existing VM or template. XenServer has two mechanisms for copying
VMs and templates, full copy or fast clone:
Full copy makes

hardware-level cloning features for copying the disks from the
existing VM to the new VM. This mode is only supported for
file-backed VMs. Copy-on-Write is designed to save disk space and

You can only copy a VM directly within the same resource pool.
To copy a VM to a server in a different pool, you will need to export the VM and then import it to the
