BHyVe as non root

[Peter Grehan]

Hi Andrea,

  There's 2 issues - firstly, bhyve is new and hasn't had a lot of 
exposure. It's probably safest to restrict it to root for a while to 
avoid exposing non-root users to unforeseen security issues.

  Secondly, the current implementation doesn't tie all resource usage to 
a process. The split of bhyveload/bhyve allows VM memory to be tied to a 
memory object associated with the VM. This complicates the tracking 
system memory usage, which is usually done on a process basis. The fix 
for this, in progress, is to use a single process for a VM, and avoid a 
separate loading process.

  The goal is to allow non-root usage, but there's still a ways to go 
for that.

later,

Peter.
