What’s New in 4.4.1?

Release Note

oVirt Engine WildFly

  • BZ 1830951 Rebase on Wildfly 19.1

    oVirt Engine is now running on WildFly 19.1.0.FINAL


oVirt Engine

  • BZ 1763812 [RFE] Move the Remove VM button to the drop down menu when viewing details such as snapshots

    Feature: Moved the VM remove button to the more button’s drop down menu.

Reason: For usability. Many users would press the remove VM in a details tab view thinking that it would just remove the detailed item. Instead it deleted the VM itself.

Result: The user now has to press the more drop down button to delete the VM, but it should be less confusing as to which button to use when attempting to remove a detail such as a snapshot.

  • BZ 1841083 bump up max memory limit to 6TB

    In 4.4 the maximum memory size for 64bit x86_64 and ppc64/ppc64le VMs is now 6TB. For x86_64 this limit is applied also to VMs in 4.2 and 4.3 Cluster Levels.
