No, so far we still use qemu-xen-unstable tree when building Xen in our regular 
testing.
We only have enough resource to cover one qemu tree for Xen.
Which qemu do you suggest in our Xen upstream testing? qemu-xen-unstable or 
pure qemu upstream ?
BTW, do we have some schedule for officially using qemu upstream tree in Xen by 
default in near future (e.g. Xen 4.3)?
