1. Select when creating a virtual machine

2. Enter the operating system to see that the disk space has been increased to the corresponding size.

3. repartitioning

The device presents a logical sector size is smaller than

The physical sector size. Aligning to a physical sector (or optimal

I/O) size boundary is recommended, or performance could be impacted.

Welcome to Fdisk (Util-linux 2.23.2).

Changes'll remain in memory only, until the decide to write them.

Be careful before using the Write command.
