where <instance-name> is the name of a Multipass instance.


The size of the instance’s disk.

The disk size can only be increased.

Allowed values

A size no smaller than the current disk size. This size can be specified with a positive integer or decimal number, optionally followed by a unit. Any case variations of the following suffixes are accepted as units:

  • B, to designate one byte.
  • KiB, KB, or K, to designate 1024 bytes.
  • MiB, MB, or M, to designate 1024 x 1024 = 1048576 bytes
  • GiB, GB, or G, to designate 1024 x 1024 x 1024 = 1073741824 bytes

Decimal bytes (e.g. 1.1B) are refused, unless specified with larger units (>= KiB), in which case the amount is floored (e.g. 1.2KiB is interpreted as 1228B, even though 1.2 x 1024 = 1228.8).


multipass set local.handsome-ling.disk=7.5G

Default value

The size of the disk that the instance was launched with.

Just reporting a minor typo on the nav bar. The left navigation bar has two entries for local.<instance-name>.memory, where the first one correctly links to this disk documentation page.
Thank you for this great tool!
