here's a quick update wrt. the KVM paravirtualization work: i'm
currently working on KVM/NET, which is a Linux<->Linux virtual network
device driver between the KVM host and the KVM guest. It uses the new
KVM-paravirtualization infrastructure that i've sent to this list
yesterday.
while the code is still a prototype, it's working already and here are
some early TCP bandwidth (bw_tcp from guest to host) performance results
which i'm sure you'll enjoy:
-----------------------------------------------------------
| Native via loopback (mtu=1500) : 235.57 MB/sec |
| Native via loopback (mtu=4000) : 487.12 MB/sec |
-----------------------------------------------------------
| Qemu via RTL-8029 emulation : 2.84 MB/sec |
| KVM via RTL-8029 emulation : 7.41 MB/sec |
-----------------------------------------------------------
| KVM-para via KVM/NET device (mtu=1500) : 303.35 MB/sec |
| KVM-para via KVM/NET device (mtu=4000) : 389.47 MB/sec |
