## Overview

1.1.1

## Design Principles

1
The Waxmill package provides a command-line interface and Java API for creating, configuring, and running bhyve virtual machines. The package follows a number of design principles in order to ensure stability and reliability.
1.1.2

## Plain Text Configuration

1
The Waxmill package stores configuration data for virtual machines in a strict, strongly-typed, versioned XML format. This ensures that virtual machine configurations created by older versions of the Waxmill package can continue to be understood by newer versions of Waxmill, or can be safely migrated to newer formats without any loss of information. Waxmill unconditionally validates all input against a schema (including data that the package wrote itself), and will refuse to work with malformed and/or invalid data. Additionally, the Waxmill package uses a hardened XML parser configuration that is expected to be immune to entity expansion attacks.
1.1.3

## Memory Safety, Type Safety

1
The Waxmill package is written in Java 11, using only a couple of native methods (fork() and execve()), and is therefore likely to be immune to buffer overflows and other memory-safety related bugs that plague the typical present-day system languages. The codebase is, additionally, subjected to extensive static checking on every build. Binary builds are expected to be byte-for-byte reproducible. Extensive use of static typing is used throughout the codebase to enforce invariants statically where possible, and the code is annotated with precondition/invariant/postcondition checks in order to induce bugs to cause early failures instead of silently corrupting state. The codebase also has a high-coverage test suite which exhaustively tests the various API methods and the entire command-line interface.
1.1.4

## Process Supervision

1
The Waxmill package is designed to work under process supervision. The supervision of system services has been a solved problem for decades although many pieces of server software are still not designed to work well under process supervision. Many virtual machine management systems still work with incredibly fragile rc-style scripts and pidfiles that instantly become stale and dangerous on virtual machine crashes. The Waxmill package provides a single command to start a virtual machine in the foreground such that the virtual machine can be supervised using systems such as daemontools, or runit. These tools can guarantee that a virtual machine always starts from a clean slate, and will always be reliably restarted should it crash.

2.1

## Waxmill

1
The primary means by which users use the Waxmill package is via the waxmill command-line tool.
2.2

## Paths And Environment

1
The waxmill command-line tool will attempt to read a configuration file specified by the WAXMILL_CONFIGURATION_FILE environment variable. The configuration file, by convention, should be stored at /etc/waxmill/config.xml. The default configuration file is as follows:
2

### 2.2.2 Configuration File

    <?xml version="1.0" encoding="UTF-8" ?>

    <Configuration xmlns="urn:com.io7m.waxmill.config:1:0">
      <Paths>
        <Path type="ZFSExecutable"
              value="/sbin/zfs"/>
        <Path type="GRUBBhyveExecutable"
              value="/usr/local/sbin/grub-bhyve"/>
        <Path type="BhyveExecutable"
              value="/usr/sbin/bhyve"/>
        <Path type="BhyveCtlExecutable"
              value="/usr/sbin/bhyvectl"/>
        <Path type="CuExecutable"
              value="/usr/bin/cu"/>
        <Path type="VirtualMachineConfigurationDirectory"
              value="/etc/waxmill/vm"/>
        <Path type="IfconfigExecutable"
              value="/sbin/ifconfig"/>
      </Paths>
      <ZFSFilesystems>
        <ZFSFilesystem type="VirtualMachineRuntimeFilesystem"
                       name="storage/vm"
                       mountPoint="/storage/vm"/>
      </ZFSFilesystems>
    </Configuration>

3
The configuration file explicitly specifies the locations of various system utilities [1], and also specifies the location of the virtual machine configuration directory and the virtual machine runtime filesystem. The virtual machine configuration directory is a directory consisting of XML configuration files for individual virtual machines. The virtual machine runtime filesystem is a ZFS filesystem containing one ZFS filesystem per virtual machine, each of which stores resources needed by virtual machines at run-time such as GRUB configuration files, sockets, and lock files. The waxmill tools expect to take complete ownership of the virtual machine runtime filesystem, and can be expected to create arbitrary nested filesystems and volumes as needed.
2.3

## Virtual Machines

1
A virtual machine, in Waxmill, carries a universally-unique identifier that is used to refer to the virtual machine during its entire lifetime. The identifier of a virtual machine cannot be changed after it is defined; this property of identifiers is useful to track virtual machines if they are migrated to new physical machines.
2
A virtual machine is first defined, then configured with one or more devices, then configured with one or more boot configurations, then realized, and finally run.
2.4

