oVirt 4.3.6 Release Notes

What’s New in 4.3.6?

oVirt Engine WildFly

  • BZ 1732499 Require WildFly 17.0.1 for oVirt Engine 4.3
    oVirt engine 4.3.6 now depends on WildFly 17.0.1.FINAL

oVirt Engine

  • BZ 1732499 Require WildFly 17.0.1 for oVirt Engine 4.3
    oVirt engine 4.3.6 now depends on WildFly 17.0.1.FINAL


oVirt Engine

  • BZ 1741152 [downstream clone – 4.3.6] [RFE] – Creating an NFS storage domain the engine should let the user specify exact NFS version v4.0 and not just v4
  • BZ 1680498 [RFE] Implement priorities for soft affinity groups
    Added priorities to nonenforcing affinity groups. If not all affinity groups can be satisfied, the groups with lower priority are broken first.

    Some affinities can be more important than others. Previously, it was not possible to specify it.

    When a VM is started or migrated, a host is chosen, such that the broken affinity groups have the lowest priority.

    A new text field has been added to the affinity group dialog, to set to priority. It can contain any real number, not just integers. Priority can also be set using a new parameter in the REST API.


  • BZ 1744027 [downstream clone – 4.3.6] [RFE] Warn if SELinux is disabled when upgrading RHV-H


  • BZ 1753901 ioprocess – Implement block size detection compatible with Gluster storage
    Provide API to probe block size of underlying filesystem.

    The API is needed by vdsm to support 4k storage on gluster.

    Vdsm uses this now to support 4k gluster storage.

    Ich bin derzeit dabei, ein wenig mit Ovirt zu experimentieren.
    Was mir fehlt, ist eine anschauliche Darstellung der einzelnen Komponenten von Ovirt. Eigentlich möchte ich nur VMware damit ersetzen. Dafür muss ich aber einen Node aufsetzen, eine Maschine mit Engine, benötige einen shared Storage…

    Alles dich riesig aufwendig. Vielleicht auch nicht, wenn man die Zusammenhänge verstehen könnte.
    Was mach der Node, was die Engine. Wie sichere ich meine Konfiguration?

    Ein paar Grafiken wären hilfreich.
