[libvirt] [PATCHv6 1/7] qemu: caps: Add capability for change-backing-file command

This command allows to change the backing file name recorded in the metadata of a qcow (or other) image. The capability also notifies that the "block-stream" and "block-commit" commands understand the "backing-file" attribute. --- src/qemu/qemu_capabilities.c | 2 ++ src/qemu/qemu_capabilities.h | 1 + 2 files changed, 3 insertions(+) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index d5f2ef3..0baff2f 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -257,6 +257,7 @@ VIR_ENUM_IMPL(virQEMUCaps, QEMU_CAPS_LAST, "host-pci-multidomain", "msg-timestamp", "active-commit", + "change-backing-file", ); @@ -1416,6 +1417,7 @@ struct virQEMUCapsStringFlags virQEMUCapsCommands[] = { { "blockdev-snapshot-sync", QEMU_CAPS_DISK_SNAPSHOT }, { "add-fd", QEMU_CAPS_ADD_FD }, { "nbd-server-start", QEMU_CAPS_NBD_SERVER }, + { "change-backing-file", QEMU_CAPS_CHANGE_BACKING_FILE }, }; struct virQEMUCapsStringFlags virQEMUCapsEvents[] = { diff --git a/src/qemu/qemu_capabilities.h b/src/qemu/qemu_capabilities.h index 3dae302..89dcc6f 100644 --- a/src/qemu/qemu_capabilities.h +++ b/src/qemu/qemu_capabilities.h @@ -207,6 +207,7 @@ typedef enum { QEMU_CAPS_HOST_PCI_MULTIDOMAIN = 166, /* support domain > 0 in host pci address */ QEMU_CAPS_MSG_TIMESTAMP = 167, /* -msg timestamp */ QEMU_CAPS_ACTIVE_COMMIT = 168, /* block-commit works without 'top' */ + QEMU_CAPS_CHANGE_BACKING_FILE = 169, /* change name of backing file in metadata */ QEMU_CAPS_LAST, /* this must always be the last item */ } virQEMUCapsFlags; -- 1.9.3
