oVirt 4.1.4 Release Notes

The oVirt Project is pleased to announce the availability of 4.1.4 Release as of July 28, 2017.

oVirt is a free open-source distributed virtualization solution, designed to manage your entire enterprise infrastructure. oVirt uses the trusted KVM hypervisor and is built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible.

This release is available now for Red Hat Enterprise Linux 7.3, CentOS Linux 7.3 (or similar). Packages for Fedora 24 are also available as a Tech Preview.

If you’d like to try oVirt as quickly as possible, follow the instructions on the Download page.

For complete installation, administration, and usage instructions, see the oVirt Documentation.

For a general overview of oVirt, read the About oVirt page.

To learn about features introduced before 4.1.4, see the release notes for previous versions.

EPEL

Don’t enable all of EPEL on oVirt machines.

The ovirt-release package enables the EPEL repositories and includes several specific packages that are required from there. It also enables and uses the CentOS SIG repos, for other packages.

EPEL currently includes collectd 5.7.1, and the collectd package there includes the write_http plugin.

OpsTools currently includes collectd 5.7.0, and the write_http plugin is packaged separately.

ovirt-release does not use collectd from EPEL, so if you only use it, you should be ok.

If you want to use other packages from EPEL, you should make sure to not include collectd. Either use includepkgs and add those you need, or use exclude=collectd*.

oVirt 4.1.4 Release Notes

What’s New in 4.1.4?

Enhancements

oVirt Release Package

BZ 1461813 [RFE] Provide hook for vGPU
RHV-H now supports vGPU for nVidia GPUs, by including vdsm-hook-vfio-mdev.

oVirt Engine

BZ 1438408 [RFE] Cluster maintenance scheduling policy
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.
BZ 1465862 [downstream clone - 4.1.4] [RFE] Need UI element to view affinity labels in the VM and host dialog boxes
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.
BZ 1450293 After upgrade still can’t connect to engine web ui with chrome 58 (due to missing subjectAltName)
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.
BZ 1319323 [RFE] Do not check VLAN ID for duplicates (allow them on different networks, DCs… ?)

VDSM

BZ 1461813 [RFE] Provide hook for vGPU
RHV-H now supports vGPU for nVidia GPUs, by including vdsm-hook-vfio-mdev.
BZ 917062 [RFE] add abrt integration
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.
BZ 1461295 [downstream clone - 4.1.4] [RFE] Provide a way to correlate each ‘run and protect’ thread to its task

oVirt Engine Extension AAA JDBC

BZ 1452668 [downstream clone - 4.1.4] [RFE] possibility to enter encrypted passwords in –password option
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.

No Doc Update

oVirt Engine

BZ 1470802 scheduling policy required properties have no defaults

Release Note

oVirt Engine

BZ 1469478 hide InClusterUpgrade policy
The InClusterUpgrade scheduling policy was only useful for upgrading cluster nodes from RHEL6 to RHEL7. RHEL6 is not an supported OS for oVirt hosts anymore so the policy is not doing anything nowadays. We might re-enable it if an use case shows up in the future.
