Import KVM/libvirt VMs to oVirt
Hi list, finally I managed to install oVirt on my new server and so far it is really great. The next step on my side it to migrate VMs from another server (KVM/libvirtd/virt-manager) to oVirt. I was trying to find something in the documentation but so far no luck. Google was pointing me to tow options: - virt-v2v - import-to-ovirt.pl (script from Richard WM Jones) Currently I'm trying to migrate a Win7 VM (with VirtIO) with import_to_ovirt bzt I receive the following error message: ./import-to-ovirt.pl: no operating system was found on the disk I'm executing the following command: ./import-to-ovirt.pl /path-to-image-file/disk.img hostname:/export-domain Is anyone able to support me here? As both systems are running KVM there should be a quite easy way to migrate the VMs or not? Best regards Christoph

Adding Richard. IIRC people managed to do that by merely creating a new vm and copying the existing one over the new empty disk. No idea about details, you might want to search the list archives. Best, -- Didi
Hi, thank you for the quick response. Yes I can confirm that I'm also able to perform this through copying of the image but then you need to know the exact file name of the disk you need to overwrite. Is there a way to see the file name also in the oVirt admin portal? Best regards Christoph Am 20.12.2015 um 11:24 schrieb Yedidyah Bar David:

If you check the "Disks" tab, you'll see there an ID tab. For nfs/qcow, that's a directory name to be found under 'images' inside the storage domain. Under this directory you'll find several files (data, metadata and lease) per each snapshot of this disk. Not sure any of this is documented and/or intended for direct manipulation. Best,
Best regards Christoph

The error means libguestfs doesn't think there is anything on your source disk (disk.img), eg it is blank or there is no detectable operating system on it. Do: export LIBGUESTFS_DEBUG=1 export LIBGUESTFS_TRACE=1 ./import-to-ovirt.pl [....] and capture the full output. From that output it is possible to work out why inspection of the source disk failed.

Looks like you need to install either libguestfs-winsupport (assuming the host is RHEL/CentOS), because this is required to process any Windows disk images. libguestfs-winsupport can be found here for RHEL < 7.2: https://people.redhat.com/~rjones/libguestfs-winsupport/ and is included in the base OS in RHEL >= 7.2.

Right, sorry, that's a bug in import-to-ovirt. I've just pushed a fix to the git repo. Thanks for your patience!
