Anyone know when to release include the following features
Paravirtualized networking
Paravirtualized block device KVM Tap network is slower than Xen. Can we
optimize it?

I have such a code in a separate git repository. It is not yet 
production ready.
The next release is a rebase of Rusty code for virtio and some KVM/Qemu 
backend.
It probably be ready in few weeks.

The effort is not big since Rusty has paved most of the way.
Some qemu block handling needs to be done. Again it can happen in 1-2 
months.

Are you talking about PV driver or fully virtualized nic?

Do you know the difference in code to improve the tap network between the
release kvm-44 and the release kvm45?
which modify can improve the tap network performace?How is the work flow of
tap network in kvm?
Why the qemu process use 100% cpu in host?

The change is to trigger a signal to qemu when data is ready on the tap fd.
It will mainly improve latency. The change is not kvm specific and 
applicable to qemu too

This might be a bug. What is the guest doing? Can you run the kvm_stat 
script?
