Only if it can't return the version fall back to the test program scheme. If configure is being called with dedicated flags for the Xen libraries use those instead of the pkg-config output. This will avoid breaking an in-tree Xen build of an old Xen version while a new Xen version is installed on the build machine: pkg-config would pick up the installed Xen config files as the Xen tree wouldn't contain any of them.

The commit also noted that the restriction would be extended to cover operations issued via other xen libraries by subsequent patches. My recent Xen patch [1] added a call to the xenforeignmemory API to allow it to be restricted. This patch now makes use of that new call when the -xen-domid-restrict option is passed.

Only if it can't return the version fall back to the test program scheme. If configure is being called with dedicated flags for the Xen libraries use those instead of the pkg-config output. This will avoid breaking an in-tree Xen build of an old Xen version while a new Xen version is installed on the build machine: pkg-config would pick up the installed Xen config files as the Xen tree wouldn't contain any of them.
