# oVirt 3.6.0 BETA Release Notes

The oVirt Project is pleased to announce the availability of oVirt 3.6.0 Third Beta release as of August 20th, 2015.

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 Fedora 22, Red Hat Enterprise Linux 6.7, CentOS Linux 6.7, (or similar) and Red Hat Enterprise Linux 7.1, CentOS Linux 7.1 (or similar).

To find out more about features which were added in previous oVirt releases, check out the [previous versions release notes](http://www.ovirt.org/Category:Releases). For a general overview of oVirt, read [ the Quick Start Guide](Quick_Start_Guide) and the [about oVirt](about oVirt) page.

### Experimental Docker Integration

oVirt Engine setup now provides experimental [ Cinder and Glance](CinderGlance Docker Integration) automated deployment using Docker

### Self Hosted Engine FC Support

Hosted Engine has now added support for [FC storage](Features/Self_Hosted_Engine_FC_Support)

### Self Hosted Engine Gluster Support

*   Hosted Engine has now added support for [Gluster storage](Features/Self_Hosted_Engine_Gluster_Support)

### oVirt Live

oVirt Live has been rebased on CentOS 7 allowing to run oVirt in 3.6 compatibility mode

### Experimental Debian Support for Hosts

Experimental support for running oVirt Hosts on Debian (or similar) has been added providing custom packaging of needed dependencies.

### Fedora 22 Support

Support for running oVirt on Fedora 22 (or similar) has been added providing custom packaging of Wildfly 8.2.0.

### Known Issues

*   On Fedora 22 you'll need to execute

      dnf install yum

reintroducing yum package manager in order to use the host, being dnf not yet supported by otopi.

*   VM and VM pool creation from template doesn't work () but you can create new VMs from scratch.

<!-- -->

*   Use SELinux Permissive mode in order to avoid denials using VDSM and Gluster

<!-- -->

*   NFS startup on EL7 / Fedora20: due to other bugs ( or ), NFS service is not always able to start at first attempt (it doesn't wait the kernel module to be ready); if it happens oVirt engine setup detects it and aborts with

      [ INFO  ] Restarting nfs services
      [ ERROR ] Failed to execute stage 'Closing up': Command '/bin/systemctl' failed to execute

Retrying (engine-cleanup, engine-setup again) it's enough to avoid it cause the kernel module it's always ready on further attempts. Manually starting NFS service (/bin/systemctl restart nfs-server.service) before running engine setup it's enough to avoid it at all.

*   NFS startup on EL7.1 requires manual startup of rpcbind.service before running engine setup in order to avoid

      [ INFO  ] Restarting nfs services
      [ ERROR ] Failed to execute stage 'Closing up': Command '/bin/systemctl' failed to execute

*   Upgrade of All-in-One on EL6 and FC20 are not going to be supported in 3.6. VDSM and the packages requiring it are not built anymore for EL6 and FC20.

<!-- -->

*   v2v feature on EL 7.1 requires manual installation of virt-v2v packages. See for more details. This workaround will not be needed once EL 7.2 is out

# Install / Upgrade from previous versions

### BETA RELEASE

oVirt 3.6.0 Third Beta release is available since 2015-08-20. In order to install it you've to enable oVirt 3.6 pre release repository.

### Fedora / CentOS / RHEL

In order to install it on a clean system, you need to run (see also [Known Issues](#Known_Issues) above):

`# yum install `[`http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm`](http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm)

If you are upgrading from a previous version, you may have the ovirt-release35 package already installed on your system. You can then install ovirt-release36.rpm as in a clean install side-by-side.

Once ovirt-release36 package is installed, you will have the ovirt-3.6-pre repository and any other repository needed for satisfying dependencies enabled by default.

If you're installing oVirt 3.6.0 Third Beta on a clean host, you should read our [Quick Start Guide](Quick Start Guide).

If you are upgrading from oVirt < 3.5.0, you must first upgrade to oVirt 3.5.0 or later. Please see [oVirt 3.5.3 Release Notes](oVirt 3.5.3 Release Notes) for upgrade instructions.

For upgrading now you just need to execute:

      # yum update "ovirt-engine-setup*"
      # engine-setup

### Debian Jessie

The support for Debian Jessie is highly experimental and implemented as a best effort feature. In order to enable Debian Jessie repositories you need to manually edit **/etc/apt/sources.list** adding:

      # vdsm
      deb `[`http://resources.ovirt.org/pub/ovirt-3.6-pre/debian/`](http://resources.ovirt.org/pub/ovirt-3.6-pre/debian/)` binary/
      deb-src `[`http://resources.ovirt.org/pub/ovirt-3.6-pre/debian/`](http://resources.ovirt.org/pub/ovirt-3.6-pre/debian/)` source/

### oVirt Hosted Engine

If you're going to install oVirt as Hosted Engine on a clean system please follow [Hosted_Engine_Howto#Fresh_Install](Hosted_Engine_Howto#Fresh_Install) guide.

If you're upgrading an existing Hosted Engine setup, please follow [Hosted_Engine_Howto#Upgrade_Hosted_Engine](Hosted_Engine_Howto#Upgrade_Hosted_Engine) guide.

### oVirt Live

A new oVirt Live ISO is available:

[`http://resources.ovirt.org/pub/ovirt-3.6-pre/iso/ovirt-live/el7-beta2.1/`](http://resources.ovirt.org/pub/ovirt-3.6-pre/iso/ovirt-live/el7-beta2.1/)

 - Can't import/clone a snapshot-less VM from export domain without unnecessarily setting copy-collapse to true via REST.
