install python package ovirt_imageio for Ovirt 4.3
I want to use python script running from a host to automate the remote kvm manager's vm backup. Our ovirt version is 4.3. I have installed ovirt-imageio-daemon on the host I tried to yum install ovirt-imageio-client (we use yum), it couldn't find the package. error message: Loaded plugins: ulninfo, vdsmupgrade, versionlock ovirt-4.3 | 3.0 kB 00:00:00 ovirt-4.3-extra | 3.0 kB 00:00:00 ovirt-master-snapshot | 3.0 kB 00:00:00 ovirt-master-snapshot-static | 3.0 kB 00:00:00 No package ovirt-imageio-client available. I tried to copy folder ovirt_imageio from ovirt-imageio to my python library directory, it could not compile the c file "ioutil.c" Can anybody help me install the python package? Am I installing on the correct place, do I need to use the python script only on the host that installed the kvm manager?
Hi Grace, ovirt 4.3 reached EOL more than a year ago, upgrading to ovirt 4.4 is strongly recommended. Mark On Wed, Oct 20, 2021 at 2:24 PM Grace Chen <hippoqian@gmail.com> wrote:

It’s company software, not sure if they can upgrade or not, is it free to uograde? On Wed, Oct 20, 2021 at 7:33 AM Mark Kemel <mkemel@redhat.com> wrote:

Should you run the script on any vm or have to be the host with kvm manager installed? On Wed, Oct 20, 2021 at 7:57 AM Mark Kemel <mkemel@redhat.com> wrote:

(Copied from private mail in case it is useful for others) ovirt-imageio-client was released in 4.4, and is not compatible with python 2. In general the client supports older version of ovirt server (e.g. 4.3), but it is not tested in this configuration. You can try to create a vm with centos 8 and ovirt-release44.rpm and install the client in this vm. Then you can run the backups on the vm, and store the backups in NFS server accessed by this "backup" vm. Note that you will get much better performance with ovirt 4.4., when running the client directly on the ovirt host. 4.4. also supports incremental backup, which is much faster and simpler compared with snapshot based backup that you probably plan to use.\ Nir

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
