gVisor Container on Arm64: Let‘s Talk about Our Progress!
summary
gVisor runs a user‑space kernel on Arm64 using the ptrace platform on Arm64 to intercept syscalls and provide isolation, with the runsc OCI runtime wired into Docker/Kubernetes. Platform work includes rewriting kernel stubs and start/stub processes so a Hello World container actually runs under runsc on Arm64. Filesystem proxy gofer uses 9p (notoriously slow on Arm) and networking relies on gVisor’s netstack; KVM‑style (km) support is incomplete and targeted next.
