ABRT is now integrated with Red Hat Virtualization when initializing hypervisors. ABRT is configured by VDSM and saves meaningful debug information, instead of enormous core-dump reports.
The ClusterInMaintenance scheduling policy was added to limit activity in a cluster during maintenance tasks. When set, no new VMs may be started, except highly available VMs. Highly available VMs are still restarted properly upon host failure and any VM can be migrated. Users can create new highly available VMs and start them manually.
Newer browsers require the subjectAltName extension in certificates for HTTPS. Previously (version 4.1.2 and later), engine-setup created certificates with subjectAltName for new setups, but did not update existing certificates during upgrade.
Now engine-setup can add subjectAltName to existing internal certificates, so that newer browsers will accept them.
Previously, administrators had to enter an unencrypted password when invoking 'ovirt-aaa-jdbc-tool user password-reset'. The password was then encrypted inside ovirt-aaa-jdbc-tool and stored in the database.
This update enables administrators to use the new --encrypted option to enter an already encrypted password when invoking 'ovirt-aaa-jdbc-tool user password-reset'.
However there are some caveats when providing encrypted passwords:
1. Entering an encrypted password means that password validity tests cannot be performed, so they are skipped and the password is accepted even if it does not comply with the password validation policy.
2. A password has to be encrypted using the same configured algorithm. To encrypt passwords, administrators can use the '/usr/share/ovirt-engine/bin/ovirt-engine-crypto-tool.sh' tool, which provides the 'pbe-encode' command to encrypt passwords using the default PBKDF2WithHmacSHA1 algorithm.
RHV-H now supports vGPU for nVidia GPUs, by including vdsm-hook-vfio-mdev.
Previously, users could use the REST API to add/edit affinity labels for virtual machines and hosts, but they could not view this information in the Administration Portal.
In this release, affinity label information is now available in the Administration Portal. It can be seen in the Add/Edit windows for virtual machines and hosts. The window displays all available affinity labels in the system, and for entities with assigned labels, those labels are selected.
Previously, when creating a new VLAN-tagged network, the Manager did not allow the same VLAN ID to be duplicated across various entities, such as networks and data centers.
In this release, it is now possible to use the same VLAN ID across multiple entities, as long as they are not used on the same interface on the hardware node.
