Uploading an image file using the web console

Use the web console to upload an image file to a new persistent volume claim (PVC). You can later use this PVC to attach the image to new virtual machines.

Prerequisites

  • You must have one of the following:

    • A raw virtual machine image file in either ISO or IMG format.

    • A virtual machine image file in QCOW2 format.

  • For best results, compress your image file according to the following guidelines before you upload it:

    • Compress a raw image file by using xz or gzip.

      Using a compressed raw image file results in the most efficient upload.

    • Compress a QCOW2 image file by using the method that is recommended for your client:

      • If you use a Linux client, sparsify the QCOW2 file by using the virt-sparsify tool.

      • If you use a Windows client, compress the QCOW2 file by using xz or gzip.

Procedure

  1. From the side menu of the web console, click Storage → Persistent Volume Claims.

  2. Click the Create Persistent Volume Claim drop-down list to expand it.

  3. Click With Data Upload Form to open the Upload Data to Persistent Volume Claim page.

  4. Click Browse to open the file manager and select the image that you want to upload, or drag the file into the Drag a file here or browse to upload field.

  5. Optional: Set this image as the default image for a specific operating system.

    1. Select the Attach this data to a virtual machine operating system check box.

    2. Select an operating system from the list.

  6. The Persistent Volume Claim Name field is automatically filled with a unique name and cannot be edited. Take note of the name assigned to the PVC so that you can identify it later, if necessary.

  7. Select a storage class from the Storage Class list.

  8. In the Size field, enter the size value for the PVC. Select the corresponding unit of measurement from the drop-down list.

    The PVC size must be larger than the size of the uncompressed virtual disk.

  9. Select an Access Mode that matches the storage class that you selected.

  10. Click Upload.
