Getting qcow images into oVirt
Hi there, We would like to consume pre-created QCOW images in oVirt/RHEV. So far it seems that the only way to do that would be to store the images in a Glance server which will require us to maintain such server. Trying to put the image in an ISO domain made in show up as a useless "unkonwn" file type in engine. Is there any other way to get the images into oVirt? -- Barak Korren bkorren@redhat.com RHEV-CI Team
Hi There's an upcoming feature to upload a pre-created image into your ovirt system. it is not merged yet, but here's a link if you are interested in more details: http://www.ovirt.org/Features/Image_Upload Anyway, currently you can still manually put an ISO file in an ISO domain, and it should appear in your web admin.

Yeah I know about this, I was hoping there is something I cane use _today_
Anyway, currently you can still manually put an ISO file in an ISO domain, and it should appear in your web admin.
ISO Files are not interesting (who wants to run an installer? Most OS projects give you ready-made QCOW2 images now days). What can I do with a QCOW2 file? -- Barak Korren bkorren@redhat.com RHEV-CI Team

Maybe this will help you?: https://jonarcher.info/2014/02/import-regular-kvm-image-ovirt-rhev/ Regards, Joop

Thanks! this looks like a step in the right direction! A few caveats I see and further questions: 1. Seems I would require a storage domain where I can access the files from somewhere external to the system. I guess I could try using a VM running on the same engine instead and attach/detach disks to/from it. 2. This creates a non-sparse, non-thin VM disk no? How much space did the disk take once you were done? -- Barak Korren bkorren@redhat.com RHEV-CI Team
Hi, You can import regular qcow2 images into ovirt with few steps: 1)check what kind of image you have qemu-img -info vm4import.img 2) create an vm with exact disk image size as qemu-img -info shows. 3) run vm in paused mode(sometimes it is hard to find out the VM disk) 4) go to host where paused vm is running: find /rhev |grep "your vm uuid" and get your vm image UUID 5) do not use dd, use better qemu-img convert -p -O raw $1 ${2} or qemu-img convert -p -O qcow2 $1 ${2} with -p option you have a nice progress bar:) Then poweroff the paused vm and start it. Maybe someone has a better tools, but sometimes better to get an idea behind the scene without any wodoo scripts. *********************************************************** Dr. Arman Khalatyan eScience -SuperComputing Leibniz-Institut für Astrophysik Potsdam (AIP) An der Sternwarte 16, 14482 Potsdam, Germany *********************************************************** On Mon, Feb 8, 2016 at 10:40 AM, Barak Korren <bkorren@redhat.com> wrote:
