Networking Containers in Multikernel Linux Child Kernels

Mon, 31 Aug 2026 00:00:00 +0000

Giving a Multikernel Linux child network access is not as simple as moving the host’s network interface into it. On Google Compute Engine (GCE), the virtual NIC is also the primary kernel’s route to SSH, metadata, and the guest agent. Assigning that device or its shared controller to a child would put management access at risk.

My first Multikernel Linux experiment on GCE started child kernels with roots that I built ahead of time. That was useful for proving that the kernels could boot, but it was not how a container runtime should consume an image. A runtime should accept the root filesystem that containerd has already prepared and should not become another registry client, layer downloader, or snapshotter.
