Creating a Guest Using a Template

4.2 Mounting an ISO

You cannot create a guest from a local hard disk or CD-ROM using the virt-install command-line tool. You can, however, create an installation tree on the host operating system, and mount it as an NFS share. For example

#mkdir -p /el/EL5-x86

#mount -o ro,loop /path/to/Enterprise-R5-x86-dvd.iso /el/EL5-x86

#exportfs *:/el/EL5-x86/

When you create the guest using the virt-install command-line tool, enter the installation location as:

nfs:example.com:/el/EL5-x86

Similarly, to set up an installation tree that can be accessed via HTTP on a server named example.com, enter

#cd /var/www/html

#mkdir EL5-x86

#mount -o ro,loop /path/to/Enterprise-R5-x86-dvd.iso EL5-x86

When you create the guest using the virt-install command-line tool, enter the installation location as:

http://example.com/EL5-x86

4.3 Enabling Registration of Guests with Oracle VM Manager

You can create a guest in Oracle VM Server and manage it using Oracle VM Manager. To add guests created with the virt-install command-line tool, or created manually, you must create the guests with the following configuration:

1.Create a directory for your guest, for example mkdir /OVS/running_pool/myguest

The name of the directory should be the same as the guest name.

2.Create the disk image under the new directory.

The guest is ready to import into Oracle VM Manager.

4.4 Creating a Guest Using a Template

You can create a guest using a template. You can also register a template in Oracle VM Manager and use it to create guests. See the Oracle VM Manager User’s Guide for information about using templates with Oracle VM Manager.

A template is compressed as a .tgz file. A template must contain the basic guest configuration files, vm.cfg and system.img. Templates are often hosted on an FTP or HTTP server. The following example shows you how to download an Oracle Enterprise Linux template from an HTTP server, and use it to create a guest.

1.Download the template into the a directory on the Oracle VM Server computer. This example uses the directory /OVS.

cd /OVS/seed_pool

wget http://example.com/seeds/OVM_EL4U5_X86_HVM.tgz

Uncompress the template:
