I would like to test the 'intnet' networking mode in VirtualBox 4.2.4
(under FreeBSD 9.1-PRERELEASE), running 2 VMs with FreeBSD 9.1-RC3 amd64
After installing your port kernel detected the 'virtio' interface and I
configured the IP on both machines.
I used the 'ttcp' program to test the network performance between
machines and I noticed that average transfer rate is around 6-7 KB/s
(while using eg. the Intel emulator, |82540EM, it's much better, around
Do you have an idea why this is so slow?
And why the if_vtnet network driver isn't provided in GENERIC kernel? Is
it still under development?
