How Do I Import an OVF or OVA File to the Cloud Platform?

Scenarios

Open Virtualization Appliance (OVA) is a single file archive (with the .ova extension) of all of the files comprising an Open Virtualization Format (OVF) package. OVF is a package of the files required for defining and deploying VMs. An OVF package generally includes .ovf, .mf, and .vmdk files.

• An .ovf file is an XML descriptor that defines the metadata of a VM, such as the name and hardware requirements, and contains information about other files in the OVF package.
• An .mf file contains the SHA hash codes of all the files in the package and is used to prevent the image file from being tampered with.
• A .vmdk file is a virtual disk file that is used to create a disk image. An OVF package may contain multiple .vmdk files.

This section describes how to import OVF and OVA files to the cloud platform.

Procedure

Manually extract VMDK files from an OVF or OVA template and upload them to an OBS bucket. Then, you can select one of them from the bucket when you use an external file to create a system or data disk image.

The following assumes that the OVF or OVA template contains only one VMDK file. If there are multiple VMDK files (for example, there are three VMDK files, one used as a system disk image file and the others as data disk image files), upload them to an OBS bucket and register them as a system disk image and data disk images, respectively.

• The source VM runs Linux.
  • If you choose to export an OVF template, upload the VMDK file generated in the folder to the cloud platform.
  • If you choose to export an OVA template and name it MyVm, perform the following operations:
    1. Run the following command to check the OVA file:

       file MyVm.ova

       The command output is as follows:

       MyVm.ova: POSIX tar archive (GNU)

       MyVm.ova contains the following two files:

       $tar tf MyVm.ova
       MyVm.ovf
       MyVm.vmdk

    2. Run the following command to decompress MyVm.ova:

       tar xvf MyVm.ova

       The extracted folder contains the following files:

       MyVm.ovf
       MyVm.vmdk

       The .vmdk image file can be uploaded to the cloud platform.

       

       You can import an image file in the VHD, VMDK, QCOW2, RAW, VHDX, QCOW, VDI, QED, ZVHD, or ZVHD2 format to create a private image.
