7ea975efe0 add sub has_feature 
loop over each disk of the vm config file to find if feature is available.

If one of the disk doesn't have the feature, we return undef, else return 1

e18b0b9964 livemigrate : activate xbzrle cache 
This help migrate for vm with of lot of memory access (like database)

live migration tests working:

kvm 1.2 -> kvm 1.2  (xbzrle set on both side)
kvm 1.1 -> kvm 1.2 (xbzrle on target)
kvm 1.1 -> kvm 1.1 (xbzrle not set, qmp command try to set xbzrle but fail)

failing migration

kvm 1.2 -> kvm 1.1 fail, but this is expected.

I tested with a memory benchmark running on the vm with 4GB ram

without xbzrle : migration take 10min, with many network hang
with xbzrle : migration take 1min, no hang

I display xbzrle counters for debug purpose, we can remove them later

cdd2008803 implement virtio-scsi-pci controller 
This add the new virtio-scsi controller support.
http://wiki.qemu.org/Features/VirtioSCSI

Guest need kernel >= 3.4 to support. Windows drivers are also available in last virtio-win

Advantages :

- true scsi controller.(like lsi but a lot faster, around 5% slower than virtio-blk)
- multiples disk by controller (256 for now)
- scsi passthrough
- discard support (great for ssd or thinp storages)
- bootable

Hotplug is not yet available in 1.1. (already available in git)

to define lsi or virtio-scsi-pci controller for scsi disk:

scsihw: lsi|virtio-scsi-pci

default is lsi if not defined.
A megasas controller is comming form qemu 1.2, so we'll able to simply add it in the list of scsi controllers

lsi0 and lsi1 controllers have been renamed to generic scsihw0 and scsihw1,
so we can use them for both lsi or virtio-scsi controller type. (and use same pci slot addr).

2a7993d9ef replace file_size_info by volume_size_info. 
Currently we only find a volume size by using qemu-img info (in file_size_info).

This doesn't works with "virtual" storage like sheepdog,rbd,iscsidirect,nexenta.

This also doesn't work with classic iscsi direct plugin.

So, we need to define a method for each plugin.
