Adding iso repository under XenServer 5.5

If you want to install an OS from a local repository under XenServer 5.5 then you need to do the following. The documentation on how to do this in the xenserver manual is incomplete.

first ssh into the xenserver
mkdir -p /var/opt/xen/iso_import
Copy your ISO images to the /var/opt/xen/iso_import directory using scp.
Create a repository with this command:
xe sr-create name-label=ISOs type=iso device-config:location=/var/opt/xen/iso_import device-config:legacy_mode=true content-type=iso
You then need to attach the ISO library with this command (nicely not mentioned in the citrix documentation)
xe-mount-iso-sr /var/opt/xen/iso_import

You should then be able to create a VM using the .iso
