KVM block/network PV drivers

KVM block/network PV drivers

[Alessandro Sardo]

Hello mighty KVM devs,

I have one simple question. What's the status of block/network PV 
drivers for Windows XP/2003?

Thanks,

- Alessandro

PV network:
Currently we have drivers for Linux, they are not yet fully production
quality. The current performance is 450Mbps for 1500 mtu, tcp
connection. There's plenty of low-hanging-fruits to gain performance
here.
As for windows, we will have in the near future; it should be straight
forward implementation once we have the backend on the host & kvm.

PV block device:
First you can use the scsi emulation, it should provide much better
throughput than ide. Second, Arjan van de Ven is working on Linux PV
block device, once he'll publish the code one could build the front end
windows driver.
