how to used bridged network configuration #144

Closed gkyildirim closed 4 months ago

gkyildirim commented 4 months ago

I'dl like to bridge my vm's interface to my host interface (ie en0). So I can have a vm-to-vm networking. I could not figure out how to do that with vfkit? Is it --device virtio-net,fd ? If so would you please give an example? I have read VZFileHandleNetworkDeviceAttachment but could not figure it out :/

If one must use user mode networking such as gvisor-tap-vsock I would say speed is not much as compared to alternatives. A brief comparison can be found here: https://github.com/lima-vm/lima/issues/2348

I actually have a branch adding bridge networking support https://github.com/cfergeau/vfkit/tree/bridge , this makes use of VZBridgedNetworkDeviceAttachment

However, the code in this branch won't' work as is, as using bridged networking requires an entitlement only Apple can grant:

To use this attachment, your app must have the com.apple.vm.networking entitlement. This entitlement is restricted to developers of virtualization software. To request this entitlement, contact your Apple representative.

Thanks for the info, much appreciated. In place access to this speed would be great IMHO.
