-  * **Virtio** es un estandar de virtualizacion para disco y red que forma parte de los kernel nuevos de GNU/Linux. Asi los guest GNU/Linux utilizan virtio y saben que corren en un entorno virtualizado, mejorando su rendimiento. Es similar a las guest additions de VMWare. Tambien existe en formato de drivers para Window$.+  * **Virtio** son un conjunto de modulos de kernel GNU/Linux que permiten paravirtualizar red y disco. De esa forma, cuando desde el host se usan esos drivers para un guest GNU/Linux, este es consciente de correr en un entorno virtualizado, y coopera con el hipervisor mejorando asi el rendimiento. Virtio es conceptualmente similar a las guest additions de VMWare.

 +http://serverfault.com/questions/457250/kvm-and-libvirt-how-do-i-hotplug-a-new-virtio-disk
 +
 +
 +First of all, you should avoid using virsh attach-disk with its limited amount of options. Instead, I suggest to specify the exact disk format you prefer in a separate, temporary XML file, like this:
 +
 +<code>
 +<disk type='file' device='disk'>
 +  <driver name='qemu' type='qcow2' cache='writeback'/>
 +  <source file='/home/gert/kvm/testdomain-vdb.img'/>
 +  <target dev='vdb' bus='virtio'/>
 +</disk>
 +</code>
 +
 +Before adding it, make sure the hotplug kernel modules are loaded in the guest:
 +
 +  modprobe acpiphp
 +  modprobe pci_hotplug
 +
 +Some distributions, including recent CentOS/RHEL/Fedora have this built-in in the kernel. In this case, check for CONFIG_HOTPLUG_PCI_ACPI. If it's y, then you're all set.
 +
 +Finally, add it to the running VM using
 +
 +  virsh # attach-device [domain] /path/to/disk.xml
 +
 +(optionally, add the --persistent option to let Libvirt update the domain XML definition 'persistent'.)
 +
 +In the guest, the kernel should now be triggered, as can be checked with dmesg:
 +
 +<code>
 +[  321.946440] virtio-pci 0000:00:06.0: using default PCI settings
 +[...]
 +[  321.952782]  vdb: vdb1 vdb2
 +</code>
 +
 +This also works perfectly using the GUI-enabled virt-manager application.
