[vfio-users] How to let libvirt recognize manual install QEMU?

[Eddie Yen]

OK, for today's test and included 4 times re-install Ubuntu, now I can
build VM with virt-manager, thanks for Francesco's repository.
But not test VFIO bind yet.

Here is a preliminary result:
First, looks like dracut can't install on Ubuntu, and no longer support on
Ubuntu 14.04
Everytime I tried to install dracut by using apt-get, it gets error.
So I guess that I still need to use pci-stub on Ubuntu.
A bit of trouble, but there is no other ways.

Second, I found that I didn't get any OVMF binaries after I installed QEMU,
libvirt, and virt-manager.
Looks like I need to find out. Which versions of OVMF are stable for
WIndows 10 right now?
Because I got movement delay on WIndows 8.1 and 10 with OVMF, and both
guest and host will crash (screen frozen) randomly.

Does anyone had suggestions?
