New description:

 kvm4 is getting fairly old. it's been setup in 2015 and is showing sign of
 old age. for example today it freaked us all out by not returning after a
 reboot right before the holidays (#32801). considering how critical that
 server is (email, puppet, ldap, jenkins, dns, web mirror, all the windows
 buildboxes!) we should start considering a decomissionning process.

 at the very least, we need to get eugeni the heck out of there.

 we have budget to provision another ganeti cluster, so let's use it to
 replace this, and hopefully more. the existing cluster has already taken
 more than its share by taking machines from both kvm1/textile and moly, so
 it's time we provision more hardware for this.

 this requires a new ganeti node (fsn-node-06, #33907).

 machines to be migrated:

  * [x] alberti.torproject.org (LDAP) #33908
  * [x] build-x86-09.torproject.org (build server) - RETIRE - replaced with
 build-x86-11 on gnt-fsn
  * [x] eugeni.torproject.org (email) #32803
  * [x] meronense.torproject.org (metrics) #33909
  * [x] neriniflorum.torproject.org (DNS) #33910
  * [x] oo-hetzner-03.torproject.org (metrics) #33911
  * [x] pauli.torproject.org (puppet) #33912
  * [x] rouyi.torproject.org (jenkins) #33913
  * [x] web-hetzner-01.torproject.org (static mirror) RETIRE
  * [x] weissii.torproject.org (windows build box) #33914
  * [x] winklerianum.torproject.org (windows build box) turned off,
 migrated along weissii, but turned off
  * [x] woronowii.torproject.org (windows build box) turned off, migrated
 along weissii, but turned off

Comment (by anarcat):

 i just retired oo-hetzner-03, the next step here is to retire kvm4 itself,
 it seems.
