Operations on Virtual Machines and Containers 79
 The capacity of an expanding virtual disk shown from inside the virtual machine and the
size the virtual disk occupies on the server's physical disk may differ.
Compacting the Virtual Disk
In Parallels Server Bare Metal, you can decrease the space your virtual machines occupy on the
Parallels server's disk drive by compacting their virtual disks. Compacting virtual disks allows
you to save your server's disk space and host more virtual machines and Containers on the
server.
Note: Plain disk cannot be compacted.
To compact a virtual disk, you can use the prl_disk_tool compact command. For
example, to compact the MyVM-0.hdd disk, you can run this command:
# prl_disk_tool compact --hdd /vz/MyVM.pvm/MyVM-0.hdd/
Operation progress 100 %
To check the space that was freed by compacting the virtual disk, you can use standard Linux
utilities (e.g. the df utility).
