Hello,
In "Memory Ballon" (
http://www.libvirt.org/formatdomain.html#elementsMemBalloon ) section,
the second XML exemple has an error. Effectively, the documentation
shows the following :
...
<devices>
<watchdog model='virtio'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x02'
function='0x0'/>
</devices>
</domain>
but it should be
...
<devices>
<memballoon model='virtio'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x02'
function='0x0'/>
</memballoon>
</devices>
</domain>
Best regards,
