Well, first of all if you are not so sure about PowerVM virtualization, I would recommend that you take look at the below site:
https://www.ibm.com/developerworks/w...alization/Home
It also includes lots of videos on how PowerVM works, what LPAR is, what physical CPU and virtual CPU, how PowerVM manages CPU and memory pools, and many more.
There are very good IBM RedBooks as well on PowerVM and virtualization.
Besides the specific features, PowerVM hypervisor is no different than VMWare ESX or Citrix XEN. LPAR is just a fancy name of a "virtual machine". But PowerVM leaves the others out of the race taking full advantage of Power systems in optimized usage of the resources. Thus, very interesting to learn.
Good that you have interest on the platform you are working on. I have a very vague idea about SAS, but I am one of the admins who is responsible for the AIX and other UNIX servers on which SAS runs for our client.
It's always a good idea to be aware of the surroundings!

Hi all,
I'm using python and psutil a library to get system informations like cpu usage (percent) for a given process.
My question is if I have the value in % of the cpu usage how I could get the cpu usage in cycle number I mean not in percent?
Thanks a lot

systemd-detect-virt
SYSTEMD-DETECT-VIRT(1) systemd-detect-virt SYSTEMD-DETECT-VIRT(1)
NAME
systemd-detect-virt - Detect execution in a virtualized environment
SYNOPSIS
systemd-detect-virt [OPTIONS...]
DESCRIPTION
systemd-detect-virt detects execution in a virtualized environment. It identifies the virtualization technology and can distinguish full VM
virtualization from container virtualization.
When executed without --quiet will print a short identifier for the detected virtualization technology. The following technologies are
currently identified: qemu, kvm, vmware, microsoft, oracle, xen, bochs, chroot, uml, openvz, lxc, lxc-libvirt, systemd-nspawn.
If multiple virtualization solutions are used, only the "innermost" is detected and identified. That means if both VM virtualization and
container virtualization are used in conjunction, only the latter will be identified (unless --vm is passed).
OPTIONS
The following options are understood:
-h, --help
Prints a short help text and exits.
--version
Prints a short version string and exits.
-c, --container
Only detects container virtualization (i.e. shared kernel virtualization).
-v, --vm
Only detects VM virtualization (i.e. full hardware virtualization).
-q, --quiet
Suppress output of the virtualization technology identifier.
EXIT STATUS
If a virtualization technology is detected, 0 is returned, a non-zero code otherwise.
