But pure QEMU is very very slow. Regards Kirby Zhou -----Original Message----- From: Richard W.M.

Thanks very much. BTW, I have a small question, why libguestfs depends on QEMU instead of libvirt? If we take libvirt, we can easily run libguestfs with xen, virtualbox, vmware, etc.
It's considerably more complex than that. However you can already use libguestfs to analyze images from xen, vmware, virtualbox and so on. The fact that qemu is involved behind the scenes doesn't matter -- indeed it's an advantage because qemu's block layer supports many different container formats.