## Defining A Virtual Machine

1
Defining a virtual machine involves taking a description of the virtual machine and recording that description in the virtual machine configuration directory. This is typically accomplished using the vm-define command. Once a virtual machine is defined, it will appear in the list of defined virtual machines (which can be inspected using the vm-list command).
2

### 2.4.2 Defining A Virtual Machine

    $ waxmill vm-define \
      --name 'com.io7m.example4' \
      --cpu-count 4 \
      --comment 'An example machine' \
      --memory-gigabytes 1 \
      --memory-megabytes 512

    $ waxmill vm-list
    # ID                                     Name
    800a2dad-3367-4a98-879a-0fac219f55f4     com.io7m.example2
    a866f9e4-f6c1-4ecf-ad49-000925eefa0a     com.io7m.example4
    538a90e4-d50d-4511-8643-ae418279bac4     com.io7m.example
    7c2bcb79-f20c-47fa-812b-8994f17f97b2     com.io7m.example5

3
The definition of the created machine can be exported using the vm-export command. The command will simply print the XML configuration file to the standard output. This can be used to manually inspect the configuration of the machine, or to copy the configuration to a new physical machine.
4

### 2.4.4 Exporting A Virtual Machine

    $ waxmill vm-export --machine a866f9e4-f6c1-4ecf-ad49-000925eefa0a
    <?xml version="1.0" encoding="UTF-8"?>
    <wxm:VirtualMachines xmlns:wxm="urn:com.io7m.waxmill.vm:1:0">
        <wxm:VirtualMachine id="a866f9e4-f6c1-4ecf-ad49-000925eefa0a" name="com.io7m.example4">
            <wxm:Comment>An example machine</wxm:Comment>
            <wxm:CPUTopology sockets="1" threads="1" cores="4"/>
            <wxm:Memory gigabytes="1" megabytes="512"/>
            <wxm:Devices>
                <wxm:HostBridge vendor="UNSPECIFIED">
                    <wxm:DeviceSlot bus="0" slot="0" function="0"/>
                </wxm:HostBridge>
            </wxm:Devices>
            <wxm:BootConfigurations/>
            <wxm:Flags>
                <wxm:Flag name="DisableMPTableGeneration" enabled="false"/>
                <wxm:Flag name="ForceVirtualIOPCIToUseMSI" enabled="false"/>
                <wxm:Flag name="GenerateACPITables" enabled="true"/>
                <wxm:Flag name="GuestAPICIsX2APIC" enabled="false"/>
                <wxm:Flag name="IncludeGuestMemoryInCoreFiles" enabled="false"/>
                <wxm:Flag name="RealTimeClockIsUTC" enabled="false"/>
                <wxm:Flag name="WireGuestMemory" enabled="false"/>
                <wxm:Flag name="ExitCPUOnPAUSE" enabled="true"/>
                <wxm:Flag name="YieldCPUOnHLT" enabled="true"/>
            </wxm:Flags>
        </wxm:VirtualMachine>
    </wxm:VirtualMachines>

5
Similarly, the vm-import command can be used to import one or more virtual machines from a given XML configuration file.
6
bhyve virtual machines have a number of configurable boolean flags. The vm-set command can be used to turn these flags on and off. For example, using PCI passthru devices requires wiring the memory of the guest virtual machine.
2.5

## Adding Devices

1
A virtual machine needs to be configured with one or more devices in order to actually do useful work. Typically, a virtual machine will have one or more storage devices (emulated disks), one or more network devices (emulations of ethernet interfaces), and a console device (to allow access to the operating system console from the host machine). A device is attached to exactly one device slot at any given time. A device slot is a PCI slot value consisting of a 3-tuple (bus, pcislot, function), where bus ∈ [0, 255], pcislot ∈ [0,31], and function ∈ [0,7]. The concrete notation used to denote a device slot is bus:pcislot:function, so the string 1:5:3 denotes a device slot on bus 1, slot 5, function 3. In practice, virtual machines will typically specify all devices to use bus 0 and function 0, and only vary the slot value.
2
The waxmill command-line tool contains various subcommands to create and attach devices to virtual machines.
3

### 2.5.3 Device Commands

- vm-add-ahci-disk
- vm-add-ahci-optical
- vm-add-e1000-network-device
- vm-add-framebuffer-device
- vm-add-lpc-device
- vm-add-passthru
- vm-add-virtio-disk
- vm-add-virtio-network-device

