I was working with a XenServer in a complex corporate network environment, and it was not possible for this server to access any samba shares, such as my laptop. I needed to put some ISOs on it, so I decided to create a local storage repository. This way, I would be able to simply -wget an ISO from the web, and then use it locally.
First, SSH into the XenServer and create a directory for the repository;
mkdir -p /var/opt/xen/LocalRepo
Then, tell Xen to create a XenServer Storage Repository at that directory;
xe sr-create name-label=LocalRepo type=iso device-config:location=/var/opt/xen/LocalRepo device-config:legacy_mode=true content-type=iso
Now move to the directory and then wget whatever ISOs you need…
Now you’re cooking with gas!
PS. Make sure to check your free space and make sure your ISOs will fit. This partition is not very big by default.
