After several attempts and paying extreme attention to what was happening I have come up with the following directions to upgrade from FreeBSD 9.0 to FreeBSD 9.1 on a Rackspace Cloud Server.

Note: If these directions are not followed exactly than you may end up with a still running FreeBSD 9.0 kernel, see “uname -a” to check, or a non-booting system due to the ZFS error, “The kernel fails to mount a ZFS root filesystem with error 2.”

  1. Login as root
  2. cd /root
  3. cp /usr/src/sys/amd64/conf/XENHVM /root/XENHVM
  4. ftp
  5. tar -C / -xvzf src.txz
  6. /usr/sbin/freebsd-update -r 9.1-RELEASE upgrade
  7. /usr/sbin/freebsd-update install
  8. cp /root/XENHVM /usr/src/sys/amd64/conf/XENHVM
  9. cd /usr/src
  10. make buildkernel KERNCONF=XENHVM
  11. make installkernel KERNCONF=XENHVM
  12. shutdown -r now
  13. Login as root
  14. cd /root
  15. /usr/sbin/freebsd-update install
  16. cp /root/XENHVM /usr/src/sys/amd64/conf/XENHVM
  17. cd /usr/src
  18. make buildkernel KERNCONF=XENHVM
  19. make installkernel KERNCONF=XENHVM
  20. shutdown -r now
  21. Hard Reboot
