[libvirt] [PATCH] Allow rbd backing stores
Prevents libvirt from treating RBD backing stores as files. Without this patch, creating a domain with a qcow2 overlay on an RBD would fail. This patch essentially extends 9c7c4a4fc533598e59e9a0038ec783e61a38e664, which allows nbd backing stores, to allow rbd backing stores. diff --git a/src/util/storage_file.c b/src/util/storage_file.c index f38aa8e..101518a 100644 --- a/src/util/storage_file.c +++ b/src/util/storage_file.c @@ -589,8 +589,8 @@ virStorageFileMatchesVersion(int format, static bool virBackingStoreIsFile(const char *backing) { - /* Backing store is a network block device */ - if (STRPREFIX(backing, "nbd:")) + /* Backing store is a network block device or Rados block device */ + if (STRPREFIX(backing, "nbd:") || STRPREFIX(backing, "rbd:")) return false; return true; }
