oVirt 4.3.4 Release Notes
The oVirt Project is pleased to announce the availability of the 4.3.4 release as of June 11, 2019.
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 7.6, CentOS Linux 7.6 (or similar).
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 4.3.4, 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.
If you want to use other packages from EPEL, you should make sure to
use includepkgs and add only those you need avoiding to override
packages from other repos.
What’s New in 4.3.4?
Release has been updated on June 19th providing ovirt-ansible-vm-infra-1.1.18, ovirt-ansible-image-template-1.1.11 and ovirt-engine-metrics-1.3.2 fixing metrics deployment with Ansible 2.8.
Enhancements
VDSM JSON-RPC Java
- BZ 1689702 GC overhead limit exceeded due to org.ovirt.vdsm.jsonrpc.client.events.SubscriptionHolder
A new configuration variable ‘EventPurgeTimeoutInHours’ has been added to set the number of hours an event can stay in the queue before being cleaned up. The variable can be modified using engine-config. The initial default value is 3 hours.
oVirt Provider OVN
- BZ 1685983 [RFE] Support IPv6 for address type in subnets in rhel8 guests
This feature adapts the existing IPv6 address support for OpenStack Networking API subnets, making its address mode configurable, as per the networking API subnet ‘address_mode’ parameter.
The addresses can now be generated from RA messages, when the address mode parameter is set to ‘dhcpv6_stateless’. This configuration also allows for the MTU of the logical network to be configured, which would be otherwise impossible for ipv6 logical networks.
oVirt Cockpit Plugin
- BZ 1704183 [RFE] Allow to choose alternative to ICMP ping for hosted engine network test
Feature: Allow users to do a network test in other ways rather than ICMP (ping).
Users can choose to do a network test with:
1. DNS
2. ICMP
3. TCP
4. None of the above (do no test)
oVirt Engine
- BZ 1712253 Add MDS CPU types
added MDS versions of the CPUs added MDS variants to 4.1,4.2,4.3 CPU types to mitigate https://access.redhat.com/security/vulnerabilities/mds - BZ 1403677 [IPv6] - allow and enable gluster network with only ipv6 boot protocol
Feature: Allow and enable a Gluster network with IPv6 boot protocol only
Reason: Enable users to work with a Gluster network on a pure IPv6 network
Result: Users can connect to a Gluster storage over IPv6 without need for IPv4. - BZ 1689702 GC overhead limit exceeded due to org.ovirt.vdsm.jsonrpc.client.events.SubscriptionHolder
A new configuration variable ‘EventPurgeTimeoutInHours’ has been added to set the number of hours an event can stay in the queue before being cleaned up. The variable can be modified using engine-config. The initial default value is 3 hours. - BZ 1341161 [RFE] Add “Other Linux (kernel 4.x)” to OS types
A new generic Linux x86 operating system selection named ‘Other Linux (kernel 4.x)’ has been added to the drop down list of operating systems available when creating a new virtual machine in Red Hat Virtualization. - BZ 1655503 [RFE]Add “windows 2019 x64” support
This release adds support for virtual machines to use Windows 2019 x64 in the Administration Portal.
VDSM
- BZ 1695567 [downstream clone - 4.3.4] [RFE] Support VMs with VNC console on a FIPS enabled hypervisor
When a host is running in FIPS mode, VNC must use SASL authorization instead of regular passwords because of the weak algorithm inherent in the VNC protocol.
In order to facilitate that process, the Ansible role ‘ovirt-host-setup-vnc-sasl’ is provided. It must be run manually on all FIPS hosts. The role does the following:
* Creates an (empty) SASL password database
* Prepares an SASL configuration file for qemu
* Changes the libvirt configuration file for qemu
OTOPI
- BZ 1694423 [RFE] disable dnf by default on EL7
OTOPI’s DNF packager is now disabled on EL7 by default, even if dnf is installed. To enforce otopi to try it, add to the relevant tool’s (e.g. engine-setup) answer file:
PACKAGER/dnfpackagerEnabled=bool:True
oVirt Windows Guest Tools
- BZ 1713705 Rebase WGT on qxl-wddm-dod-0.19 / virtio-win 171
oVirt Guest Tools ISO has been updated including new virtio-win-prewhql drivers collection version 171, providing updated qxl-wddm-dod driver version 0.19 (see https://gitlab.freedesktop.org/spice/win32/qxl-wddm-dod/blob/master/Changelog for more information).
