VIRTUALIZATION IN UBUNTU

Its been along way in my quest to change from windows operating system to linux. My favourite being ubuntu.

The switch over is never that easy and alot of research is involved to be able to do all that you were used to doing while using windows operating system. Since i am well known for experiments, i could not be that comfortable without virtualization, so i have been experimenting with various virtual machines but hitting a snag somewhere on the way due to some bugs.

Today i had a breakthrough and am glad to share with u how you will be able to run a vitual server on ubuntu.

using sun's virtual box, am now running a virtual machine in my ubuntu and i feel priviledged to share this to let u avoid all the hurstles of research. All the information u need is here.

If after installation the virtual machine fails to start and produce the following error message.
"VirtualBox can't operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_VMX_IN_VMX_ROOT_MODE)."

then perform the following

To disable KVM:

1. Install "bum" (Boot-up Manager): sudo apt-get install bum
2. Start Boot-up Manager (in systems menu) and untick "Full virtualization on i386 and amd64 hardware - kvm"
3. Click Apply

Answer yes to make the change effective right away.
