I use low end openvz 512MB boxes for all 3 of my (powerdns) DNS servers and an openvz 1GB for my mail server.

Currently we're running SolusVM - It's not doing what we need. We're currently developing a custom control panel built from the ground we expect this to be released Q3-4 of next year with select clien

I was thinking about my own DNS network, but i'll take a look into Rage4.
