Few switch cases returned failure but didn't report an error. For a situation when the backingStore type='volume' was not translated the following error would occur: $ virsh start VM error: Failed to start domain VM error: An error occurred, but the cause is unknown After this patch: $ virsh start VM error: Failed to start domain VM error: internal error: storage source pool 'tmp' volume 'pull3.qcow2' is not translated Signed-off-by: Peter Krempa <pkrempa@redhat.com> --- src/qemu/qemu_block.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/src/qemu/qemu_block.c b/src/qemu/qemu_block.c index 63116ef5f2..0ee10dd770 100644 --- a/src/qemu/qemu_block.c +++ b/src/qemu/qemu_block.c @@ -1081,8 +1081,14 @@ qemuBlockStorageSourceGetBackendProps(virStorageSourcePtr src, break; case VIR_STORAGE_TYPE_VOLUME: + virReportError(VIR_ERR_INTERNAL_ERROR, + _("storage source pool '%s' volume '%s' is not translated"), + src->srcpool->pool, src->srcpool->volume); + return NULL; + case VIR_STORAGE_TYPE_NONE: case VIR_STORAGE_TYPE_LAST: + virReportEnumRangeError(virStorageType, actualType); return NULL; case VIR_STORAGE_TYPE_NETWORK: @@ -1141,6 +1147,7 @@ qemuBlockStorageSourceGetBackendProps(virStorageSourcePtr src, case VIR_STORAGE_NET_PROTOCOL_NONE: case VIR_STORAGE_NET_PROTOCOL_LAST: + virReportEnumRangeError(virStorageNetProtocol, src->protocol); return NULL; } break; -- 2.24.1
