first: no idea why you can't just respond to the list instead break 
"reply-list" and threading for others where duplicate mail get filtered 
and the offlist-reply without headers arrives

which complexity?

a virtual guest is less complex because you don't need a ton of daemons 
for hardware-monitoring, drivers and what not on the guest

you don't need to maintain high ability in each system
you don't need to maintain monitoring in each system

complex are 30 phyiscal servers instead two fat nodes running a 
virtualization cluster with one powerful shared storage

* move you bare metal setup online to new hardware
* replace the complete storage online
* run BIOS/firmware updates without downtimes
* make complete backups of your whole servers
* have 10,20,100 backups of the whole servers (OS, config and data)

all that you can't do with bare metal
