The initial implementation of native LUKS support within Libvirt introduced a small issue when using a passphrase that is a multiple of 16 bytes in size. This is documented in the following bug and associated patch posted to the Libvirt development list: Unable to use LUKS passphrase that is exactly 16 bytes long https://bugzilla.redhat.com/show_bug.cgi?id=1447297 [libvirt] [PATCH] Fix padding of encrypted data https://www.redhat.com/archives/libvir-list/2017-May/msg00030.html This change introduces a known issue release note and logs an additional breadcrumb when we appear to hit this with pointers to the above. Closes-Bug: #1778044 Change-Id: Id346bce6e47431988cce7001abcf29a9faf2936a
