## Centos 6.4 Example ## Centos 6.6 Example
Once you've setup the above, you are good to go with an example. Once you've setup the above, you are good to go with an example.
To get you started, there is an example config file which you can use: [`examples/centos-6.4.conf`](https://github.com/rdobson/packer-builder-xenserver/blob/master/examples/centos-6.4.conf) To get you started, there is an example config file which you can use:

A brief explanation of what the config parameters mean:
An explanation of what these parameters are doing: * `type` - specifies the builder type. This is 'xenserver-iso', for installing

* `instance_name` - this is the name that should be given to the created VM. * `remote_host` - the IP for the XenServer host being used.
* `instance_memory` - this is the static memory configuration for the VM. * `vm_name` - the name that should be given to the created VM.
* `root_disk_size` - this is the size of the disk the VM should be created with. * `vm_memory` - the static memory configuration for the VM, in MB.
* `iso_name` - this is the name of the ISO visible on a ISO SR connected to the XenServer host. * `disk_size` - the size of the disk the VM should be created with, in MB.
* `iso_name` - the name of the ISO visible on a ISO SR connected to the XenServer host.
* `http_directory` - the path to a local directory to serve up over http. * `http_directory` - the path to a local directory to serve up over http.
* `local_ip` - the IP on the machine you are running packer that your XenServer can connect too.
* `ssh_username` - the username set by the installer for the instance. * `ssh_username` - the username set by the installer for the instance.

# XenServer Builder (from an ISO)
Type: `xenserver-iso`
The XenServer Packer builder is able to create [XenServer](https://www.xenserver.org/)
virtual machines and export them either as an XVA or a VDI, starting from an
ISO image.
The builder builds a virtual machine by creating a new virtual machine
from scratch, booting it, installing an OS, provisioning software within
the OS, then shutting it down. The result of the XenServer builder is a
directory containing all the files necessary to run the virtual machine
portably.
## Basic Example
Here is a basic example. This example is not functional. Even when the
`remote_*` fields have been completed, it will start the OS installer but then
fail because we don't provide the preseed file for Ubuntu to self-install.
Still, the example serves to show the basic configuration:
```javascript
{
"type": "xenserver-iso",
"remote_host": "your-server.example.com",
"remote_username": "root",
"remote_password": "password",
"iso_url": "http://releases.ubuntu.com/12.04/ubuntu-12.04.5-server-amd64.iso",
"iso_checksum": "769474248a3897f4865817446f9a4a53",
"iso_checksum_type": "md5",
"ssh_username": "packer",
"ssh_password": "packer",
"ssh_wait_timeout": "30s",
"shutdown_command": "echo 'packer' | sudo -S shutdown -P now"
}
```
It is important to add a `shutdown_command`. By default Packer forcibly halts the
virtual machine and the file system may not be sync'd. Thus, changes made in a
provisioner might not be saved.
## Configuration Reference
There are many configuration options available for the XenServer builder.
They are organized below into two categories: required and optional. Within
each category, the available options are alphabetized and described.
### Required:
* `iso_checksum` (string) - The checksum for the OS ISO file. Because ISO
files are so large, this is required and Packer will verify it prior
to booting a virtual machine with the ISO attached. The type of the
checksum is specified with `iso_checksum_type`, documented below.
* `iso_checksum_type` (string) - The type of the checksum specified in
`iso_checksum`. Valid values are "none", "md5", "sha1", "sha256", or
"sha512" currently. While "none" will skip checksumming, this is not
recommended since ISO files are generally large and corruption does happen
from time to time.
* `iso_url` (string) - A URL to the ISO containing the installation image.
This URL can be either an HTTP URL or a file URL (or path to a file).
If this is an HTTP URL, Packer will download it and cache it between
runs.
* `remote_host` (string) - The host of the remote machine.
* `remote_username` (string) - The XenServer username used to access the remote machine.
* `remote_password` (string) - The XenServer password for access to the remote machine.
* `ssh_username` (string) - The username to use to SSH into the machine
once the OS is installed.
