# 11, VirtIO .
  = para_virtualization VMs performance are better than full VMs .
  = para_virtualization require modifying the VM from inside, Unlike full_virtualization .
  = full_virtualization performance can be as fast as the para_virtualization using VirtIO drivers .
  = Basically, VirtIO is used to enhance storage and networking performance .

  # To configure VirtIO for linux VMs :
    = For linux VMs, Just use the [--os-variant] option, And its okay to use these following parameters too .
    = [--network bridge=br0,model=virtio] .
    = [--disk "vol=my_pool/vm1.qcow2",bus=virtio] .
    = VM should use linux kernel version [2.6.25+] .

  # Fedora VirtIO vs Redhat VirtIO drivers for windows :
    = [https://docs.fedoraproject.org/en-US/quick-docs/creating-windows-virtual-machines-using-virtio-drivers/] .
    = [virtio-win-latest] represent fedora_virtIO drivers .
    = [virtio-win-stable] represent redhat_virtIO drivers .
    = In this course we will use [virtio-win-stable] that centos provides with [dnf] .

  # Also read these intresting pages :
    = Read [https://wiki.archlinux.org/index.php/KVM#List_of_para-virtualized_devices] .
    = Read [https://wiki.archlinux.org/index.php/QEMU#virtio] .

  # To configure VirtIO for windows VMs :
    = Unlinux linux VMs, You need to make your hand dirty .
    = Beside the previous parameters, You have to install VirtIO inside windows manually .
    = In the next lesson we will see how we install VirtIO drivers on windows .
