Re: [libvirt] [PATCH 01/12] Introduce new public API virNodeDeviceFindByWWN

Since the name (like scsi_host10) is not stable for vHBA, (it can be changed either after recreating or system rebooting), current API virNodeDeviceFindByName is not nice to use for management app in this case. (E.g. one wants to destroy the vHBA whose name has been changed after system rebooting, he has to find out current name first). Later patches will support the persistent vHBA via storage pool, with which one can identify the vHBA stably by the wwnn && wwpn pair. So this new API comes. --- include/libvirt/libvirt.h.in | 5 ++++ src/driver.h | 6 +++++ src/libvirt.c | 45 ++++++++++++++++++++++++++++++++++++++++++ src/libvirt_public.syms | 1 + 4 files changed, 57 insertions(+), 0 deletions(-) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index 09c89c5..b4e1ead 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -3156,6 +3156,11 @@ int virConnectListAllNodeDevices (virConnectPtr conn, virNodeDevicePtr virNodeDeviceLookupByName (virConnectPtr conn, const char *name); +virNodeDevicePtr virNodeDeviceLookupByWWN (virConnectPtr conn, + const char *wwnn, + const char *wwpn, + unsigned int flags);