### Optional:
* `boot_command` (array of strings) - This is an array of commands to type
when the virtual machine is first booted. The goal of these commands should
be to type just enough to initialize the operating system installer. Special
keys can be typed as well, and are covered in the section below on the boot
command. If this is not specified, it is assumed the installer will start
itself.
* `boot_wait` (string) - The time to wait after booting the initial virtual
machine before typing the `boot_command`. The value of this should be
a duration. Examples are "5s" and "1m30s" which will cause Packer to wait
five seconds and one minute 30 seconds, respectively. If this isn't specified,
the default is 10 seconds.
* `clone_template` (string) - The template to clone. Defaults to "Other install
media", this is "other", but you can get _dramatic_ performance improvements
by setting this to the proper value. To view all available values for this
run `xe template-list`. Setting the correct value hints to XenServer how to
optimize the virtual hardware to work best with that operating system.
* `disk_size` (integer) - The size, in megabytes, of the hard disk to create
for the VM. By default, this is 40000 (about 40 GB).
* `floppy_files` (array of strings) - A list of files to place onto a floppy
disk that is attached when the VM is booted. This is most useful
for unattended Windows installs, which look for an `Autounattend.xml` file
on removable media. By default, no floppy will be attached. All files
listed in this setting get placed into the root directory of the floppy
and the floppy is attached as the first floppy device. Currently, no
support exists for creating sub-directories on the floppy. Wildcard
characters (\*, ?, and []) are allowed. Directory names are also allowed,
which will add all the files found in the directory to the floppy.
* `format` (string) - Either "xva" or "vdi_raw", this specifies the output
format of the exported virtual machine. This defaults to "xva". Set to
"vdi_raw" to export just the raw disk image.
* `http_directory` (string) - Path to a directory to serve using an HTTP
server. The files in this directory will be available over HTTP that will
be requestable from the virtual machine. This is useful for hosting
kickstart files and so on. By default this is "", which means no HTTP
server will be started. The address and port of the HTTP server will be
available as variables in `boot_command`. This is covered in more detail
below.
* `http_port_min` and `http_port_max` (integer) - These are the minimum and
maximum port to use for the HTTP server started to serve the `http_directory`.
Because Packer often runs in parallel, Packer will choose a randomly available
port in this range to run the HTTP server. If you want to force the HTTP
server to be on one port, make this minimum and maximum port the same.
By default the values are 8000 and 9000, respectively.
* `install_timeout` (string) - The amount of time to wait after booting the VM
for the installer to shut itself down.
If it doesn't shut down in this time, it is an error. By default, the timeout
is "200m", or over three hours.
* `iso_urls` (array of strings) - Multiple URLs for the ISO to download.
Packer will try these in order. If anything goes wrong attempting to download
or while downloading a single URL, it will move on to the next. All URLs
must point to the same file (same checksum). By default this is empty
and `iso_url` is used. Only one of `iso_url` or `iso_urls` can be specified.
* `output_directory` (string) - This is the path to the directory where the
resulting virtual machine will be created. This may be relative or absolute.
If relative, the path is relative to the working directory when `packer`
is executed. This directory must not exist or be empty prior to running the builder.
By default this is "output-BUILDNAME" where "BUILDNAME" is the name
of the build.
* `platform_args` (object of key/value strings) - The platform args.
Defaults to
```javascript
{
"viridian": "false",
"nx": "true",
"pae": "true",
"apic": "true",
"timeoffset": "0",
"acpi": "1"
}
```
* `shutdown_command` (string) - The command to use to gracefully shut down
the machine once all the provisioning is done. By default this is an empty
string, which tells Packer to just forcefully shut down the machine.
* `shutdown_timeout` (string) - The amount of time to wait after executing
the `shutdown_command` for the virtual machine to actually shut down.
If it doesn't shut down in this time, it is an error. By default, the timeout
is "5m", or five minutes.
* `ssh_host_port_min` and `ssh_host_port_max` (integer) - The minimum and
maximum port to use for the SSH port on the host machine which is forwarded
to the SSH port on the guest machine. Because Packer often runs in parallel,
Packer will choose a randomly available port in this range to use as the
host port.
