forestii IP address change planned for Ganeti migration

I will soon migrate this virtual machine to the new ganeti cluster. this will involve an IP address change which might affect the service.

Please let me know if there are any problems you can think of. in particular, do let me know if any internal (inside the server) or external (outside the server) services hardcodes the IP address of the virtual machine.

A test instance has been setup. You can test the service by adding the following to your /etc/hosts:

116.202.120.185 forrestii.torproject.org
2a01:4f8:fff0:4f:266:37ff:fe7d:5d12 forrestii.torproject.org

did some tests on the ganeti service, seemed to work fine, host removed from ganeti, DNS lowered, finaly phase begun.

final migration:
