install -y SDL-devel ## To build qemu-xen-upstream yum install -y pixman-devel # To build stubdom yum install -y texinfo By now you should be able to just run ./configure; make dist in top level Xen source code directory without getting any error (hopefully). There's warnings though because gcc 4.8 has stricter check than previous versions. I didn't build blktap, as RHEL 7 uses 3.10 kernel and Xen now has upstream QEMU, which should be able to cover all use cases. However default kernel only has frontend supports enabled (built as module), so we might need to alter its config or supply alternative Dom0 kernel. Have fun and Merry Christmas.

Hi, On 08/01/2013 03:22 AM, CS wrote: Just one comment about the raindrops project; having it as a closed source project that's separate from the official CentOS project, and has no recognizable organization behind, makes it hard to use in any sizable company. Inevitably there would be questions about security and verification of what is in the build, risk of being dependent on a project that may or may not be around in a few years. If it were open source, or perhaps under the CentOS brand, that would make it easier to use. Just an fyi... Couple of things : projectraindrops.net runs completely disconnected from CentOS Project - there is no resource overlap other than the fact that I wrote some of the scripts behind it - and I do the same for centos.org as well. That is by design. Couple of wins in there is that we can build Fedora and Debian images as well at Raindrops, which we cant in the private instance that runs inside the CentOS buildservices[1]. Also, the code behind it is basically just libvirt running kickstarts that users submit in native hypervisors. so the only bit that isnt already visible is the web interface ( which is sinatra running a few tasks to prep data for virt-install ). Finally, one of the things that I want to get to is being able to download a project raindrops VM that is already setup for a target environ: eg. click a button to have your own instance come up in AWS/EC2 or download something that can run as a in-cloud-off-premise openstack vm or opennebula vm. I guess this is really what your request was about : and its something that is in the pipelines, blocker is mostly hours in a day, but I hope to have this done by the end of this year. Flipping over to the other side : AWS is a vendor environment, we try quite hard to not be a vendor specific effort and try to keep things as generic as possible. AWS for years refused to accept that CentOS was an entity or that CentOS images were in demand ( the first set of conversations I had with them was back in 2008... and it took till 2013 to get that issue resolved ). In this case the resolution was them acknowledging that we exist, that the content we churn out is acceptable as is; essentially reducing ( but not removing ) the hostility that AWS has towards open source projects at large. And we on the other hand need to be careful about how we interface with them, and what that interface brings in and takes away from our side. After all, it might be a specific vendor environment - its still quite a large one. Hope this helps clear up a bit more of the air, - KB [1]: Since centos buildsys has no inbound content, we could / would not be able to expose that interface in a manner that would allow other distro's content to be consumed in a sane manner. -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

hi, We are going to run a public test cycle for the CentOS AMI's that we publish as the official ones. This test will run for 1 week, ending on the 4th May, when we will do the formal release. Request: please dont use these AMI's for production, please dont use these AMI past the 4th of May. For all change and fix requests, either post to this list and we will attempt to get things turned around super quick, or find either Tru or me in #centos-devel or #centos-virt on irc.freenode.net.

Hi Richard, On 12/19/2012 05:37 PM, Richard Clark wrote: I've noticed that instance-backed AMIs no longer seem to exist for the 'official' CentOS images, though the EBS ones are fine.. Looking at the wiki (http://wiki.centos.org/Cloud/AWS), the AMIs listed on marketplace are slightly newer than what's listed on the wiki, so just wondering if something got overlooked after the last build? This whole thing is an artifact of the way in which the AWS guys setup the images. We dont have access to publish to the MarketPlace, we need to get an instance backed image going, generate an EBS backed one from there and then send that over to the AWS-MP people, who then do some testing, do their own magic foo, and publish to all regions and zones. Hence, they are newer than the ones we pushed out to AWS-MP. The AWS images at our end are coming from the raindrops infra that I setup and have been plodding away at for the last few months. More details about that and a proper announcement / release in a few weeks ( planning on getting things all stitched up in time for Fosdem ). What I am hoping to do is have the actual images published to cloud.centos.org in a way that people can download, add their own bits, and register + use as they want to, rather than going via the Market Place click-about. Kind of like we have the OpenNebula images ( and the openstack / eucalyptus ones coming soon ). Keep in mind that the public raindrops interface will have the ability for anyone to throw a kickstart at it, and have it deliver a working image to the AWS ID specified.

[CentOS-virt] Vendor Specific / Agnostic images
hi guys, I've been going round in circles trying to workout the best way to handle vendor agnostic images and in the interest of sanity and actually getting something out of the door - it looks like the best pln is to get the vendor specific requirements and push images with them ( and suitability marked ) With that in mind, AWS is a good target to start with. Do people have opinions on : - root or ec2-user for login ? - cloud-init ( we can use the one from EPEL, it needs a few things sorted, but that should not be too hard ) - selinux as enabled, with a hook in user-data that allows people to set permissive mode at time of instance creation For step1, I was thinking it would be best to just have c5/6 32/64bit minimal images ( using the pygrub AKI ) and make them available on instance-backed as well as EBS backed. Finally, would appreciate having some people help test the images privately before we start pushing publicly - if anyone can help with that, please get in touch with me at kbsingh@ project domain or the domain this email came from.

And yes, publish lots of machine details and also details on the code / platform / versions used. I will try to do the same ( but will limit my testing to whats already available in the distro ) thanks - KB ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt
