[libvirt] [PATCH 0/2] Error out on unsupported formats for vol-wipe

Historically, vol-wipe was created to rewrite volume with either zeros or some algorithm. However for non-raw file-based images rewriting or erasing and recreating them destroys their format. The solution seemed easy -- just delete and rebuild the volume. However we don't store the flags used during creation so we can't safely ensure that the new volume will be the same as the original one. Moreover since commit eec91958b4b0abdbb7ab769f540bcfa72a107c9b we document that it's probably not what users are trying to do. Instead of screwing up the format, let's just disable all the formats that are not supported now.
