Description of problem

Running: -

kata-runtime 2.1.1
qemu-system-x86_64 5.2.0
containerd 1.4.4-0ubuntu1~20.04.2

I'm trying and failing to consistently see output / diag from the kata-agent running inside the pod sandbox / guest VM.

I'm following the guidance in the Developer Guide

After much experimentation, I think need to "Enable agent debugging" as per the following: -

Confirm the name of the Kata Runtime configuration file: -

export kata_configuration_file=$(kata-runtime env | grep config | awk '{print $3}' | sed 's/\"//g')

Edit the configuration file

vi $kata_configuration_file

and remove the comment from enable_debug = true e.g.: -

[agent.kata]
# If enabled, make the agent display debug-level messages.
# (default: disabled)
enable_debug = true

and remove the comment from debug_console_enabled = true e.g.

# Enable debug console.

# If enabled, user can connect guest OS running inside hypervisor
# through "kata-runtime exec <sandbox-id>" command

debug_console_enabled = true

Create a YAML to define a Nginx pod using Kata

cat << EOF | tee nginx-kata.yaml
apiVersion: v1
kind: Pod
metadata:
  name: nginx-kata
spec:
  runtimeClassName: kata
  containers:
  - name: nginx
    image: nginx
EOF

Create pod

kubectl apply -f nginx-kata.yaml

Grab the sandbox ID and console socket

export sandbox_id=$(ps -ef | grep qemu | egrep -o "sandbox-[^,][^,]*" | sed 's/sandbox-//g' | awk '{print $1}')

export console="/var/run/vc/vm/${sandbox_id}/console.sock"

Access the console socket

socat "stdin,raw,echo=0,escape=0x11" "unix-connect:${console}"

This does appear to work, returning debug such as: -

{"msg":"receive createcontainer, spec: Spec { version: \"1.0.2-dev\", process: Some(Process { terminal: false, console_size: None, user: User { uid: 0, gid: 0, additional_gids: [], username: \"\" }, args: [\"/docker-entrypoint.sh\", \"nginx\", \"-g\", \"daemon off;\"], env: [\"PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin\", \"HOSTNAME=nginx-kata\", \"NGINX_VERSION=1.21.0\", \"NJS_VERSION=0.5.3\", \"PKG_RELEASE=1~buster\", \"KUBERNETES_SERVICE_HOST=10.96.0.1\", \"KUBERNETES_SERVICE_PORT=443\", \"KUBERNETES_SERVICE_PORT_HTTPS=443\", \"KUBERNETES_PORT=tcp://10.96.0.1:443\", \"KUBERNETES_PORT_443_TCP=tcp://10.96.0.1:443\", \"KUBERNETES_PORT_443_TCP_PROTO=tcp\", \"KUBERNETES_PORT_443_TCP_PORT=443\", \"KUBERNETES_PORT_443_TCP_ADDR=10.96.0.1\"], cwd: \"/\", capabilities: Some(LinuxCapabilities { bounding: [\"CAP_CHOWN\", \"CAP_DAC_OVERRIDE\", \"CAP_FSETID\", \"CAP_FOWNER\", \"CAP_MKNOD\", \"CAP_NET_RAW\", \"CAP_SETGID\", \"CAP_SETUID\", \"CAP_SETFCAP\", \"CAP_SETPCAP\", \"CAP_NET_BIND_SERVICE\", \"CAP_SYS_CHROOT\", \"CAP_KILL\", \"CAP_AUDIT_WRITE\"], effective: [\"CAP_CHOWN\", \"CAP_DAC_OVERRIDE\", \"CAP_FSETID\", \

However, this is inconsistent, in that I don't always see output from the socat command.

Reading this Connect to the virtual machine using the debug console the directions in the Enabling debug console for QEMU section advises one to: -

sudo sed -i -e 's/^kernel_params = "\(.*\)"/kernel_params = "\1 agent.debug_console"/g' "${kata_configuration_file}"

which appears to duplicate the debug_console_enabled = true setting ?

I did note a few typos in that page, including: -

For QEMU, connect to the vsock as shown:

$ sudo su -c 'cd /var/run/vc/vm/{sandbox_id} && socat "stdin,raw,echo=0,escape=0x11" "unix-connect:console.sock"

which should read: -

For QEMU, connect to the vsock as shown:

$ sudo su -c 'cd /var/run/vc/vm/${sandbox_id} && socat "stdin,raw,echo=0,escape=0x11" "unix-connect:console.sock"'

i.e. the variable is missing the preceding $ symbol and there's no trailing ' at the end of the command.

I'll create a PR to (hopefully) resolve that ( the missing $ symbol is an issue in 3-4 places ).

Final comment, regarding Start kata-monitor - ONLY NEEDED FOR 2.0.x am I right in believing that kata-monitor is NOT required for Kata 2.0 and beyond e.g. 2.1.1 etc. ?

Expected result

A clear and consistent set of instructions to enable agent / pod sandbox / guest debugging, perhaps with examples.

Actual result

As per the above, inconsistent results from socat when debugging the agent / pod sandbox.
