The patch refactors the current ESX storage driver due to following reasons: 1. Given most of the public APIs exposed by the storage driver in Libvirt remains same, ESX storage driver should not implement logic specific for only one supported format (current implementation only supports VMFS). 2. Decoupling interface from specific storage implementation gives us an extensible design to hook implementation for other supported storage formats. This patch refactors the current driver to implement it as a facade pattern i.e. the driver exposes all the public libvirt APIs, but uses backend drivers to get the required task done. The backend drivers provide implementation specific to the type of storage device. File changes: ------------------ esx_storage_driver.c ----> esx_storage_driver.c (base storage driver) | |---> esx_storage_backend_vmfs.c (VMFS backend) One of the task base storage driver need to do is to decide which backend driver needs to be invoked for a given request. This approach extends virStoragePool and virStorageVol to store extra parameters: 1. privateData: stores pointer to respective backend storage driver. 2. privateDataFreeFunc: stores cleanup function pointer. virGetStoragePool and virGetStorageVol are modfiied to accept these extra parameters as user params. virStoragePoolDispose and virStorageVolDispose checks for cleanup operation if available. --- daemon/remote.c | 6 +- src/Makefile.am | 1 + src/conf/storage_conf.c | 3 +- src/datatypes.c | 25 +- src/datatypes.h | 24 +- src/esx/esx_driver.c | 6 +- src/esx/esx_storage_backend_vmfs.c | 1491 ++++++++++++++++++++++++++++++++++++ src/esx/esx_storage_backend_vmfs.h | 30 + src/esx/esx_storage_driver.c | 1319 +++++-------------------------- src/esx/esx_vi.c | 5 +- src/esx/esx_vi.h | 3 +- src/parallels/parallels_storage.c | 24 +- src/remote/remote_driver.c | 6 +- src/storage/storage_driver.c | 28 +- src/test/test_driver.c | 30 +- src/vbox/vbox_tmpl.c | 14 +- 16 files changed, 1843 insertions(+), 1172 deletions(-) create mode 100644 src/esx/esx_storage_backend_vmfs.c create mode 100644 src/esx/esx_storage_backend_vmfs.h diff --git a/daemon/remote.c b/daemon/remote.c index 340d07d..41b8ea8 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -4651,14 +4651,16 @@ get_nonnull_interface(virConnectPtr conn, remote_nonnull_interface iface) static virStoragePoolPtr get_nonnull_storage_pool(virConnectPtr conn, remote_nonnull_storage_pool pool) { - return virGetStoragePool(conn, pool.name, BAD_CAST pool.uuid);
