Description

By default when we perform create volume form snapshot(which NFS based volume) it internally converting QCOW2 to RAW (RBD )format

1.add nfs based ,RBD based primary storage
2. add storage tags for primary storage and create compute offering for both storages
like for
nfs :normal
RBD :RBD

3. select the nfs based compute offering and deployed a VM
4.Once it successful,select the root partition and perform snapshot
5.once snapshot successful,create a volume from snapshot
here it internally convering into RAW disk(qcow2 format to Raw format) even though snapshot volume is NFS bassed
6.once it created,try to attche newly created data disk to same VM createdin step3

Actual result:

attach volume failed with error code 530 "Failed to attach volume: normalvolume to VM: normal; org.libvirt.LibvirtException: internal error unable to execute QEMU command 'device_add': Duplicate ID 'virtio-disk1' for device"
