[libvirt] [PATCHv3 34/36] 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 08c3d04..05613e5 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -256,6 +256,7 @@ VIR_ENUM_IMPL(virQEMUCaps, QEMU_CAPS_LAST, "usb-kbd", /* 165 */ "host-pci-multidomain", "msg-timestamp", + "change-backing-file", ); @@ -1382,6 +1383,7 @@ 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 d755caa..f6bca5d 100644 --- a/src/qemu/qemu_capabilities.h +++ b/src/qemu/qemu_capabilities.h @@ -206,6 +206,7 @@ enum virQEMUCapsFlags { QEMU_CAPS_DEVICE_USB_KBD = 165, /* -device usb-kbd */ QEMU_CAPS_HOST_PCI_MULTIDOMAIN = 166, /* support domain > 0 in host pci address */ QEMU_CAPS_MSG_TIMESTAMP = 167, /* -msg timestamp */ + QEMU_CAPS_CHANGE_BACKING_FILE = 168, /* change namen of backing file in metadata */ QEMU_CAPS_LAST, /* this must always be the last item */ }; -- 1.9.3