* `ssh_key_path` (string) - Path to a private key to use for authenticating
with SSH. By default this is not set (key-based auth won't be used).
The associated public key is expected to already be configured on the
VM being prepared by some other process (kickstart, etc.).
* `ssh_password` (string) - The password for `ssh_username` to use to
authenticate with SSH. By default this is the empty string.
* `ssh_port` (integer) - The port that SSH will be listening on in the guest
virtual machine. By default this is 22.
* `ssh_wait_timeout` (string) - The duration to wait for SSH to become
available. By default this is "20m", or 20 minutes. Note that this should
be quite long since the timer begins as soon as the virtual machine is booted.
* `tools_iso_name` (string) - The name of the XenServer Tools ISO. Defaults to
"xs-tools.iso".
* `vm_name` (string) - This is the name of the new virtual
machine, without the file extension. By default this is
"packer-BUILDNAME-TIMESTAMP", where "BUILDNAME" is the name of the build.
* `vm_memory` (integer) - The size, in megabytes, of the amount of memory to
allocate for the VM. By default, this is 1024 (1 GB).
## Differences with other Packer builders
Currently the XenServer builder has some quirks when compared with other Packer builders.
The builder currently only works remotely.
The installer is expected to shut down the VM to indicate that it has completed. This is in contrast to other builders, which instead detect completion by a successful SSH connection. The reason for this difference is that currently the builder has no way of knowing what the IP address of the VM is without starting it on the HIMN.
## Boot Command
The `boot_command` configuration is very important: it specifies the keys
to type when the virtual machine is first booted in order to start the
OS installer. This command is typed after `boot_wait`, which gives the
virtual machine some time to actually load the ISO.
As documented above, the `boot_command` is an array of strings. The
strings are all typed in sequence. It is an array only to improve readability
within the template.
The boot command is "typed" character for character over a VNC connection
to the machine, simulating a human actually typing the keyboard. There are
a set of special keys available. If these are in your boot command, they
will be replaced by the proper key:
* `<bs>` - Backspace
* `<del>` - Delete
* `<enter>` and `<return>` - Simulates an actual "enter" or "return" keypress.
* `<esc>` - Simulates pressing the escape key.
* `<tab>` - Simulates pressing the tab key.
* `<f1>` - `<f12>` - Simulates pressing a function key.
* `<up>` `<down>` `<left>` `<right>` - Simulates pressing an arrow key.
* `<spacebar>` - Simulates pressing the spacebar.
* `<insert>` - Simulates pressing the insert key.
* `<home>` `<end>` - Simulates pressing the home and end keys.
* `<pageUp>` `<pageDown>` - Simulates pressing the page up and page down keys.
* `<wait>` `<wait5>` `<wait10>` - Adds a 1, 5 or 10 second pause before sending any additional keys. This
is useful if you have to generally wait for the UI to update before typing more.
In addition to the special keys, each command to type is treated as a
[configuration template](/docs/templates/configuration-templates.html).
The available variables are:
* `HTTPIP` and `HTTPPort` - The IP and port, respectively of an HTTP server
that is started serving the directory specified by the `http_directory`
configuration parameter. If `http_directory` isn't specified, these will be
blank!
Example boot command. This is actually a working boot command used to start
an Ubuntu 12.04 installer:
```javascript
[
"&lt;esc&gt;&lt;esc&gt;&lt;enter&gt;&lt;wait&gt;",
"/install/vmlinuz noapic ",
"preseed/url=http://{{ .HTTPIP }}:{{ .HTTPPort }}/preseed.cfg ",
"debian-installer=en_US auto locale=en_US kbd-chooser/method=us ",
"hostname={{ .Name }} ",
"fb=false debconf/frontend=noninteractive ",
"keyboard-configuration/modelcode=SKIP keyboard-configuration/layout=USA ",
"keyboard-configuration/variant=USA console-setup/ask_detect=false ",
"initrd=/install/initrd.gz -- &lt;enter&gt;"
]
```
