Subject: paravirtual drivers?
Date: Thu, 12 Apr 2007 11:38:54 +0200 [thread overview]
Message-ID: <461DFE2E.3020805@wpkg.org> (raw)
As I understand, fully virtualized KVM guests (on Intel VT or AMD-V) can
perform with near native speeds only when it comes to the CPU - because
the things like network or block device are basically emulated.
Among many changes, KVM in 2.6.21 has "Initial paravirtualization
support, which has much faster performance", and is based on KVM-15.
At least two PV drivers are needed:
- network
- block device
What is the state of these PV drivers now? Is it usable on Linux now?
Are Windows PV drivers planned, too? If yes, who is going to take the
lead here (Qumranet, community, not decided yet etc.?).
