Make sure that there is no error from the above command. Now, check that kvm is really working by running this command: $ virsh -c qemu:///system list $ apt-get install ubuntu-virt-server virt-manager python-vm-builder kvm-ipxe bridge-utils

There are a few software packages you’ll need to install. You’ll probably learn your BIOS might have disabled virtualization anyway when you later try to create a virtual machine and receive a warning about hardware virtualization not being available. Check your BIOS settings to ensure that it is indeed enabled. Note: Despite vmx appearing in mine, the BIOS actually had virtualization disabled. $ egrep '(vmx|svm)' -color=always /proc/cpuinfoĬheck that vmx or svm appears in the output. Next, check that your system has hardware virtualization support. You’ll be prompted for your user password. But it’s easy to get back the root shell: $ sudo -s Ubuntu, like Mac OS X, tries to hide root away from the regular user. Setting Up KVM In Ubuntuįirst, get a root shell. But seeing that 12.04 is marked as LTS (long term support), it will probably stick around longer and many people are likely to stay with it. So I hope this little guide will be useful to some people. This is all supposed to be so straight-forward, but sadly, it was far from a no-brainer. In this post, I’m just going to write-up a mini How-To for virtualization on Ubuntu Linux, using KVM. There are many products out there, for many different variety of use cases. Like, for example, when you have a Linux computer, but also want to run some sort of Windows operating system in that same hardware. There was a time when this was something done on server environments and by computer techies, but these days, end-users with desktops and notebooks are equally using virtualization solutions. One of the most common reasons for end-users to get into virtualization is to be able to run a mix of operating systems on the same physical computer.

PC hardware virtualization is getting quite common place nowadays.
