install oVirt engine ( open virtualization manager ) on Fedora 16

There are two components required to use oVirt , oVirt engine ( manage oVirt nodes ) and oVirt nodes.

If you’d like to know more details about oVirt , please check the following URLs.

[ oVirt engine ]

install oVirt engine on Fedora16.

oVirt engine OS info

# cat /etc/redhat-release Fedora release 16 (Verne) # uname -ri 3.2.7-1.fc16.x86_64 x86_64

install the oVirt repository and then install oVirt engine via yum.

# wget http://www.ovirt.org/releases/stable/fedora/16/ovirt-engine.repo -P /etc/yum.repos.d/ `/etc/yum.repos.d/ovirt-engine.repo' saved [125/125]

overt-engine.repo file will be stored under /etc/yum.repos.d directory.

# cat /etc/yum.repos.d/ovirt-engine.repo [ovirt-engine-stable] name=ovirt-engine-stable baseurl=http://www.ovirt.org/releases/stable/fedora/16/ enabled=1 gpgcheck=0

install oVirt engine.

# yum install ovirt-engine -y

set up oVirt engine configuration

run startup script

# engine-setup Error, Not enough available memory on the Host (the minimum requirement is 2 GB and the recommended is 4 GB). Please check log file /var/log/ovirt-engine/engine-setup_2012_02_27_16_01_08.log for more information

nnn , the oVirt engine machine requires 4GB memory at least…

Okay , I’ve added 4GB memory on the oVirt engine machine.

set up.

# engine-setup Error: current locale (ja_JP.UTF-8) is not supported. supported locales are: en_US.UTF-8,en_US.utf-8,en_US.utf8

oh , error .

change locale from JP to US.

# cat /etc/sysconfig/i18n LANG="en_US.UTF-8" #LANG="ja_JP.UTF-8"

reboot the OS

# reboot

confirm the current locale.

# echo $LANG en_US.UTF-8

try again.

(yes|no): no Host fully qualified domain name, note that this name should be fully resolvable

nnn , needs to resolve FQDN for the ovirt engine node.

edit hosts file

# cat /etc/hosts 127.0.0.1   FC16-1.localdomain localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

# ping FC16-1.localdomain -c 1 PING FC16-1.localdomain (127.0.0.1) 56(84) bytes of data. 64 bytes from FC16-1.localdomain (127.0.0.1): icmp_req=1 ttl=64 time=0.031 ms

try again.

A shared storage seems to be required for the setup. ( red lines )

However I have not had the shared storage ( NFS , FC or ISCSI ) in my environment .

So I’m not sure whether or not this setup procedure is correct…

okay ,,, the next step is preparing an ovirt node and manage it via ovrit engine.

stay tuned for the next post on this :)
