Thanks All. I agreed.Currently my HW does not support it. I have ordered new one.<br><br>

</div> why not just go straight to the source and check:<br><br> <a href="http://ark.intel.com/VTList.aspx" target="_blank">http://ark.intel.com/VTList.aspx</a><br><br>that list clearly seems to suggest that the core 2 duo does *not* have<br>
virt support.<br clear="all"></blockquote></div></div>That is correct Sengottuvelan S I checked on that link your machine doest not support vt so the hardware does not support Virtualization but that just means that a hypervisor which needs hardware support i.e. vmx instruction set will not run in your case KVM.<br>
But you can use Xen,QEMU,Virtualbox or VMware also.<br>If you have some specific work or project then that means you need to get another machine.<br>In otherwise case use something other than KVM.<br>Xen might be a bit difficult for you to setup on Ubuntu but if you use CentOS things should work perfectly.<br>
CentOS is RHEL but with proprietary softwares and logo of Red Hat removed.<br>I hope I answered what you wanted to know.<br>The kernel has nothing to do with hardware support.(Correct me if I am wrong)<br>It is the hypervisor which needs support from your cpu in terms of instruction set.<br>
<br>On the same hardware that you have you can give a shot to xen (again if you use CentOS it has a GUI and Xen is shipped on its DVD image precompiled).That way you can do give a try to things that you need.<br>On some places on internet you may get vmware images of Linux preinstalled you can download them and vmware player is freely available from the official site.<br>
That way you can run your virtual machine.<br>As far as this hardware is concerned currently you will not be able to run KVM on it as you <br>/proc/cpuinfo output also says clearly<br>see the following<br><br>

Presence of vmx instruction set means a hypervisor which exclusively depends upon this instruction set will be able to run.In your case KVM depends.<br>The options of BIOS will not help as Roberts Link points it.<br><br>"Your CPU E7200 does not support vt."<br>
This means a hypervisor which needs vmx instruction set to run will not be able to run,but there are other hypervisors<br>or in laymans term virtualization solution which would still run irrespective of hardware supporting vt.<br>
<br>Kernel has not any thing to do to support KVM.<br>When your hypervisor is running then it passes on specific instruction set to the CPU.<br>In old days when vmx support was not available and Virtualization was just evolving,<br>
people used to run Virtual machines ( I am aware of someone doing such stuff a few decades back) using the same instruction set which is found on normal desktops.<br><br>So KVM will not run currently (not because of kernel,but because of hardware support) on your machine.<br>