4
The types of devices attached to a virtual machine will depend on the level of support that the guest operating system running on the virtual machine has for virtualization. Operating systems that have explicit support for virtualization (typically every major operating system with a release more recent than about 2007) will perform best using Virtio devices. Older operating systems may need to be presented with the illusion of having access to AHCI devices. Please see the documentation for each of the commands for details.
5
The Waxmill package can optionally automatically manage storage devices backed by ZFS volumes if requested. If, on a virtual machine with ID X, a storage device that is specified to use a zfs-volume backend is attached to slot a:b:c, the Waxmill package will automatically create a ZFS volume at /storage/vm/X/disk-a:b:c (where /storage/vm is the configured virtual machine runtime filesystem) when realizing the virtual machine. This is merely a convenience feature; if the ZFS volume already exists, it will be used and the Waxmill package will not attempt to modify it.
2.6

## Realizing A Virtual Machine

1
Realizing a virtual machine involves reading the description of the virtual machine from the virtual machine configuration directory and then creating any resources that are needed at run-time such as ZFS volumes. The vm-realize command is used to realize virtual machines:
2

### 2.6.2 Realizing A Virtual Machine

    $ waxmill vm-realize \
      --machine a866f9e4-f6c1-4ecf-ad49-000925eefa0a \
      --dry-run true
    /sbin/zfs create -V 10gb storage/vm/a866f9e4-f6c1-4ecf-ad49-000925eefa0a/disk-0_1_0

    $ waxmill vm-realize \
      --machine a866f9e4-f6c1-4ecf-ad49-000925eefa0a

    $ waxmill vm-realize \
      --machine a866f9e4-f6c1-4ecf-ad49-000925eefa0a
    INFO com.io7m.waxmill.cmdline.internal.WXMCommandVMRealize: ZFS volume storage/vm/a866f9e4-f6c1-4ecf-ad49-000925eefa0a/disk-0_1_0 exists and has the correct size

2.7

## Boot Configurations

1
Before a virtual machine can actually be started, it is necessary to define at least one boot configuration. A boot configuration is a named set of instructions that describe how the virtual machine is to be started up. The instructions may include the names of disk images that are to be inserted into emulated optical drives, the type of boot loader to be used, and/or how the boot loader is to locate an operating system kernel on any of the storage devices attached to the virtual machine. Because of the complexity of the information described within a boot configuration, there is no terse command analogous to vm-define that can be used to create a boot configuration. Instead, the boot configuration must be written in an XML file and added to the virtual machine with the vm-update-boot-configurations command. A simple configuration, named install, that boots OpenBSD from an official installer image inserted into the optical drive at device slot 0:4:0 using grub-bhyve might look as follows:
2

### 2.7.2 Example OpenBSD Install Boot Configuration

    <?xml version="1.0" encoding="UTF-8" ?>

    <BootConfigurations xmlns="urn:com.io7m.waxmill.vm:1:0">
      <BootConfigurationGRUBBhyve name="install">
        <BootDiskAttachments>
          <BootDiskAttachment>
            <DeviceSlot bus="0"
                        slot="4"
                        function="0"/>
            <StorageBackendFile path="/storage/images/openbsd/install67.iso"/>
          </BootDiskAttachment>
        </BootDiskAttachments>
        <GRUBBhyveKernelOpenBSD>
          <BSDBootDevice kernelPath="/6.7/amd64/bsd.rd">
            <DeviceSlot bus="0"
                        slot="4"
                        function="0"/>
          </BSDBootDevice>
        </GRUBBhyveKernelOpenBSD>
      </BootConfigurationGRUBBhyve>
    </BootConfigurations>

2.8

## Running A Virtual Machine

1
Once a virtual machine has been realized and has at least one boot configuration, it can be run using the vm-run command:
2

### 2.8.2 Running A Virtual Machine

    $ waxmill vm-run \
      --machine 538a90e4-d50d-4511-8643-ae418279bac4 \
      --boot-configuration install
    rdmsr to register 0x140 on vcpu 0
    rdmsr to register 0x34 on vcpu 0
    Unhandled ps2 mouse command 0xe1
    Unhandled ps2 mouse command 0x88

