Network speed issue for VM

[xyuan240]

Thanks for creatting this project, and I managed to install & run the Mac OS VM in a Ubuntu host.

However, I noticed that the VM network speed is much worse than the host's. (Note, I noticed it by remote connecting to my office machine from the host and guest systems, and I noticed there is quite a difference between them).

I did a bit search and I noticed some people experienced similar issues, and a possible solution is to apply Virtio (http://www.linux-kvm.org/page/Virtio). So my question is that are you aware this issue? And how do I possibly apply Virtio with your image?

Thanks for you attention and any help will be much appreciated!

Weird, I’m getting about 8Gbps on speedtest.net and fast.com (my server has a 10Gbps symmetrical fibre connection)

@MrBenFTW feel free to enlighten us how to boost net speeds :)

Bridged networking or user mode?

Any changes to the qemu arguments?

And VNC only yeah?

I think it is bridged but I am not 100% sure. Like I said, I use subnets with physical/public IPs and fancy routing

I have been looking into this and it seems like MacOS doesn't support virtio for NIC unless you manage to get https://github.com/pmj/virtio-net-osx/ working (but it's out of date).

Apparently creating a bridge is better somehow, but I'm not 100% clear why

@weskerfoot here are the two types of networking
#72

I might add an environment flag to the Docker to allow people to choose between networking types today.

Fixed with #147
