2. Pre-Installation Checks
Then Check if KVM Can be Installed
With:egrep -c '(vmx|svm)' /proc/cpuinfo
If in Output > 0 then your Processor support Hardware Virtualization!
Make sure virtualization is enabled in BIOS: Enable Intel VT/AMD-V Guide!Now again, Install the needed Tool:sudo apt install cpu-checker
And then Verify it:
kvm-ok
If it’s Good you will see:
INFO: /dev/kvm exists KVM acceleration can be used
Finally, if the answer is negative you can still use KVM but only in a Slow mode…

3. Installing KVM
Now you are Ready to Install KVM on Ubuntu System
Now KVM should already be there, to Check for it try to load the Kernel Module:modprobe kvm
Again on Intel Processors:
modprobe kvm_intel
But for AMD instead:
modprobe kvm_amd
Last, to Add the default Virtualization Frontend managing Stack run:
sudo apt install qemu qemu-system qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils
Following Ubuntu Documentation about KVM related Packages:
- libvirt-bin provides libvirtd which you need to administer qemu and kvm instances using libvirt
- qemu & qemu-kvm (kvm in Karmic and earlier) are the backend
- ubuntu-vm-builder powerful command line tool for building virtual machines
- bridge-utils provides a bridge from your network to the virtual machines
