Ubuntu 12.04 has Hyper-V support Built-in

The latest release of Ubuntu 12.04 LTS (Long Term Support) code named Precise Pangolin from Canonical has many new features as in with any new release improving stability and speed. The interesting addition that will excite Microsoft shops and fans is built in support for Hyper-V eliminating the need to install Microsoft Linux Integration Components inside Ubuntu 12.04 when deployed as a VM

As you can see in the above screenshots the kernel version is 3.2 which has Hyper-V IC modules and detects all Hyper-V synthetic devices like NIC, SCSI storage, has mouse integration and supports multiple vCPUs out of the box.

Hope to see other Linux distributions do the same soon.

How do we heal medicine ? Well Use Checklists

Here is a very interesting TED talk by Dr. Atul Gawande, a Surgeon and Journalist, saying

“Better is possible. It does not take genius. It takes diligence. It takes moral clarity. It takes ingenuity. And above all, it takes a willingness to try”

He says Medicine has become very complex today and we need pit crews with checklists as in other fields of technology to make it better.

 

Have patience and listen to this 19 Mins talk 🙂

Thank you for your time.

RHEL/CentOS 6.2 on Hyper-V 2008 R2 with LIC v3.2

Microsoft Officially supports RedHat, CentOS and SUSE Linux Distributions as VMs running on Hyper-V. Linux Integration Components (LIC) or Linux Integration Services are the software components released by Microsoft that need to be installed on Linux VMs to take full advantage of Hyper-V features.

Linux Integration Components are a set of drivers that enable synthetic device support in supported Linux virtual machines running on Microsoft Hyper-V

These components when installed on Linux mainly provide below features

1. Drivers : Synthetic network controller (NIC), IDE and SCSI storage controllers support
2. Time sync : Clock inside the virtual machine will be in synch with the clock on the Host
3. Integrated Shutdown : Shut down from either Hyper-V Manager or SCVMM
4. Symmetric Multi-Processing (SMP) Support : Support up to 4 virtual processors Per VM
5. Heartbeat : Allows Host to detect if the virtual machine is running and responsive
6. Integrated Mouse Support : Seamless mouse integration when used with the Linux GUI

If Linux IC are not installed one might be presented with one or all of the below errors

CEntOS-00

CEntOS-01

CEntOS-02

Note: This post assumes that one has install CentOS/RHEL/Scientific Linux 6.2 on HyperV and has mounted Linux IC v3.2.iso onto DVD Drive of VM. If not please follow link below this post for Picture guide of CentOS server minimal installation

The documentation available along with LIC v3.2 looks good, but, unfortunately when trying to install you will get an error similar to the below one

ls: cannot access kmod-hyper-v-rhel6-43.1.x86_64.rpm: no such file or directory

ls: cannot access hyper-v-rhel6-43.1.x86_64.rpm: no such file or directory RPM’s are missing

There is a simple work around to this by changing the working directory to the mount point of Linux IC drive and invoking ./install.sh script.

LIC-Error

Below are the commands to run to install Linux IC and reboot, once prompted, as shown in the above screenshot

mount /dev/cdrom /media

cd /media

./install.sh

reboot

When VM is rebooted you will notice that there is no network connectivity to your VM. Follow steps below for configuring network connectivity

vi /etc/sysconfig/network-scripts/ifcfg-eth0

Press i Key on keyboard and type the below lines

DEVICE=”eth0″
ONBOOT=”yes”
HWADDR=
TYPE=Ethernet
BOOTPROTO=dhcp
NAME=”System eth0″

HWADDR is the MAC address of the NIC that can be found from settings menu of VM in Hyper-V (Below screenshot for your reference) and DHCP is the mode of getting IP Address

CEntOS-27b

Now use below Key Combination to save the file and close

Esc

Shift + :

wq

Enter

Use the below commands to edit, Save and close on more file

vi /etc/sysconfig/network

CEntOS-27c

Enter below text, save and close

NETWORKING=yes

CEntOS-27d

Now Run ifup eth0 and you should be connected to network or else take a reboot.

CEntOS-27e

With this our CentOS/RHEL/Scientific Linux 6.2 can take full advantage of Hyper-V synthetic drivers and ready for production 🙂

Interesting Info about Google’s Driverless Car

Here we have interesting info on Google’s Driverless Cars (Presently Experimental) which when available for public, can increase productivity of owners and safety during travel.

Google_driverless_Car

The Google’s Driverless Car is a project by Google to develop technology for driverless cars. Currently the project is being led by Sebastian Thrun, director of the Stanford Artificial Intelligence Laboratory. Below video is a talk of his at TED

Infographic below recently released by Aptus Insurance has few interesting effects of this car on people lives and economy (Click Image to enlarge)
