Increasing Disk Capacity

If you find that the capacity of the virtual hard disk of your virtual machine or Container does not fit your needs anymore, you can increase it using the prlctl set --device-set command. For example:

# prlctl set MyVM --device-set hdd0 --size 80G

Note: To virtual machines, additional disk space is added as unallocated. You can use standard means (e.g., the Disk Management tool in Windows-based virtual machines) to allocate added space by creating a new or expanding the existing partition.

When increasing the disk capacity, keep in mind the following:

• You cannot increase the capacity of a virtual disk used by a virtual machine if the virtual machine is running.
• The virtual machine using the virtual disk you want to configure must not have any snapshots. In this case, you should delete all existing snapshots and run the command again. To learn how to delete snapshots of a virtual machine, refer to Deleting Snapshots.
• The capacity of an expanding virtual disk shown from inside the virtual machine or Container and the size the virtual disk occupies on the server's physical disk may differ.
