In many ways, VMware is a ground-breaking technology. VMware manages to fully virtualize the notoriously complex x86 architecture using software techniques only, and to achieve very good performance and stability. As a result, VMware is a very large and complex piece of software. KVM, on the other hand, relies on the new hardware virtualization technologies that have appeared recently. As such, it is very small (about 10,000 lines) and relatively simple. Another big difference is that VMware is proprietary, while KVM is open source.

Xen is a fairly large project, providing both paravirtualization and full virtualization. It is designed as a standalone kernel, which only requires Linux to perform I/O. This makes it rather large, as it has its own scheduler, memory manager, timer handling and machine initialization.

KVM, in contrast, uses the standard Linux scheduler, memory management and other services. This allows the KVM developers to concentrate on virtualization, building on the core kernel instead of replacing it.

QEMU is a user-space emulator. It is a fairly amazing project, emulating a variety of guest processors on several host processors, with fairly decent performance. However, the user-space architecture does not allow it to approach native speeds without a kernel accelerator. KVM recognizes the utility of QEMU by using it for I/O hardware emulation. Although KVM is not tied to any particular user space, the QEMU code was too good not to use—so we used it.

One of my customer asked me how to reuse the old fashioned PC in their Cloud. The question leads to “How to enable VT @ BIOS?”. I wrote the following message to my customer:

Go to BIOS setting, then “Enable” or “Turn On” “Virtualization Technology” like

In Linux, here are steps to enable VT

(source: http://www.redhat.com/..VT_in_BIOS.html)

Verify the virtualization extensions are enabled in BIOS. The BIOS settings for Intel® VT or AMD-V are usually in the Chipset or Processor menus. The menu names may vary from this guide, the virtualization extension settings may be found in Security Settings or other non standard menu names.

Procedure 34.1. Enabling virtualization extensions in BIOS

Reboot the computer and open the system’s BIOS menu. This can usually be done by pressing the delete key, the F1 key or Alt and F4 keys depending on the system.

Select Restore Defaults or Restore Optimized Defaults, and then select Save & Exit.

Power off the machine and disconnect the power supply.

Enabling the virtualization extensions in BIOS

Note: BIOS steps

Many of the steps below may vary depending on your motherboard, processor type, chipset and OEM. Refer to your system’s accompanying documentation for the correct information on configuring your system.

Power on the machine and open the BIOS (as per Step 1).

Open the Processor submenu The processor settings menu may be hidden in the Chipset, Advanced CPU Configuration or Northbridge.

Enable Intel Virtualization Technology (also known as Intel VT) or AMD-V depending on the brand of the processor. The virtualization extensions may be labeled Virtualization Extensions, Vanderpool or various other names depending on the OEM and system BIOS.

Enable Intel VTd or AMD IOMMU, if the options are available. Intel VTd and AMD IOMMU are used for PCI passthrough.

Select Save & Exit.

Power off the machine and disconnect the power supply.

Run cat /proc/cpuinfo | grep vmx svm. If the command outputs, the virtualization extensions are now enabled. If there is no output your system may not have the virtualization extensions or the correct BIOS setting enabled.

IBM announced new offering in Cloud http://www.ibm.com/software/data/infosphere/hadoop/

The comments from CNet:

• IBM chooses Hadoop to analyze big data
• IBM BigSheets to preserve fleeting Web data

One of my colleagues was impressed by the 3D desktop, driven by CompizConfig on my Ubuntu 10.04.

He then asked me how to install one on his ThinkPad T43 machine. Giving the steps:

1. Find a 2G USB key. Click Download @ http://www.ubuntu.com/desktop
2. You’d be given an ISO file. Then follow the step 2 & select “Create a USB stick” @ http://www.ubuntu.com/desktop/get-ubuntu/download
   
3. Restart your Windows then boot from USB key
4. From the same page you can either run Ubuntu from USB to start the installation
   

The debate occurs quite often on how to stack software in Cloud Computing solution (specifically Development & Test Cloud), amongst Service, Software & STG. I don’t complain the variety of software stack, as I like the more choices. I’m going to write out how my architectural solution looks.

I have one philosophy: When I could use OpenSource + Pure Blue software in my solution, I will do it without any hesitation.

IBM Development & Test Cloud solution is based upon Tivoli Service Automation Manager v7.2 for now. There’re 3 types machines in its Cloud environment. 2 of 3, in Managing environment , are Management Server & Administrative Server. The last one, in Managed environment, is the managed system(s).

My only rule to follow is to check the product infocenter, which tells the truth of technology & product. The one is http://tinyurl.com/tivsam (I talk about x only for my current engaged case @ one Telco customer in Beijing)

For Management Server, we have 2 choices on 64 bits x – RHEL5.4 or SLES10.2

For Administrative Server, SLES10.2 is ONLY our choice for Linux. Obviously Microsoft Windows isn’t in my list either. The reason is clear.

For Managed environment on x, we get rid of VMware and we have RHEL5.4 and SLES10.2 (CentOS isn’t in my list, due to lack testing & support)

To combine the above consideration, I use SuSE Linux Enterprise 10.2 in management environment and Redhat Enterprise Linux 5.4 in managed environment.

I placed a lot of effort on Cloud Computing engagement and had tours around the country. Piling my mileage

First off of everthing, I demo my compiz 3D desktop enabled Ubuntu 9.04 to show off how we live in a pure open source environment without having to touch any of Microsoft.

Get back to our topic. Last week, I visited one of largest mobile device / equipment manufacturer to discuss how a Cloud Computing could transform customer’s IT. We spent an hour to talk about Return of Investment (ROI). To list what are supposed in consideration of an ROI

• Hardware
• Image Instance – build, migration, administration
• Software – non-free operating system and hypervisor. If Xen, or KVM being used on LAMP, the cost is close to zero. And all software to build a Cloud environment with licensing and maintenance.
• Labor – build and operate a Cloud environment
• Provisioning Process – time taken to complete provision

Input the above consideration comes out in 3 charts as the following (the data is under a certain assumption and might vary in different environment) :

• Comparison of without- cloud and with- cloud

• Categorized

• Cost in Transformation

The information reflects a scope of ROI to be analyzed and doesn’t have to mean this is a mandatory.
