Note

 

To enable the libvirt memory.usage supporting, you need libvirt version 1.1.1+, qemu version 1.5+, and you need to prepare suitable balloon driver in the image, particularly for Windows guests, most modern Linuxes have it built in. The memory.usage meters can’t be fetched without image balloon driver.
