You should be "ok", however, assuming DB goes out on site 1 and you use
replicated DB on site 2 over VPN - there might be a considerable latency
between the MS on site 1 and DB on site 2 - which can work against you.

I dont know anything about your setup, is it KVM, VMware or XEN?

i'd setup

Site 1:
	2 MS host (fronted by VIP)
	2 DB hosts (replicated to each other and across the VPN as remote slave)
	
Site 2:
	2 MS host (fronted by VIP)
	2 DB hosts (replicated to each other and across the VPN as remote slave)

Also, i would probably not use CloudStack DB HA feature - and setup my
own mysql cluster (my opinion).
