ESXi create VM utility using python and ssh.

Introduction

This utility is a simple to use comand line tool to create VMs on an ESXi host from from a system running python and ssh. vCenter is not required. This tool is an easy way to automate building VM's from command line or from other testing or automation tools such as Bamboo, Puppet, Saltstack, or Chef.

Usage

Get help using --help option. The defaults will be displayed in the help output.

The only command line required paramater is the VM name (-n), all other command line arguments are optional.

Defaults are stored in your home directory in ~/.esxi-vm.yml. You can edit this file directly, or you can use the tool to update most the defaults by specifying --updateDefaults.

One of the first settings to set and save as defaults is the --Host (-H), --User (-U) and --Password (-P).

Some basic sanity checks are done on the ESXi host before creating the VM. The --verbose (-V) option will give you a little more details in the creation process. If an invalid Disk Stores or Network Interface is specified, the available devices will be shown in the error message. The tool will not show the list of available ISO images, and Guest OS types. CPU, Memory, Virtual Disk sizes are based on ESXi 6.0 limitations.

The --dry (-d) option will go through the sanity checks, but will not create the VM.

By default the Disk Store is set to "LeastUsed". This will use the Disk Store with the most free space (in bytes).

By default the ISO is set to "None". Specify the full path to the ISO image. If you specify just the ISO image filename (no path), the system will attempt to find the ISO image on your DataStores.

By default the Network set set to "None". A full or partial MAC address can be specified. A partial MAC address argument would be 3 Hex pairs which would then be prepended by VMware's OEM "00:50:56".

By default the VM is powered on. If an ISO was specified, then it will boot the ISO image. Otherwise, the VM will attempt a PXE boot if a Network Interface was specified. You could customize the ISO image to specify the kickstart file, or PXE boot using COBBLER, Foreman, Razor, or your favorite provisioning tool.

To help with automated provisioning, the script will output the full MAC address and exit code 0 on success. You can specify --summary to get a more detailed summary of the VM that was created.

Requirements

You must enable ssh access on your ESXi server. Google 'how to enable ssh access on esxi' for instructions. The VMware VIX API tools are not required.

It's HIGHLY RECOMMENDED to use password-less authentication by copying your ssh public keys to the ESXi host, otherwise your ESXi root password could be stored in clear-text in your home directory.

Python and paramiko is a software requirement.

yum -y install python python-paramiko

Example Usage

Running the script for the first time it's recommended to specify your defaults. (ESXi HOST, PASSWORD)

./esxi-vm-create -H esxi -P MySecurePassword -u
Saving new Defaults to ~/.esxi-vm.yml

Create a new VM named testvm01 using all defaults from ~/.esxi-vm.yml.

./esxi-vm-create -n testvm01 --summary
