HP CloudSystem Matrix 1.x White Paper
HP CloudSystem Foundation and Enterprise Software
This paper describes the process for creating Windows VMDK images
to use with ESXi cluster compute nodes in a CloudSystem
environment. Images are the basis for virtual machine (VM) instances
in HP CloudSystem. You can create and import images from
underlying hypervisor platforms into CloudSystem.
An overview of image concepts
CloudSystem is based on HP Cloud OS and OpenStack technology
HP CloudSystem Foundation is based on HP Cloud OS, which is based on open source OpenStack cloud technology. Images are
uploaded into the CloudSystem image repository, and then users can launch VM instances based on those images. The
OpenStack service that manages images is called ‘Glance’. Images are disk files with pre-installed, bootable Windows or Linux
operating systems. Images may also have pre-installed applications.
Supported image formats and guest operating systems in CloudSystem
CloudSystem supports the guest operating systems that are supported by the underlying hypervisor platform. Consult VMware
and Red Hat documentation for a list of supported guest operating systems.
The following image formats are supported:
For ESXi, images must be in VMDK format.
For KVM, images must be in qcow2 format.
CloudSystem Foundation and CloudSystem Enterprise
The CloudSystem solution is offered in two packages. Foundation is an Openstack-centric IaaS solution, where images are loaded
and used to launch individual VM instances within the OpenStack paradigm. Enterprise is centered on HP Cloud Service
Automation (CSA), offering advanced orchestration, complex service design, and a Market place Portal user experience. When
provisioning VMs defined in an Enterprise service offering against the CloudSystem Foundation provider, you can use images that
were previously uploaded into Foundation.
What makes an image “cloud ready”?
When creating images to use with virtual machines (VMs) in CloudSystem, keep the following details in mind:
Disk partitions must be able to be resized during launch. OpenStack allows users to select multiple ‘flavors’, which
define different sizes of compute resources and boot disks.
The operating system (OS) in the image must support new MAC addresses. Each time an image is launched as a VM,
it is assigned new MAC addresses for virtual NICs.
A user login mechanism must be part of the image’s software and configuration. Typically, Remote Desktop
Protocol (RDP) is used for Windows and Secure Shell (SSH) is used for Linux.
The root/Administrator account can be disabled and logins can be prohibited. This makes it easier to support the
VM instances from central IT.
