It is not "per processor" virtualization, as you can split a processor/core/threads into different domains, and still you create the LDOMs through software..
It'd take too much typing to properly explain the difference...
...in a nutshell,
LDOMs allow you to assign your hardware to different virtual hosts for exclusive use. Say you have a T5220 with an 8-core CPU. You could create 8 LDOMs and assign a core to each. Each core will be for the exclusive use of the domain you assigned it to, regardless of the load on the other domains. With zones/containers, all zones can use any CPU core/thread that they need when they need it. Limits can be set as far as how much CPU they use, but you cannot specify which CPU/core/thread they are to use.
With LDOMs you get an OBP per domain that can be configured independently from the others. Zones don't have OBPs.
You can "brand" a zone as a Solaris 8 or Solaris 9 zone (and I understand RHEL as well), running an instance of either OS on top of Solaris 10. This is useful in those cases when you are refreshing hardware but app vendors only support their apps on the older OSs. You can't "brand" an LDOM, but you can create a branded zone inside an LDOM.
Root on the global zone can see all of the file systems on each zone.
Root on the primary domain cannot see the files systens on the domains.
I hope this gives you a better idea.

Excel::Template::Container::Loop(3pm) User Contributed Perl Documentation Excel::Template::Container::Loop(3pm)
NAME
Excel::Template::Container::Loop - Excel::Template::Container::Loop
PURPOSE
To provide looping
NODE NAME
LOOP
INHERITANCE
Excel::Template::Container
ATTRIBUTES
o NAME
This is the name of the loop. It's used to identify within the parameter set what variables to expose to the children nodes each
iteration.
CHILDREN
None
EFFECTS
None
DEPENDENCIES
None
USAGE
<loop name="LOOPY">
... Children here ...
</loop>
In the above example, the children nodes would have access to the LOOPY array of hashes as parameters. Each iteration through the array
would expose a different hash of parameters to the children.
These loops work just like HTML::Template's loops. (I promise I'll give more info here!)
There is one difference - I prefer using Perl-like scoping, so accessing of variables outside the LOOP scope from within is perfectly
acceptable. You can also hide outside variables with inner values, if you desire, just like Perl.
