Virtual Machine agent for hardware virtualized containers

Kata Containers Agent

• Debug mode
• Developer mode
• Enable trace support
• Enable debug console
• cpuset cgroup details

This project implements an agent called kata-agent that runs inside a virtual machine (VM).

The agent manages container processes inside the VM, on behalf of the runtime running on the host.

Debug mode

To enable agent debug output, add the agent.log=debug option to the guest kernel command line.

See the developer guide for further details.

Developer mode

Add agent.devmode to the guest kernel command line to allow the agent process to coredump (disabled by default). Specifying this option implicitly enables debug mode.

Enable trace support

See the tracing guide.

Enable debug console

Add agent.debug_console to the guest kernel command line to allow the agent process to start a debug console. Debug console is only available if bash or sh is installed in the rootfs or initrd image. Developers can connect to the virtual machine using the debug console

cpuset cgroup details

See the cpuset cgroup documentation.
