[OpenIndiana-discuss] Virtualisation in OI 151

[Lou Picciano]

John, 


Zones are a great solution to the model you're proposing. You can get tremendous execution and privilege isolation using zones - they are lightweight and very high-performance. 


In addition, much work has been done lately on KVM - which would be the way to go if you wish to virtualize non-OI OSes. It can run _within_ a zone, and interacts nicely with fundamental OpenIndiana/illumos features, like CrossBow and ZFS. Specifically, you'll want to run OI 151_a5 to get the latest and greatest here. 


Though there had been a linux-branded zone back in the OpenSolaris days, development of zone branding has not continued... KVM may get you all you need.

Hi Folks 



I'm very much a newbie to OpenIndiana and would like to ask about 
Virtualisation. 

My server is at the moment running only as a file server but the plan is to 
virtualise a web server and an FTP server separately in their own zones. 

Is this feasible, and is there any point? My theory (which may be quashed 
shortly) is that by virtualising the servers which would be accessible from 
the outside world I would have huge gains in security. I don't have the 
space for multiple servers and want to remain slightly green by using only 
one if I can get away with it. 



In this situation, what would your recommendations be? Does anyone have 
experience with configuring zones and could you throw me a couple of 
pointers? 



Many thanks and all the best, John.
