But pure QEMU is very very slow.

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.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into Xen guests.
