Oracle VM Installation (Server,Manager,Host and Guest)

Installing Oracle VM Server From a CDROM
Boot the computer with the Oracle VM Server CDROM.The below screens are self explanatory.I assume that you know basics of linux.
While installing virtual server please choose default layout for filesystem and choose static ip for network otherwise you may get problems later.System to Upgrade screen is displayed. Select Reinstall System to overwrite the existing installation.

Oracle recommends you use a default partition layout.

After Installing Oracle Virtual Server please make sure you stop the firewall
#service iptables stop
#chkconfig iptables off

Oracle VM Manager installation

Installing VM guest from a template
Download the template and sftp  to the VM server.

Import the template from VM manager screen

















Lsnr started

Installing from ISO image
If there is no log generated while creating vm guest using ISO file and guest creation gives error then most probably nfs service is not started or firewall is on.
ftp  the ISO image to the OVS server(Host ) and mount it on an empty directory
then execute the following commands to nfs mount it
vi /etc/exports
/mntpt *(ro)
exportfs –ra
service nfs restart
service iptables stop

Post install










After installation we were consuming 4ip’s on the DHCP ,one for the Host and three for the Guest.We wanted to reduce that so we used the following configuration
