Great, thanks for testing.

I need to figure out how to automatically select which guests are
capable of a cooperative resume and which are not.

Are you saying that you don't see the "failed for domain %u" message
immediately after the xc_domain_resume call?

+    if (xc_domain_resume(ctx->xch, domid, 1)) {
          LIBXL__LOG_ERRNO(ctx, LIBXL__LOG_ERROR,
                          "xc_domain_resume failed for domain %u",
                          domid);

That would be pretty odd...

Ian.
