Re: [libvirt] [PATCH V3 1/2] libxl: drop support for Xen < 4.6

Currently the libxl driver claims support for Xen >= 4.4, but Xen 4.4 and 4.5 are no longer supported upstream. Let's increase the minimum supported Xen version to 4.6 and change the defined LIBXL_API_VERSION to 0x040500, which is the API version defined when Xen 4.6 was released. Since Xen 4.6 contains a pkgconfig file, drop the now unused code that falls back to using LIBVIRT_CHECK_LIB in the absence of pkgconfig file. In addition, bumping the LIBXL_API_VERSION required adjusting the calls to libxl_set_vcpuaffinity to account for the extra parameter in the 0x040500 version of the API. Signed-off-by: Jim Fehlig <jfehlig(a)suse.com&gt; --- I made some other changes to this patch so have not added Michal's ACK from V2. Changes in V3: - Change definition of LIBXL_API_VERSION to 0x040500, the API version set when Xen 4.6 was released - Drop the 'true' parameter to LIBVIRT_CHECK_PKG macro so configure fails if libxl is requested but the devel packages are not installed - Remove a now unused variable and a redundant 'if test with_libxl' check docs/drvxen.html.in | 2 +- m4/virt-driver-libxl.m4 | 27 ++------------------------- src/libxl/libxl_domain.c | 2 +- src/libxl/libxl_driver.c | 2 +- 4 files changed, 5 insertions(+), 28 deletions(-)
