Windows server 2012: where is my start button??

If you have been using Windows Server OS for a while, the one thing that will strike you most when you login to a Windows server 2012 is that there is no start button!!.. What??..How am I going to manage it?? Microsoft feels that you really dont need a start button, since you can do almost everything from your server  manager or even remotely from your desktop. After all the initial configurations are done, you could also do away with the GUI and go back to server core option.(In server 2012, there is an option to add and remove GUI). So does that mean, you need to learn to live without a start button. Actually no, the start button is very much there .Lets start looking for it. Option 1: There is "charms" bar on the side of your deskop, where you will find a "start" option. You can use the "Windows +C" shortcut to pop out the charms bar Option 2: There is a hidden "start area"in  the bottom left corner of your desktop

Install nested KVM in VMware ESXi 5.1

In this blog, I will explain the steps required to run a nested KVM hypervisor on  Vmware ESXi. The installation of KVM is done on Ubuntu 13.10(64 bit). Note: It is assumed that you have already installed your Ubuntu 13.10 VM in ESXi, and hence we will not look into the Ubuntu installation part. 1) Upgrade VM Hardware version to 9. In my ESXi server, the default VM hardware version was 8. So I had to shutdown my VM and upgrade the Hardware version to 9 to get the KVM hypervisor working. You can right click the VM and select the Upgrade hardware option to do this. 2)In the ESXi host In /etc/vmware edit the 'config' file and add the following setting vhv.enable = "TRUE" 3)Edit the VM settings and go to VM settings > Options  > CPU/MMU Virtualization . Select the Intel EPT option 4) Go to Options->CPUID mask> Advanced-> Level 1, add the following CPU mask level ECX  ---- ---- ---- ---- ---- ---- --H- ---- 5) Open the vmx
