`multipass info` command
The multipass info
command shows properties of instances and snapshots.
For example, multipass info calm-squirrel
:
Name: calm-squirrel
State: RUNNING
Snapshots: 2
IPv4: 10.218.69.109
Release: Ubuntu 16.04.6 LTS
Image hash: 2461b36d86ac (Ubuntu 22.04 LTS)
CPU(s): 1
Load: 0.49, 0.70, 0.71
Disk usage: 849.4M out of 4.8G
Memory usage: 41.9M out of 992.0M
Mounts: /home/user => Home
UID map: 1000:default
GID map: 1001:default
/home/user/multipass => mp
UID map: 1000:default
GID map: 1001:default
or, in case of a snapshot, multipass info relative-lion.snapshot3
:
Snapshot: snapshot3
Instance: relative-lion
CPU(s): 1
Disk space: 5.0GiB
Memory size: 1.0GiB

Comment: Before restoring snapshot2
To obtain information on all the snapshots of an instance, you can specify the name of the instance and add the --snapshots
option to the command.
With no positional arguments, multipass info
displays information on all the instances. If you add the --snapshots
flag and no positional arguments, the command displays information on all the snapshots of all instances.
The --format
option allows to choose how the output is formatted. The available options are a human-readable table
, or machine-readable formats: json
, yaml
or csv
.
For example, the command multipass info --format yaml calm-squirrel
produces the following output:
errors:

Details available for instances and snapshots
Here you can find a comprehensive list of the details that multipass info
provides for instances and snapshots, respectively.
Instance details
Entry | Description |
---|---|
Name |
Name of the instance that the information pertains to |
State |
Current state of the instance (see also: Instance states) |
Snapshots |
Number of snapshots of the instance |
IPv4 |
A list of IPs through which a machine on the same network as the instance can reach the instance. Adding IP addresses besides the one automatically generated by Multipass is described in How to create an instance with multiple network interfaces. |
Release |
Title of the release of the image installed on this instance |
Image hash |
The SHA-256 hash of the aforementioned image. This can be used to verify the validity of the image. |
CPU(s) |
Number of cores that the instance can use, as defined by the --cpus option of the launch command or as modified by the local.<instance-name>.cpus key of the set command. Depending on the used driver, this value can exceed the number of CPUs on the host machine. |
Load |
A triplet of values describing the average number of processes running on the CPU or in queue waiting for CPU time, sampled over the last 1 minute, 5 minutes and 15 minutes respectively. The values are normalized to the number of CPU cores, so for a machine with N cores, a load average of N indicates that the CPU is utilized at maximum capacity over the respective time interval, while a value below or above N indicates that the CPU is either under-utilized or over-utilized. |
Disk usage |
Amount of disk space used by the instance, as defined by the --disk option of the launch command or as modified by the local.<instance-name>.disk key of the set command. |
Memory usage |
Amount of memory used by the instance, as defined by the --memory option of the launch command or as modified by the local.<instance-name>.memory key of the set command. Depending on the used driver, the total value can exceed the amount of memory available on the host machine, but the used value cannot. |
Mounts |
List of directories on the host machine that are accessible through their respective directories from inside the instance. Each directory mapping has a list of UID and GID mappings, representing how the ownership of their respective host directories is translated the ownership of their respective instance directories. See also: Mount. |
Snapshot details
Entry | Description |
---|---|
Snapshot |
Name of the snapshot that the following details pertain to, as defined by the --name option of the snapshot command or by the local.<instance>.<snapshot>.name key on the set command. |
Instance |
Name of the instance that snapshot belongs too |
CPU(s) |
Number of cores that were assigned to the instance when the snapshot was taken, as defined by the --cpus option of the launch command or as modified by the local.<instance-name>.cpus key of the set command. |
Disk space |
Size of the instances disk when the snapshot was taken, as defined by the --disk option of the launch command or as modified by the local.<instance-name>.disk key of the set command. |
Memory size |
Amount of memory that was assigned to the instance when the snapshot was taken, as defined by the --memory option of the launch command or as modified by the local.<instance-name>.memory key of the set command. |
Mounts |
List of directories on the host machine that were mounted inside the instance at the time that the snapshot was taken. See also: Mount. |
Created |
Timestamp containing the date and time when the snapshot was created |
Parent |
The snapshot that was last in effect when this snapshot was taken, relatively to which the current snapshot records changes |
Children |
A list of snapshots that have this snapshot as a parent |
Comment |
The comment that is associated with the snapshot, as defined by the --comment option of the snapshot command or by the local.<instance>.<snapshot>.comment key on the set command. |
The full multipass help info
output explains the available options:
Usage: multipass info [options] <instance>[.snapshot] [<instance>[.snapshot] ...]
Display information about instances or snapshots
Options:
-h, --help Displays help on commandline options
-v, --verbose Increase logging verbosity. Repeat the 'v' in the short
option for more detail. Maximum verbosity is obtained with
4 (or more) v's, i.e. -vvvv.
--snapshots Display detailed information about the snapshots of
specified instances. This option has no effect on snapshot
arguments. Omit instance/snapshot arguments to obtain
detailed information on all the snapshots of all instances.
--format <format> Output info in the requested format.
Valid formats are: table (default), json, csv and yaml.
Arguments:
instance/snapshot Names of instances or snapshots to display information
about
