James:
Thanks for reply. I have got your point.
One more clarification, do we have a plan
to introduce a layer or a kernel module
in uts to leverage underline HW capabilities
for resource management and allocation
per processor usage. Specifically, due to
the maturity of the cores, and core afiliation
and evolution of CMT on Solaris platforms.
How we want to implement every thing per
our S10 SRM and resource pool based
implementation.
I do understand it will be platform specific
and architecture dependent implementation
if it will be implemented. But I do see the value
of doing so from processor resource management
and allocation point of view.
I am thinking from system management perspective
to evaluate the hypervisor etc.
Thanks
Lei

Thanks for the reply. You illustrate the routine sequences
which offer the functionalities which S10 kerenl addresses.
However, there is another aspect of the kernel capability is
to manage the resources such as processor, cores etc. for
kthread invocation and execution. In additon, for LWP and
user land thread resource usage, S10 container SRM and
realated model per zone management would consider hypervisor
can be do ?
I'm not sure what you're asking.
The issues there are fairly similar. The "overhead" of zones is the
same as the "overhead" for having separate processes -- or projects or
tasks, which are the resource management units in Solaris.
Hypervisors are _very_ different in architecture. They generally
involve some sort of layered approach, where the operating system must
make calls (as a "guest") into the HV when real hardware is
manipulated. Those calls involve some (hopefully small) overhead and
translation. No such virtualization is present in Zones.
