Chuck,

I believe Sun is attempting to do what you mention below in Solaris 10 
with zones. We have recently spent some time with both Sun and IBM 
people trying to get a better handle on where they are going with their 
software and hardware technologies...we use both IBM and Sun for our 
UNIX infrastructure (as well as using the 400 platform, LPARS, etc.). 
LPARS obviously have been around for a long time, so when IBM talked 
about enhancements they were making with AIX 5.3 and the Power 5 
platform with regards to virtualization we had a pretty good 
understanding of what they were doing...however Sun's first attempt to 
explain what they were doing with virtualization led to a lot of 
confusion. Last week we met with Sun and someone from the kernel group 
that helped clear our heads. I still have to get my hands around all the 
terminology and features...Solaris 10 is a significant upgrade, far 
greater than say Solaris 8 to Solaris 9. In Solaris 9 you have 
containers, however containers are not protected/isolated instances. It 
still remains to be seen how all these features will pan out in the 
final release, but it sounds promising...and I actually did see some 
this stuff in action...they didn't just talk about it. The cool thing is 
that all of this will work on x86 as well as SPARC.
