- Deploy a Baserock system as a *new* VirtualBox virtual machine.
- (Use the `ssh-rsync` write extension to deploy upgrades to an *existing*
- VM)
-
- Connects to HOST via ssh to run VirtualBox's command line management tools.
-
- Parameters:
-
- * location: a custom URL scheme of the form `vbox+ssh://HOST/GUEST/PATH`,
- where:
- * HOST is the name of the host on which VirtualBox is running
- * GUEST is the name of the guest VM on that host
- * PATH is the path to the disk image that should be created,
- on that host. For example,
- `vbox+ssh://alice@192.168.122.1/testsys/home/alice/testys.img` where
- * `alice@192.168.122.1` is the target host as given to ssh,
- **from within the development host** (which may be
- different from the target host's normal address);
- * `testsys` is the name of the new guest VM';
- * `/home/alice/testys.img` is the pathname of the disk image files
- on the target host.
-
- * HOSTNAME=name: the hostname of the **guest** VM within the network into
- which it is being deployed.
-
- * DISK_SIZE=X: **(MANDATORY)** the size of the VM's primary virtual hard
- disk. `X` should use a suffix of `K`, `M`, or `G` (in upper or lower
- case) to indicate kilo-, mega-, or gigabytes. For example,
- `DISK_SIZE=100G` would create a 100 gigabyte virtual hard disk.
-
- * RAM_SIZE=X: The amount of RAM that the virtual machine should allocate
- for itself from the host. `X` is interpreted in the same as for
- DISK_SIZE, and defaults to `1G`.
-
- * VCPUS=n: the number of virtual CPUs for the VM. Allowed values 1-32. Do
- not use more CPU cores than you have available physically (real cores,
- no hyperthreads).
-
- * INITRAMFS_PATH=path: the location of an initramfs for the bootloader to
- tell Linux to use, rather than booting the rootfs directly.
-
- * DTB_PATH=path: **(MANDATORY)** for systems that require a device tree
- binary - Give the full path (without a leading /) to the location of the
- DTB in the built system image . The deployment will fail if `path` does
- not exist.
-
- * BOOTLOADER_INSTALL=value: the bootloader to be installed
- **(MANDATORY)** for non-x86 systems
-
- allowed values =
- - 'extlinux' (default) - the extlinux bootloader will
- be installed
- - 'none' - no bootloader will be installed by `morph deploy`. A
- bootloader must be installed manually. This value must be used when
- deploying non-x86 systems such as ARM.
-
- * BOOTLOADER_CONFIG_FORMAT=value: the bootloader format to be used.
- If not specified for x86-32 and x86-64 systems, 'extlinux' will be used
-
- allowed values =
- - 'extlinux'
-
- * KERNEL_ARGS=args: optional additional kernel command-line parameters to
- be appended to the default set. The default set is:
-
- 'rw init=/sbin/init rootfstype=btrfs \
- rootflags=subvol=systems/default/run \
- root=[name or UUID of root filesystem]'
-
- (See https://www.kernel.org/doc/Documentation/kernel-parameters.txt)
-
- * AUTOSTART=<VALUE> - boolean. If it is set, the VM will be started when
- it has been deployed.
-
- * VAGRANT=<VALUE> - boolean. If it is set, then networking is configured
- so that the VM will work with Vagrant. Otherwise networking is
- configured to run directly in VirtualBox.
-
- * HOST_IPADDR=<ip_address> - the IP address of the VM host.
-
- * NETMASK=<netmask> - the netmask of the VM host.
-
- * NETWORK_CONFIG=<net_config> - `net_config` is used to set up the VM's
- network interfaces. It is a string containing semi-colon separated
- 'stanzas' where each stanza provides information about a network
- interface. Each stanza is of the form name:type[,arg=value] e.g.
-
- lo:loopback
- eth0:dhcp
- eth1:static,address=10.0.0.1,netmask=255.255.0.0
-
- An example of the NETWORK_CONFIG parameter (It should be in one line)
-
- `"lo:loopback;eth0:static,address=192.168.100.2,netmask=255.255.255.0;
- eth1:dhcp,hostname=$(hostname)"`
-
- It is useful to configure one interface to use NAT to give the VM access
- to the outside world and another interface to use the Virtual Box host
- adapter to allow you to access the Trove from the host machine.
-
- The NAT interface eth1 is set up to use dhcp, the host-only adapter
- interface is configured statically.
-
- Note: you must give the host-only adapter interface an address that lies
- **on the same network** as the host adapter. So if the host adapter has
- an IP of 192.168.100.1 eth0 should have an address such as
- 192.168.100.42.
-
- The settings of the host adapter, including its IP can be changed either
- in the VirtualBox manager UI
- (https://www.virtualbox.org/manual/ch03.html#settings-network)
- or via the VBoxManage command line
- (https://www.virtualbox.org/manual/ch08.html#idp57572192)
-
- See Chapter 6 of the VirtualBox User Manual for more information about
- virtual networking (https://www.virtualbox.org/manual/ch06.html)

- (See `morph help deploy` for details of how to pass parameters to write
- extensions)
