It looks like my naming convention on the vSphere side might be to blame. It
looks like "-" is currently a forbidden character for a hostname, unless you
have this working?
I have rebuilt the boxes so many times I wrote a script that configures apt,
installs the latest version of zenbalancer, VMware tools (only the open source
ones, not official), sets up ssh keys and so on.
Always nice to have a pre-built image though so I'll definitely take a look at
your appliance once you have built it. If zen works out I'll eventually be
using several clusters to replace NLB and F5-BigIP (old ones) on our internal
network, some 3000 users over 300 servers in total, plus a bunch of app tier
servers. Plenty of oppertunities for testing new things if you need a
volunteer.
Will the scsi paravirtualisation do much good? I would imagine virtually
everything should be done in memory. If you are hitting swap on a load balancer
you will probably have performance issues. I suppose it will keep host CPU load
down if logging is very verbose though, and it is always nice to have
everything running optimally.

David
