Preservation of the relative relationship requires us to load the backing store strings from the disk images. With blockdev we stopped detecting the backing chain if it's specified in the XML so the relative links were not loaded at that point. To preserve the functionality from the pre-blockdev without accessing the backing chain unnecessarily during VM startup we must refresh the relative links when relative block commit or block pull is requested. https://bugzilla.redhat.com/show_bug.cgi?id=1818655Signed-off-by: NPeter Krempa <pkrempa@redhat.com> Reviewed-by: NJán Tomko <jtomko@redhat.com>

Format cookies into the backing store string without encryption as they will not be visible on the command line when formatting a 'target' only string.

QEMU requires an extra wrapper object where only the "file" member is populated. This is basically a placeholder for establishing the format layer.

qemuBlockStorageSourceGetFormatRawProps aggregated both formats but since we now have props specific for either of those formats it's unwanted to aggregate the code such way. Split out the 'luks' props formatter into qemuBlockStorageSourceGetFormatLUKSProps. The wrong separation demonstrates istself on formatting of the 'size' and 'offset' attributes for the 'luks' driver which does not conform to the qapi schema. https://bugzilla.redhat.com/show_bug.cgi?id=1814975Signed-off-by: NPeter Krempa <pkrempa@redhat.com> Reviewed-by: NJán Tomko <jtomko@redhat.com>

Many calls of qemuMonitorDelObject don't actually check the return value or report the error from the object deletion itself since they are on cleanup paths. In some cases this can lead to reporting of spurious errors e.g. when qemuMonitorDelObject is used to clean up a possibly pre-existing objects. Add a new argument for qemuMonitorDelObject which controls whether the internals report errors from qemu and fix all callers accordingly. Note that some of the cases on device unplug which check the error code don't in fact propagate the error to the user, but in this case it is important to add the log entry anyways for tracing that the device deletion failed. https://bugzilla.redhat.com/show_bug.cgi?id=1784040Signed-off-by: NPeter Krempa <pkrempa@redhat.com> Reviewed-by: NMichal Privoznik <mprivozn@redhat.com>

libvirt treats 'luks' images as raw+encryption. The logic in qemuBlockStorageSourceCreateFormat skipped the creation if the requested image was raw but didn't take into account the encryption. This manifested itself e.g. when attempting to do a virsh blockcopy with the following XML: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/tmp/enccpy'> <encryption format='luks'> <secret type='passphrase' uuid='0a81f5b2-8403-7b23-c8d6-21ccc2f80d6f'/> </encryption> </source> </disk> Where qemu would report the following error: unable to execute QEMU command 'blockdev-add': Volume is not in LUKS format rather than actually formatting the image first.
