Overview
The operation clones the source volume within the same storage pool, It allocates space for the target volume and copies the content across. Various optimizations are applied depending on the source volume format.
virsh vol-clone --pool <storage-pool-name> <source-volume-name> <new-volume-name>
The virsh man page does not explicitly require it, but it is probably better to make sure the source volume is not in use while cloning.
Example
virsh vol-clone --pool main-storage-pool test-volume test-volume.raw virsh vol-list --pool main-storage-pool
