All virtual machine-related file I/O is performed under this user. Configuring datastore principal user will result in all virtual machine files (configuration, disk, and so on) being checked for proper access. If necessary, ownership and permissions are modified. Note that in some environments, file ownership and permissions modification may not be possible. For example, virtual machine files stored on NFS cannot be modified for ownership and permissions if root squashing is enabled. Ownership and permissions for these files must be manually changed by a system administrator. In general, if server process does not have rights to change ownership and file permissions of virtual machine files, they must be modified manually. If a virtual machine files are not read/writeable by this user, virtual machine related operations such as power on/off, configuration, and so on will fail. This operation must be performed while in maintenance mode and requires host reboot.