3
The above command attempts to run the virtual machine with ID 538a90e4-d50d-4511-8643-ae418279bac4, using the boot configuration named run. The waxmill command-line tool process is replaced with that of the bhyve virtual machine, and the bhyve process continues to run in the foreground until the user shuts it down. The vm-run command is designed to be executed by a process supervision system.
2.9

## Process Supervision

1
The Waxmill package is designed to be usable in environments that use a process supervision system. For example, assuming a virtual machine 3bab9914-dfe2-4a37-9c19-c7e9b06c854b has already been configured, it's possible to create runit run and finish scripts such as the following:
2

### 2.9.2 runit run

    #!/bin/sh
    exec /usr/local/bin/waxmill vm-run \
      --machine 3bab9914-dfe2-4a37-9c19-c7e9b06c854b \
      --boot-configuration normal

3

### 2.9.3 runit finish

    #!/bin/sh
    exec /usr/local/bin/waxmill vm-kill \
      --machine 3bab9914-dfe2-4a37-9c19-c7e9b06c854b \

4
These scripts will cause 3bab9914-dfe2-4a37-9c19-c7e9b06c854b to be started and supervised, and the kernel resources associated with the virtual machine will be properly cleaned up when the service is shut down or restarted.

3.1.2

## Verbosity

1
All subcommands accept a --verbose parameter that may be set to one of trace, debug, info, warn, or error. This parameter sets the lower bound for the severity of messages that will be logged. For example, at debug verbosity, only messages of severity debug and above will be logged. Setting the verbosity to trace level effectively causes everything to be logged, and will produce large volumes of debugging output.
2

### 3.1.2.2 Log Levels

Name | Description
--- | ---
trace | All messages greater than or equal to trace level (highest)
debug | All messages greater than or equal to debug level
info | All messages greater than or equal to info level
warn | All messages greater than or equal to warn level
error | All messages greater than or equal to error level

3.1.3

## @ Syntax

1
The waxmill command-line tool uses jcommander to parse command-line arguments, and therefore supports placing command-line arguments into a file, one argument per line, and then referencing that file with @. For example:
2

### 3.1.3.2 @ Syntax

          Default: info
          Possible Values: [trace, debug, info, warn, error]

      The "help" command, executed without arguments, shows the names of all
      commands including the names and types of all of their parameters.

      The "help" command can also be passed the name of a command. Commands
      may include extended help messages such as the one you are reading
      right now.

      Example: waxmill help help

    $ ./waxmill help vm-console
    INFO com.io7m.waxmill.cmdline.Main: Usage: vm-console [options]

      Options:
        --configuration
          The path to the configuration file (environment variable:
          $WAXMILL_CONFIGURATION_FILE)
        --dry-run
          Show the commands that would be executed, but do not execute them.
          Default: false

          Possible Values: [trace, debug, info, warn, error]

      The "vm-console" command attempts to connect to the primary console
      for the given virtual machine. In practice, this means executing the
      "cu"[0] program on the device node that represents the console for
      the VM. The command will fail with a diagnostic error message if the
      virtual machine has no console, or has multiple consoles.

# vm-run

- 3.24. vm-run
  - 3.24.1. Name
  - 3.24.2. Description
  - 3.24.3. Example

3.24.1

## Name

1
vm-run - Start a virtual machine
3.24.2

## Description

1
The vm-run command starts a virtual machine. The command, internally, uses execve() to replace the waxmill process with that of the bhyve virtual machine. The virtual machine stays running in the foreground. The command is intended to be used to start virtual machines under process supervision systems such as daemontools or runit.
2
The vm-run command will, when executed, will first generate and write the necessary configuration files into the virtual machine runtime directory for the given machine, and then generate and execute the necessary shell commands to start the virtual machine. For example, if the selected boot configuration uses GRUB bhyve, the required grub.cfg and device.map files will be generated and saved into the directory. The --dry-run option will cause the command to generate those required files, but will display the shell commands necessary to start the virtual machine on the standard output instead of actually executing them.
3

### 3.24.2.3 Parameters

Parameter | Type | Required | Description
--- | --- | --- | ---
--boot-configuration | Boot Configuration | true | The name of the boot configuration that will be used.
--configuration | Path | false | The path to the configuration file (environment variable: $WAXMILL_CONFIGURATION_FILE)
--dry-run | Boolean | false | Show the commands that would be executed, but do not execute them.
--machine | UUID | true | The ID of the virtual machine
--verbose | Log Level | false | Set the minimum logging verbosity level.
