Understanding Hardware-Assisted Virtualization

Summary

Hardware-assisted virtualization enables hypervisors to be smaller in size and more efficient when running virtual machine workloads -- compared to software-only solutions. This type of virtualization comes with the tradeoff of high CPU utilization, which impacts performance. However, the newest CPUs are significantly more efficient than their predecessors and utilization has dropped. This results in increased virtual machine performance and higher virtual machine densities per host system.

  • Virtualization with KVM
    KVM continues to gain popularity in the world of Linux – so much so, that it has become Red Hat and Ubuntu's preferred virtualization solution. In contrast to Xen, setting up KVM involves just a couple of steps, and the guest operating systems can run without special patches.
  • Container and hardware e-virtualization under one roof
    The Proxmox distribution specializes in virtualization, letting you deploy and manage virtual servers with OpenVZ and KVM at the same time.
  • Virsh Libvert Tool

    With the command-line tool virsh, a part of the libvirt library, you can query virtual machines to discover their state of health, launch or shut down virtual machines, and perform other tasks – all of which can be conveniently scripted.

  • Live snapshots with Virtual Machine Manager
    In the scope of developing Fedora 20, the live snapshot function, which has long been supported by libvirt, was integrated with the graphical front end. If you prefer to avoid command-line acrobatics à la Virsh, you can now freeze your virtual KVM and Xen machines in VMM at the press of a button.
