A wide range of compatible operating systems
In addition to the Public Image Catalog, which provides system images maintained by OVH, you can build a Private Image Catalog. This means your instances can access operating systems specifically configured to you, or from other publishers.
Import an image from a local file
openstack image create --disk-format qcow2 --file debian.qcow2 debian
Export an image
openstack image save --filename debian.qcow2 debian
OVH can manage several types of virtual disk format, including QCOW2, RAW, VMDK, ISO, AMI/AKI/ARI, VDI and VHD.
Sharing between projects
When managing multiple cloud projects, you can share images from one project to another while keeping them in the same place, with no need to duplicate the image in question.
Simplified importing and exporting
Your system images remain your property. Whether you’re importing or exporting, everything is managed via standard tools, such as the OpenStack CLI or the Horizon interface.
An image’s metadata governs whether or not the image can be used to manage a catalog, or used directly on an instance. As a result, you can define a minimum amount of RAM or disk space required for the image to work properly, and you can also add tags or configure the image properties.
Import from a URL
In order to make it easier to add images to your catalog, you can import system images directly from public URLs. You do not have to perform unnecessary image transfers.
Import from Block Storage
A volume of the Block Storage service can be transferred to the Private Image Catalog. This feature is particularly useful for instances that originated from a volume, or simply as a way of exporting one.

Can I import a virtual machine image from VMware?
Yes, you can export your instance from VMware vSphere in VMDK format, and send it directly to your Private Image Catalog to use it.
Can I import a virtual machine image from AWS?
Yes, you can use AWS formats (e.g. AMI, AKI, ARI), and send them directly to your Private Image Catalog to use them.
Can I import a virtual machine image from Azure?
Yes, you can export your instance from Microsoft Azure in VHD format, and send it directly to your Private Image Catalog to use it.
What is the target architecture for cloud images?
Hypervisors are servers with an x86-64 architecture. It is important to choose images that are compatible with this architecture, otherwise they will not work.
What is the maximum size limit for a cloud image?
There is no maximum size in the Private Image Catalog, apart from the 5TB Object Storage limit for objects. The maximum size will mainly depend on the target instance model. For example, you cannot use a 100GB image for an instance model that offers 50GB disk space. Please also note that the smaller the image, the quicker an instance will boot — the transfer time between the catalog and the hypervisor will be reduced.
