oVirt 4.4.0 Beta release refresh is now available for testing
The oVirt Project is excited to announce the availability of the beta
release of oVirt 4.4.0 refresh for testing, as of April 3rd, 2020
This release unleashes an altogether more powerful and flexible open source
virtualization solution that encompasses hundreds of individual changes and
a wide range of enhancements across the engine, storage, network, user
interface, and analytics on top of oVirt 4.3.
Important notes before you try it
Please note this is a Beta release.
The oVirt Project makes no guarantees as to its suitability or usefulness.
This pre-release must not be used in production.
In particular, please note that upgrades from 4.3 and future upgrades from
this beta to the final 4.4 release from this version are not supported.
Some of the features included in oVirt 4.4.0 Beta require content that will
be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 beta yet
due to some incompatibility in openvswitch package shipped in CentOS Virt
SIG which requires to rebuild openvswitch on top of CentOS 8.2.
Known Issues
-
ovirt-imageio development is still in progress. In this beta you can’t
upload images to data domains using the engine web application. You can
still copy iso images into the deprecated ISO domain for installing VMs or
upload and download to/from data domains is fully functional via the REST
API and SDK.
For uploading and downloading via the SDK, please see:
-
https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload_disk.py
-
https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/download_disk.py
Both scripts are standalone command line tools, try --help for more info.
