After i read the back-end storage drivers for libvirt, i cannot find any storage driver like following 128 VIR_STORAGE_POOL_DIR, /* Local directory */ 129 VIR_STORAGE_POOL_FS, /* Local filesystem */ 130 VIR_STORAGE_POOL_NETFS, /* Networked filesystem - eg NFS, GFS, etc */ 131 VIR_STORAGE_POOL_LOGICAL, /* Logical volume groups / volumes */ 132 VIR_STORAGE_POOL_DISK, /* Disk partitions */ 133 VIR_STORAGE_POOL_ISCSI, /* iSCSI targets */ 134 VIR_STORAGE_POOL_SCSI, /* SCSI HBA */ 135 VIR_STORAGE_POOL_MPATH, /* Multipath devices */ 136 VIR_STORAGE_POOL_RBD, /* RADOS Block Device */ 137 VIR_STORAGE_POOL_SHEEPDOG, /* Sheepdog device */ has realized storageVolumeWipe feature. So how could we test this feature? Could anyone please give me some suggestions? Thanks in advance.
