I compiled from source KVM 0.13.0 and recently also 0.14.0 on intel xeon 54xx and 56xx, on newly installed Ubuntu with vanilla kernel 2.6.37, and when I tried to enable vhost_net (modprobe the module then restart KVM) the emulation was going 100x slower than normal, so I had to disable it. See my old message in this ML "vhost disables kvm acceleration" What did you do to make it work? Did you compile KVM from sources? On what kernel? AMD or Intel? Also, are you not using libvirt maybe?
