oVirt 4.0.5 Release Notes

Enhancements

oVirt Engine

Team: Integration
  • BZ 1340810 4.0 engine-backup should hide reports backup/restore
    Feature:

    engine-backup –mode=restore does not restore reports db/conf even if found in backup.

    Reason:

    In 4.0 Reports is not packaged/supported anymore. engine-backup of 4.0 supports restoring a 3.6 backup, which might include Reports data.

    Result:

    If Reports db dump is found in a backup, engine-backup notifies the user that it will not be restored, and does not restore Reports db/conf.

Team: Virt
  • BZ 1346847 virt-v2v basic REST API
    With this update, the ability to import virtual machines from VMware, VMware OVA, XEN, and KVM via the Red Hat Virtualization REST API has been added. Previously, this was only possible using the web UI.

VDSM

Team: SLA
  • BZ 1373832 Add all APIs needed to support jsonrpc in MOM
    The Memory Overcommit Manager (MoM) can now use JSONRPC insead of XMLRPC for communication with the VDSM.

oVirt Hosted Engine Setup

Team: Integration
  • BZ 1347340 [RFE] hosted engine should check the actual size of the qcow instead of relying on the OVA
    Previously, ovirt-hosted-engine-setup relied on the OVA metadata to determine the size of the image contained in OVAs, and the amount of temporary disk space needed to unpack it. However, sparsified images would report a value much higher than the actual space required on-disk. Now, ovirt-hosted-engine-setup will check the actual size of images contained in OVAs in order to determine the amount of temporary storage required.
  • BZ 1343451 upgrade-appliance should warn about sshd keys changes
    During the migration of the hosted-engine VM from 3.6/el6 to 4.0/el7, hosted-engine-setup is going to deploy a new appliance and so the ssh keys are going to be regenerated.
    So the user has to remove previous entries from know_hosts on his clients.

oVirt Host Deploy

Team: Network
  • BZ 1373968 Deploying a host with an external Neutron network configured fails
    Previously, with the release of OpenStack Liberty the Open vSwitch agent ini file location changed. This caused host deployment to fail when the latest releases of OpenStack were used. Now, support for Liberty and newer releases of OpenStack has been added and host deployment no longer fails.

MOM

Team: SLA
  • BZ 1366556 MOM causes Vdsm to slow down, high number of ‚vmGetIoTunePolicy‘ API calls
    This update ensures that the Memory Overcommit Manager (MoM) uses just one request to retrieve the ioTune configuration and status. This retrieval is more efficient and lowers the load imposed on the VDSM.

    Previously one request per virtual machine was made which caused a high load on the VDSM.

oVirt Engine Extension AAA LDAP

Team: Infra
  • BZ 1388083 Use mod_auth_gssapi and mod_session instead of mod_auth_kerb for Kerberos SSO
    Red Hat Enterprise Linux 6 used mod_auth_kerb to setup Kerberos SSO, but this module has been deprecated; mod_auth_gssapi is used instead. This update ensures mod_auth_gssapi and mod_session is used, and that example configurations have been updated.

    For existing customers, mod_auth_kerb will continue to work with previous versions of Red Hat Enterprise Virtualization.

Rebase: Bug Fixes and Enhancements
