oVirt 4.0.6 Release Notes

The oVirt Project is pleased to announce the availability of 4.0.6 Release as of January 10, 2017.

oVirt is an open source alternative to VMware™ vSphere™, and provides an awesome KVM management interface for multi-node virtualization. This release is available now for Red Hat Enterprise Linux 7.2, CentOS Linux 7.2 (or similar).

To find out more about features which were added in previous oVirt releases, check out the previous versions release notes.

An updated documentation has been provided by our downstream Red Hat Virtualization

oVirt 4.0.6 Release Notes
1. Install / Upgrade from previous versions
2. Bug fixes

Install / Upgrade from previous versions

Users upgrading from 3.6 should be aware of following 4.0 changes around authentication and certificates handling:

Single Sign-On using OAUTH2 protocol has been implemented in engine to allow SSO between webadmin, userportal and RESTAPI. More information can be found at https://bugzilla.redhat.com/show_bug.cgi?id=1092744
Due to SSO it’s required to access engine only using the same FQDN which was specified during engine-setup invocation. If your engine FQDN is not accessible from all engine clients, you will not be able to login. Please use ovirt-engine-rename tool to fix your FQDN, more information can be found at /documentation/how-to/networking/changing-engine-hostname/ . If you try to access engine using IP or DNS alias, an error will be thrown. Please consult following bugs targeted to oVirt 4.0.4 which should fix this limitation: https://bugzilla.redhat.com/show_bug.cgi?id=1325746 https://bugzilla.redhat.com/show_bug.cgi?id=1362196
If you have used Kerberos SSO to access engine, please consult https://bugzilla.redhat.com/show_bug.cgi?id=1342192 how to update your Apache configuration after upgrade to 4.0
If you are using HTTPS certificate signed by custom certificate authority, please take a look at https://bugzilla.redhat.com/show_bug.cgi?id=1336838 for steps which need to be done after migration to 4.0. Also please consult https://bugzilla.redhat.com/show_bug.cgi?id=1313379 how to setup this custom CA for use with virt-viewer clients.

Fedora / CentOS / RHEL

In order to install it on a clean system, you need to install

# yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm

and then follow documentation from our downstream Red Hat Virtualization

If you’re upgrading from a previous release on Enterprise Linux 7 you just need to execute:

  # yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm
  # yum update "ovirt-*-setup*"
  # engine-setup

Upgrade on Fedora 22 and Enterprise Linux 6 is not supported and you should follow our Migration Guide in order to migrate to Enterprise Linux 7 or Fedora 23.

Enhancement

VDSM

Team: SLA

BZ 1374988 MOM causes Vdsm to slow down, high number of ‘vmGetIoTunePolicy’ API calls - vdsm
Feature:

Use just one request (instead one per VM) to retrieve the ioTune configuration and status.

Reason:

The amount of requests needed was causing high load on VDSM.

Result:

MOM can now use much more efficient data retrieval method that would lower the load imposed on VDSM.
