The + structures in the array consist of the following fields: image name, type, read-only flag, creation + time, modification time, current disk space, and image object path.</para> + + <para><function>CreateMachine()</function> may be used to register a new virtual machine or container + with <command>systemd-machined</command>, creating a scope unit for it. It accepts the following arguments: a + machine name chosen by the registrar, an optional UUID as a 32 byte array, a string that identifies the + service that registers the machine, a class string, the PID of the leader process of the machine, an + optional root directory of the container, and an array of additional properties to use for the scope + registration. The virtual machine name must be suitable as a hostname, and hence should follow the usual + DNS hostname rules, as well as the Linux hostname restrictions. Specifically, only 7 bit ASCII is + permitted, a maximum length of 64 characters is enforced, only characters from the set + <literal>a-zA-Z0-9-_.</literal> are allowed, the name may not begin with a dot, and it may not contain + two dots immediately following each other. Container and VM managers should ideally use the hostname + used internally in the machine for this parameter. This recommendation is made in order to make the + machine name naturally resolvable using + <citerefentry><refentrytitle>nss-mymachines</refentrytitle><manvolnum>8</manvolnum></citerefentry>. If + a container manager needs to embed characters outside of the indicated range, escaping is required, + possibly using <literal>_</literal> as the escape character. Another (somewhat natural) option would be + to utilize Internet IDNA encoding. The UUID is passed as a 32 byte array or, if no suitable UUID is + available, an empty array (zero length) or zeroed out array shall be passed. The UUID should identify + the virtual machine/container uniquely and should ideally be the same UUID that + <filename>/etc/machine-id</filename> in the VM/container is initialized from. The service string can be + free-form, but it is recommended to pass a short lowercase identifier like + <literal>systemd-nspawn</literal>, <literal>libvirt-lxc</literal> or similar. The class string should + be either <literal>container</literal> or <literal>vm</literal> indicating whether the machine to + register is of the respective class. The leader PID should be the host PID of the init process of the + container or the encapsulating process of the VM. If the root directory of the container is known and + available in the host's hierarchy, it should be passed. Otherwise, pass the empty string instead. Finally, the + scope properties are passed as array in the same way as to PID1's + <function>StartTransientUnit()</function> method. Calling this method will internally register a transient scope + unit for the calling client (utilizing the passed scope_properties) and move the leader PID into + it. The method returns an object path for the registered machine object that implements the + <interfacename>org.freedesktop.machine1.Machine</interfacename> interface (see below). Also see the + <ulink url="https://www.freedesktop.org/wiki/Software/systemd/ControlGroupInterface">New Control Group + Interfaces</ulink> for details about scope units and how to alter resource control settings on the + created machine at runtime.</para> + + <para><function>RegisterMachine()</function> is similar to <function>CreateMachine()</function>. + However, it only registers a machine and does not create a scope unit for it. Instead, the caller's unit is + registered. We recommend to only use this method for container or VM managers that are run + multiple times, one instance for each container/VM they manage, and are invoked as system + services.</para> + + <para><function>CreateMachineWithNetwork()</function> and + <function>RegisterMachineWithNetwork()</function> are similar to <function>CreateMachine()</function> + and <function>RegisterMachine()</function> but take an extra argument: an array of network interface + indices that point towards the virtual machine or container. The interface indices should reference one + or more network interfaces on the host that can be used to communicate with the guest. Commonly, the + passed interface index refers to the host side of a "veth" link (in case of containers), a + "tun"/"tap" link (in case of VMs), or the host side of a bridge interface that bridges access to the + VM/container interfaces. Specifying this information is useful to enable support for link-local IPv6 + communication to the machines since the scope field of sockaddr_in6 can be initialized by the + specified ifindex. + <citerefentry><refentrytitle>nss-mymachines</refentrytitle><manvolnum>8</manvolnum></citerefentry> + makes use of this information.</para> + + <para><function>KillMachine()</function> sends a UNIX signal to the machine's processes. As its arguments, it takes a + machine name (as originally passed to <function>CreateMachine()</function> or returned by + <function>ListMachines()</function>), an identifier that specifies what precisely to send the signal to (either + <literal>leader</literal> or <literal>all</literal>), and a numeric UNIX signal integer.</para> + + <para><function>TerminateMachine()</function> terminates a virtual machine, killing its processes. It + takes a machine name as its only argument.</para> + + <para><function>GetMachineAddresses()</function> retrieves the IP addresses of a container. This method + returns an array of pairs consisting of an address family specifier (<constant>AF_INET</constant> or + <constant>AF_INET6</constant>) and a byte array containing the addresses. This is only supported for + containers that make use of network namespacing.</para> + + <para><function>GetMachineOSRelease()</function> retrieves the OS release information of a + container. This method returns an array of key value pairs read from the + <citerefentry><refentrytitle>os-release</refentrytitle><manvolnum>5</manvolnum></citerefentry> file in + the container and is useful to identify the operating system used in a container.</para> + + <para><function>OpenMachinePTY()</function> allocates a pseudo TTY in the container and returns a file + descriptor and its path. This is equivalent to transitioning into the container and invoking + <citerefentry project="man-pages"><refentrytitle>posix_openpt</refentrytitle><manvolnum>3</manvolnum></citerefentry>. + </para> + + <para><function>OpenMachineLogin()</function> allocates a pseudo TTY in the container and ensures that + a getty login prompt of the container is running on the other end. It returns the file descriptor of + the PTY and the PTY path. This is useful for acquiring a pty with a login prompt from the + container.</para> + + <para><function>OpenMachineShell()</function> allocates a pseudo TTY in the container, as the specified + user, and invokes the executable at the specified path with a list of arguments (starting from + argv[0]) and an environment block. It then returns the file descriptor of the PTY and the PTY + path.</para> + + <para><function>BindMountMachine()</function> bind mounts a file or directory from the host into the + container. Its arguments consist of a machine name, the source directory on the host, the destination directory in the + container, and two booleans, one indicating whether the bind mount shall be + read-only, the other indicating whether the destination mount point shall be created first, if it is + missing.</para> + + <para><function>CopyFromMachine()</function> copies files or directories from a container into the + host.
