AllInOne configuration with fedora 18 and ovirt 3.2 ( ovirt-engine-setup-plugin-allinone “Configure VDSM on this host?” ) ..

In this article, I am gonna write about “ovirt-engine-setup-plugin-allinone ” setup , a nice feature of ovirt. My strings are about ovirt 3.2 and fedora 18.

“All in One” means configuring VDSM on the same host where oVirt-engine is installed, so that VMs can be hosted on the same machine”.

Normally the ovirt manager, hypervisors/hosts, shared storage ..etc used to be on different systems or hardware. How-ever everything on the same piece of hardware can be handy when it comes to a situation like a demo , poc..etc, or maybe a devel environment.

You could also run a system with live cd which can be downloaded from

http://resources.ovirt.org/releases/3.2/tools/

How-ever its a live cd and nothing persistent.

‘All in one’ allows you to have a persisted ovirt setup in single system.

Coooooooool, Isn’t it?

Refer this url for more information on this:

http://www.ovirt.org/Feature/AllInOne

The installation flow consists mainly below steps.

Install ovirt-engine-setup-plugin-allinone rpm.
Start the regular engine-setup procedure.
When asked “Configure VDSM on this host?”, answer yes.
After all answers are provided, the setup will install oVirt-engine and configure VDSM, including local cluster, local datacenter and local host.

I tried ovirt engine all in one setup in my fedora 18 system. For getting the binary, first of all you have to configure the ovirt repo in fedora and then install required package as shown below:

[terminal]
#yum localinstall http://ovirt.org/releases/ovirt-release-fedora.noarch.rpm
[/terminal]

Now, let us install ovirt-engine-setup-plugin-allinone package.

[terminal]
#yum install ovirt-engine-setup-plugin-allinone
[/terminal]

After successful installation of above package, you have to run

[terminal]
#engine-setup
[/terminal]

Above will ask you different inputs and my settings looked similar to below:

[terminal]

oVirt Engine will be installed using the following configuration:
