Re: [libvirt] [PATCH V2] libxl: detect support for save and restore

libxl does not support save, restore, or migrate on all architectures, notably ARM. Detect whether libxl supports these operations using LIBXL_HAVE_NO_SUSPEND_RESUME. If not supported, drop advertisement of <migration_features>. Found by Ian Campbell while improving Xen's OSSTEST infrastructure http://lists.xen.org/archives/html/xen-devel/2014-06/msg02171.html Signed-off-by: Jim Fehlig <jfehlig(a)suse.com&gt; --- Another option for https://www.redhat.com/archives/libvir-list/2014-June/msg01276.html With this one, we even avoid the distasteful double negative :). Compile-tested on x86 only at this point. The ARM build is still slowly grinding away... src/libxl/libxl_conf.c | 4 ++++ src/libxl/libxl_driver.c | 35 +++++++++++++++++++++++++++++++++++ 2 files changed, 39 insertions(+)
