Right, those are LVM volumes that have been created by XenServer and assigned to virtual machines.
 If you want to see what VMs they're attached to you can run various 'xe' commands to see.
 For example, 'xe vm-list' will give you a list of all of your VMs.  If you know the UUID
of the VM already then you can run 'xe vm-disk-list uuid=(uuid)' where (uuid) is the UUID
of the VM in question.

There are VMs roots volumes stored into the Primary storage ?
If it's true, what can I associate this files with VMs hostname or Instance
name ?
