- Volume files are stored in `/nsm/libvirt/volumes/` with naming pattern `<vm_name>-nsm.img`.
- Volumes are attached as `/dev/vdb` using virtio-blk for high performance.
- The script checks available disk space before creating the volume.
- Ownership is set to `socore:socore` with permissions `644`.
- Ownership is set to `qemu:qemu` with permissions `640`.
