We have another option now to install ovirt_imagieo, via pip. It may work on any Linux distro with qemu-img (>= 4.2) and python >= 3.6, but I tested it only on Fedora 34 (qem-img 6.1, python 3.9). Note that the imageio client depends qemu-img and qemu-nbd, provided by qem-img package on rpm based distros. pip cannot install this package, so you need to install it yourself using your distro package manager. Here an example using virtual environment: $ python3 -m venv venv $ source venv/bin/activate $ pip install --upgrade pip $ pip install --upgrade ovirt-imageio $ pip install --upgrade ovirt-engine-sdk-python The imageio client is not very useful as is unless you want to write an application using the python library. But we have several useful example scripts in the ovirt engine python SDK. They are not installed by pip, but you can get them via git: $ git clone https://github.com/oVirt/python-ovirt-engine-sdk4.git Finally, you need to add configuration file pointing to your engine(s): $ cat /home/nsoffer/.config/ovirt.conf [myengine] engine_url = https://myengine.example.com username = admin@internal password = password cafile = /home/username/certs/myengine.pem Now you can upload a disk image using: $ python-ovirt-engine-sdk4/examples/upload_disk.py -c myengine --sd-name my-storage-domain --disk-sparse disk.qcow2 These scripts will be most useful and should work with 4.3: - upload_disk.py - download_disk.py These require ovirt 4.4: - list_disk_snapshots.py - download_disk_snapshot.py - backup_vm.py Nir _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/MATMO35FHP7QMUAGHQUVGRRGBWJLLQ5J/
