+## VM's pros compared to container
+
+1. VM has its own kernel, so it can use a fullfeatured kernel or customise the kernel's
+   configuration, without affecting the host.
+1. VM use a fullfeatured init system, so it can run services like a real machine.
+1. VM can use a fullfeatured network stack, so it can run network services like a real machine. it's
+   very useful for hosting some network services(such as tailscale, dae, etc).
