What Do I Do If the System Disk Size in a VHD Image File Exceeds the One I Have Specified on the Management Console When I Use This File to Register a Private Image?

The possible causes may be:
  1. You have specified a small value.

    Check the system disk size in the VHD image file. Specify a value no less than this size when you use the VHD image file to register an image.

  2. The actual size of the VHD image file is larger than its virtual size, if this VHD image file is generated using qemu-img or a similar tool. For details, see https://bugs.launchpad.net/qemu/+bug/1490611.

    Run the following command to check the VHD image file information:

    [xxxx@xxxxx test]$ qemu-img info 2g.vhd
image: 2g.vhd
file format: vpc
virtual size: 2.0G (2147991552 bytes)
disk size: 8.0K
cluster_size: 2097152

    The virtual size is converted from the actual size (unit: byte) to an integer in GB. As a result, the actual file size 2147991552 bytes (2.0004 GB) is larger than the virtual size 2 GB. Therefore, you need to specify a value larger than the actual size 2.0004 GB. (The system disk size value on the management can only be an integer, so you only need to enter a value larger than 2.)
