Replied in #clusterlabs, but replying here for the record/archives:

15:31 < digimer> that is written and maintained by pacemaker's author
15:31 < digimer> but it's written using pcs, don't think that's
available on ubuntu.
15:32 < evilrob> right.
15:32 < digimer> for HA, I reallly recommend EL or SUSE
15:32 < digimer> the Deb/Ubuntu stuff isn't maintained well
15:32 < digimer> also, use stonith
15:32 < evilrob> my current plan is to play with it in vagrant under centos
15:32 < digimer> don't, and you cluster will eventually fail spectacularly
15:33 < digimer> centos 7 should be fine
15:33 < digimer> that guide says fedora, but it's 1:1
15:37 < evilrob> ok.  if I can make it all happy under centos, I'll try
top sort out the config on ubuntu.  If that doesn't work, I'll just run
a couple of centos boxen for this I guess.
15:38 < digimer> good plan
15:38 < digimer> at least then, you're only dealing with conversion
instead of also learning
