Yes, it was a firewall issue, thanks!

Now I get proper messages on spread start and the IP configured in  
wackamole is configured only on one of the nodes. However,when I  
restart it, spread on the other nodes detects it but wackamole just  
dies with no message in the logs instead of taking over the IP.

The only message I get in the logs is on wackamole starup:
  953 No such interface

Which does not get in the way of bringing up the virtual interface.

Here is my wackamole config:

Spread = 4803 at
SpreadRetryInterval = 5s
Group = wack1

#prefer eth0:
Prefer None

VirtualInterfaces {

Arp-Cache = 90s

Notify {
         # Let's notify our router:
balance {
         AcquisitionsPerRound = all
         interval = 4s
mature = 5s
