Public Instance Methods
Call
virStorageVolDelete[http://www.libvirt.org/html/libvirt-libvirt.html#virStorageVolDelete]
to delete this volume. This is a destructive operation.
static VALUE libvirt_vol_delete(int argc, VALUE *argv, VALUE v) { VALUE flags; rb_scan_args(argc, argv, "01", &flags); if (NIL_P(flags)) flags = INT2NUM(0); gen_call_void(virStorageVolDelete, conn(v), vol_get(v), NUM2UINT(flags)); }
Call
virStorageVolDownload[http://www.libvirt.org/html/libvirt-libvirt.html#virStorageVolDownload]
to download the content of a volume as a stream.
static VALUE libvirt_vol_download(int argc, VALUE *argv, VALUE v) { VALUE st, offset, length, flags; rb_scan_args(argc, argv, "31", &st, &offset, &length, &flags); if (NIL_P(flags)) flags = INT2NUM(0); gen_call_void(virStorageVolDownload, conn(v), vol_get(v), stream_get(st), NUM2ULL(offset), NUM2ULL(length), NUM2UINT(flags)); }
Call
virStorageVolFree[http://www.libvirt.org/html/libvirt-libvirt.html#virStorageVolFree]
to free the storage volume object. After this call the storage volume
object is no longer valid.
static VALUE libvirt_vol_free(VALUE s) { gen_call_free(StorageVol, s); }
Call
virStorageVolGetInfo[http://www.libvirt.org/html/libvirt-libvirt.html#virStorageVolGetInfo]
to retrieve information about this storage volume.
static VALUE libvirt_vol_info(VALUE v) { virStorageVolInfo info; int r; VALUE result; r = virStorageVolGetInfo(vol_get(v), &info); _E(r < 0, create_error(e_RetrieveError, "virStorageVolGetInfo", conn(v))); result = rb_class_new_instance(0, NULL, c_storage_vol_info); rb_iv_set(result, "@type", INT2NUM(info.type)); rb_iv_set(result, "@capacity", ULL2NUM(info.capacity)); rb_iv_set(result, "@allocation", ULL2NUM(info.allocation)); return result; }
Call
virStorageVolGetKey[http://www.libvirt.org/html/libvirt-libvirt.html#virStorageVolGetKey]
to retrieve the key for this storage volume.
static VALUE libvirt_vol_key(VALUE v) { gen_call_string(virStorageVolGetKey, conn(v), 0, vol_get(v)); }
Call
virStorageVolGetName[http://www.libvirt.org/html/libvirt-libvirt.html#virStorageVolGetName]
to retrieve the name of this storage volume.
static VALUE libvirt_vol_name(VALUE v) { gen_call_string(virStorageVolGetName, conn(v), 0, vol_get(v)); }
Call
virStorageVolGetPath[http://www.libvirt.org/html/libvirt-libvirt.html#virStorageVolGetPath]
to retrieve the path for this storage volume.
static VALUE libvirt_vol_path(VALUE v) { gen_call_string(virStorageVolGetPath, conn(v), 1, vol_get(v)); }
Call
virStoragePoolLookupByVolume[http://www.libvirt.org/html/libvirt-libvirt.html#virStoragePoolLookupByVolume]
to retrieve the storage pool for this volume.
static VALUE libvirt_vol_get_pool(VALUE v) { virStoragePoolPtr pool; pool = virStoragePoolLookupByVolume(vol_get(v)); _E(pool == NULL, create_error(e_RetrieveError, "virStoragePoolLookupByVolume", conn(v))); return pool_new(pool, conn_attr(v)); }
Call
virStorageVolUpload[http://www.libvirt.org/html/libvirt-libvirt.html#virStorageVolUpload]
to upload new content to a volume from a stream.
static VALUE libvirt_vol_upload(int argc, VALUE *argv, VALUE v) { VALUE st, offset, length, flags; rb_scan_args(argc, argv, "31", &st, &offset, &length, &flags); if (NIL_P(flags)) flags = INT2NUM(0); gen_call_void(virStorageVolUpload, conn(v), vol_get(v), stream_get(st), NUM2ULL(offset), NUM2ULL(length), NUM2UINT(flags)); }
Call
virStorageVolWipe[http://www.libvirt.org/html/libvirt-libvirt.html#virStorageVolWipe]
to wipe the data from this storage volume. This is a destructive
operation.
static VALUE libvirt_vol_wipe(int argc, VALUE *argv, VALUE v) { VALUE flags; rb_scan_args(argc, argv, "01", &flags); if (NIL_P(flags)) flags = INT2NUM(0); gen_call_void(virStorageVolWipe, conn(v), vol_get(v), NUM2UINT(flags)); }
Call
virStorageVolGetXMLDesc[http://www.libvirt.org/html/libvirt-libvirt.html#virStorageVolGetXMLDesc]
to retrieve the xml for this storage volume.
static VALUE libvirt_vol_xml_desc(int argc, VALUE *argv, VALUE v) { VALUE flags; rb_scan_args(argc, argv, "01", &flags); if (NIL_P(flags)) flags = INT2NUM(0); gen_call_string(virStorageVolGetXMLDesc, conn(v), 1, vol_get(v), NUM2UINT(flags)); }
