  1. Working in Centos 7, with systemd
  2. -------
  3. Patches worked, patched configure worked. Build completed. RPM built
  4. Install of Xen worked without any kind of warning or message.
  5.  
  6. Reboot worked, Xen started, and 3 VM auto-started.
  7. However, the libxl error messages are not fixed. My original patch fixed those.
  8. libxl messages are seen in xendomains status, below.
  9.  
  10. In the top here, there is xendomains status still with the noisy error messages. So the xen-init-dom0.service
  11. didn't fix that.
  12.  
  13. Below there is a patch I added to ./tools.configure.ac to fix ./tools/configure
  14. and this was enough to get a build to complete.
  15.
