Basic questions about Integrity VMs

Hello,

I am looking into HP-UX 11.31 VMs and I had a few questions.

We own two systems with 11.31 installed on them:
HP 9000 rp3440 (RISC)
- 2gb memory
- 2 processors
HP Integrity rx2660 (Itanium)
- 8gb memory
- 4 processors

Looking at the memory requirements in the Integrity VM Admin Guide [here] it looks like 2gb memory isn't nearly enough to run VMs on, and I don't know if that hardware is even supported, so I'm guessing the hp9000 machine isn't going to cut it (?), but the rx2660 looks good to go. Also vPars don't seem to be supported on the rx2660 which is why I am going the HPVM route.

1) Do HPVMs have completely separate, dedicated resources? I need to set up VMs that do not share resources, such as kernel, CPU, etc.
1b) And if so, is it a 1-to-1 CPU mapping for VMs? (1 CPU for host, leaving me 3 to use for 3 HPVMs)

2) The admin guide and the release notes [here] say the host OS should not have applications running on it. Does this mean I will have to install a fresh copy of 11.31 on my rx2660? Or can I just install patches and update to the required patch version?

3) Speaking of patches, the release notes say I should be running September 2012 (AR1209) release. How do I obtain this patch? HP's software page for the rx2660 [here] does not seem to list any patches, and the 11.31 Installation guide (that I do not have a link to at the moment) says I can run "swa report" to possibly obtain patches (?) however when I run the command, I get the following error:

Code:

=======  12/24/12 18:45:54 PST  BEGIN Report on Issues and New Software
         (user=root)  (jobid=hpitqa-04)

       * Gathering Inventory

         "crl_url" extended option. It may be necessary to disable the CRL
         checking with the "crl_check" option.

=======  12/24/12 18:46:03 PST  END Report on Issues and New Software failed
         with 1 error. (user=root)  (jobid=hpmachine)

NOTE:    More information may be found in the Software Assistant logfile
         "/var/opt/swa/swa.log".

Is there some other place I am supposed to download patches, and is there any specific method of installing them?

Thank you in advance!

pwr_idle_ctl

pwr_idle_ctl(5) 						File Formats Manual						   pwr_idle_ctl(5)

NAME

       pwr_idle_ctl - control power consumption in idle processors on Integrity platforms

VALUES

   Fail Safe
   Default
   Allowed values
DESCRIPTION

       The  tunable  can be used to dynamically control the power consumption of idle processors on Integrity systems.	The tunable can be changed
       from through where represents the least power saving and represents the maximum power saving in idle processors.   Equal  or  greater  idle
       processor power saving is guaranteed by increasing the value of this tunable.

       When the tunable is set to the power saving feature is turned off.

       This  tunable  is  supported only on Integrity platforms with Intel(R) Itanium(R) Processors 9000 Series and later.  It is not supported on
       PA-RISC platforms.

       This tunable is not supported while running in a Integrity Virtual Machine guest environment.

   Who Is Expected to Change This Tunable?
       System administrators who want to control power utilization on idle processors.

   Restrictions on Changing
       The tunable will not take effect on processors belonging to processor sets whose lcpu attribute is turned ON.

       This tunable is dynamic.

   When Should the Tunable Be Turned On?
       The tunable should be turned on to save power on idle systems.

   What Are the Side Effects of Turning the Tunable On?
       Some workloads may experience performance degradation when the tunable is enabled.

   What Are the Side Effects of Turning the Tunable Off?
       With the tunable turned off, the system administrator may not take advantage of possible power saving on idle systems.

   What Other Tunables Should Be Changed at the Same Time?
       None.

WARNINGS

       All HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases	of
       HP-UX.

       Increase in power savings is not guaranteed with an increase in tunable values in certain environments.

       Enabling this tunable may impact the performance of certain types of workloads.

       Installation  of  optional  kernel  software, from HP or other vendors, may cause changes to tunable parameter values.  After installation,
       some tunable parameters may no longer be at the default or recommended values.  For information about the effects of installation  on  tun-
       able  values,  consult  the documentation for the kernel software being installed.  For information about optional kernel software that was
       factory installed on your system, see at
