here some news for kvm forum 2015 :)
for xbzrle, I think we could enable it by default, as it's has been optimized since this commit:
for compression, slides said that for 10GBE, it's slower with compression.
also for compression, we can configure number of threads and compression level
(BTW, they are a lot of interesting doc for different topic from kvm forum 2015, http://www.linux-kvm.org/page/KVM_Forum_2015)

If we add additional options, there should be a good reason.
For example, why do you want to disable compression or
xbzrle? Any benchmarks?
