Creating Virtual machines on Host Ubuntu Operating System..!!

Hey there..
In this post, i am gonna create virtual machines using KVM (Kernel Virtual Machine) on Ubuntu. KVM only works if your CPU has hardware virtualization support. Check it by running the following command from the terminal:

egrep -c ‘(svm|vmx)’ /proc/cpuinfo

If it results in 0 that means your CPU doesn't support hardware virtualization, while a value 1 or more indicates it does.

Now,  install KVM and its supporting packages by running the command:

sudo apt-get install qemu-kvm virt-manager virt-viewer libvirt-bin

Creating Virtual Machines:
Now, after you got the kvm installed, go to your dash and search for virtual machine manager.

Click on "Create a new virtual machine" option on the upper left side of virtual machine manager.

Click to install from iso image (the very first option which is already selected). Click forward. Now browse for the iso file of the virtual machine you wish to install. Also, choose operating system type and version. In my case , it is Linux operating system and version ubuntu 14.10 (ubuntu utopic) (or later).
Click forward. Choose memory and CPU settings. Click forward. Enable storage and give a enough disk space to the virtual machine. I have given 30 GB space.

Click forward and finish creating the virtual machine. It will start the installation of ubuntu 14.10 virtual machine.
Similarly, you can create any number of virtual machines. Simple click on create a new virtual machine and start the process.

Hope it helps someone to initiate with KVM... Do let me know if it does..!!

Thank you :-)

Fixing "No Wireless Connections" issue after the fresh installation of Ubuntu Utopic 14.10

Hello Everyone..!!
Some days ago, I faced a li'l stupid but a real serious problem after i have installed a fresh Ubuntu 14.10 operating system..!!
 " My system was not showing any of the wireless connections "

Since i was new to Linux at that time.. i have searched really hard to fix my wi-fi issue and resolve it by some simple following steps:

1. First of all i checked pci.id by running the command
    # lspci -nn -d 14e4:
    which showed pci.id= 14e4:4315
2. Update
    # sudo apt-get update
3. Install package firmware-b43-installer
    # sudo apt-get install firmware-b43-installer

and tadaa.. It worked..!! My system is now showing all the wireless connections..!!  

Hope it helps someone to initiate with Ubuntu..!! Do let me know if it does..!!

Thankyou..!! :-)
