ploy-virtualbox 1.2.0

Plugin for ploy to provision virtual machines using VirtualBox.

Overview

The ploy_virtualbox plugin provides integration of VirtualBox with ploy.

Installation

ploy_virtualbox is best installed with easy_install, pip or with zc.recipe.egg in a buildout.

Master

The default master for ploy_virtualbox is virtualbox and has the following options:

headless

Whether to start instances in headless mode by default. If not set, the system default is used.

use-acpi-powerbutton

Whether to use acpi power off by default when stopping instances. If not set, the system default is used.

basefolder

The basefolder for VirtualBox data. If not set, the VirtualBox default is used. This varies depending on the OS that ploy is running in. When not provided as absolute path, then it’s relative to ploy.conf.

instance

Name of instance to use to execute VirtualBox commands instead of the default local machine.

Example:

[vb-master:virtualbox]
headless = true

Instances

headless

Whether to start this instance in headless mode. If not set, the setting of the master is used.

use-acpi-powerbutton

Whether to use acpi power off for this instance when stopping. If not set, the setting of the master is used.

basefolder

The basefolder for this instances VirtualBox data. If not set, the setting of the master is used. When not provided as absolute path, then it’s relative to ploy.conf.

no-terminate

If set to yes, the instance can’t be terminated via ploy until the setting is changed to no or removed entirely.

Any option starting with vm- is stripped of the vm- prefix and passed on to VBoxManage. Almost all of these options are passed as is. The following options are handled differently or have some convenience added:

storage

One storage definition per line. See VBoxManage storageattach documentation for details.

If you don’t specify the type, then hdd is used by default.

You don’t have to specify the port, if not set the line number starting at zero is used.

If you don’t set --storagectl then sata is used as default and if that controller doesn’t exist it’s created automatically.

If medium references a local file that path will be passed directly to VBoxManage storageattach.

If it takes the form vb-disk:NAME which refers to a Disk section called NAME that will be used instead.

If it takes the form of an URL, the filename of that URL is assumed to be located at ~/.ploy/downloads/ (this default can be overridden in the [global] section of the configuration file with an entry download_dir). If the file does not exist it will be downloaded.

When using the URL notation it is strongly encouraged to also provide a checksum using the --medium_sha1 key (currently only SHA1 is supported).

Example for using a local ISO image as DVD drive:

storage =
    --type dvddrive --medium ~/downloads/archives/mfsbsd-se-9.2-RELEASE-amd64.iso
    --medium vb-disk:boot

Example for referencing an external URL:

storage =
    --type dvddrive --medium http://mfsbsd.vx.sk/files/iso/10/amd64/mfsbsd-se-10.1-RELEASE-amd64.iso --medium_sha1 03af247c1058a78a251c46ad5a13dc7b84a7ee7d
    --medium vb-disk:boot

hostonlyadapter

If there is a matching Host only interface section, then that is evaluated.

Disk sections

These section allow you to describe how disks should be created.

You can set the size, variant and format options as described in the VBoxManage createhd documentation.

The filename option allows you to set a filename for the disk, the extension is automatically added based on the format option. If you use a relative path, then it’s base is the basefolder setting of the instance.

When the delete option is set to false, the disk is not deleted when the instance using it is terminated. The default is to delete the disk upon instance termination.

Example:

[vb-disk:boot]
size = 102400

Host only interface sections

If you want to use host only network interfaces, then this allows you to make sure your settings are as expected and the interface exists. For now only the ip option is supported. See VBoxManage hostonlyif documentation for details.

Example:

[vb-hostonlyif:vboxnet0]
ip = 192.168.56.1

DHCP

If a vb-dhcpserver section with the same name exists, then it is checked and if needed configured as well. See VBoxManage hostonlyif documentation for details.

Example:

[vb-dhcpserver:vboxnet0]
ip = 192.168.56.2
netmask = 255.255.255.0
lowerip = 192.168.56.100
upperip = 192.168.56.254

The combination of vb-hostonlyif with vb-dhcpserver allows to configure a hostonly network with a deterministic IP address. In the above example you could configure an instance with a static IP address of 192.168.56.99 which would be addressable from the host. The important part is to chose an address that is within the DHCP server network but outside its DHCP pool, which is defined by lowerip and upperip respecitively.

SSH

Depending on the setup we can’t get the IP address or host name automatically.

Unfortunately VirtualBox doesn’t provide a way to see which instance got which IP address from it’s own DHCP servers for example.

If you know which host name or ip address your instance will have, then set the host or ip option as explained above in the hostonly section.

As a workaround you can also setup a NAT port forwarding like this:

vm-nic2 = nat
vm-natpf2 = ssh,tcp,,47022,,22

For this case ploy_virtualbox knows how to get the port and uses it for SSH access via localhost.

If you install the VirtualBox guest additions in your instance, then the status command can show you the current IP address of the instance.

Example config

[vb-master:virtualbox]
# use-acpi-powerbutton = false

[vb-disk:boot]
size = 102400

[vb-hostonlyif:vboxnet0]
ip = 192.168.56.1

[vb-dhcpserver:vboxnet0]
ip = 192.168.56.2
netmask = 255.255.255.0
lowerip = 192.168.56.100
upperip = 192.168.56.254

[vb-instance:foo]
# headless = true
vm-ostype = FreeBSD_64
vm-memory = 512
vm-accelerate3d = off
vm-acpi = on
vm-rtcuseutc = on
vm-boot1 = disk
vm-boot2 = dvd
vm-nic1 = hostonly
vm-hostonlyadapter1 = vboxnet0
vm-nic2 = nat
vm-natpf2 = ssh,tcp,,47022,,22
storage =
    --type dvddrive --medium ~/downloads/archives/mfsbsd-se-9.2-RELEASE-amd64.iso
    --medium vb-disk:boot
