Multipass Changelog

What's new in Multipass 1.14.0 RC 1

May 7, 2024
  • The new graphical user interface (GUI) should make it much easier and intuitive to manage your Multipass virtual machine instances. This is what we call a minimal viable product and as time goes on, we will be adding more functionality and tweaking the interface. You can launch the new GUI by looking for "Multipass" in the ways you normally launch applications on your host platform. Please try it out and provide feedback.
  • The ability to add an external bridged network to an existing instance. Much like what multipass launch --bridged does, but for an already existing instance. In order to do this, you must:
  • Set a default bridge via multipass set local.bridged-network
  • Set the instance to use the bridged network via multipass set local..bridged=true
  • Classic mounts are more secure now.
  • More highlights:
  • The Snap package has been greatly optimized. It is ~48% smaller in size (122MB -> 64MB).
  • The date and time inside an instance should not skew when resuming from suspend. (#982)
  • Along with aforementioned GUI, the icon set has been updated including light and dark mode icons on macOS.
  • Switched to using vcpkg for building the grpc and POCO library dependencies.

New in Multipass 1.13.1 (Feb 13, 2024)

  • This is a bug fix release addressing the following issues:
  • [snapshots] Rollback of failed restore wrongly applies last snapshot #3362
  • [regression] multipass aliases command throws segmentation fault #3383
  • Images used for snapcraft do not report pollinate data #3390
  • [regression] Unhandled exception when converting qcow2 images for snapshot support #3399
  • On macOS only:
  • Instances won't start on Apple M3 silicon #3308

  • This is a bug fix release addressing the following issues:
  • [snapshots] Rollback of failed restore wrongly applies last snapshot #3362
  • [regression] multipass aliases command throws segmentation fault #3383
  • Images used for snapcraft do not report pollinate data #3390
  • [regression] cannot connect to the multipass socket on Intel Mac #3399
  • On macOS only:
  • Instances won't start on Apple M3 silicon #3308

New in Multipass 1.13.0 (Feb 2, 2024)

  • Introducing Snapshots:
  • This release includes the much sought after support for snapshots of instances! With this, you will be able to create an instance, configure it as you see fit, and then take a snapshot of it so you don't have to start from scratch in case something goes wrong with your instance and need to start over.
  • Other significant changes:
  • Multipass has moved to using Qt6 (version 6.2.4 to be exact). This fixes a number of bugs in Qt itself and also allows for PAC files for proxy support.
  • Rewrite of some parts of the cross platform SFTP server used for classic mounts to use std::filesystem instead of QFile. This avoids some bugs in Qt along with using more of the stdlib when we can.
  • Fetching of remote image information is more performant and will not block the client as before.

  • is enough to migrate the Hyperkit instance. Also, please follow the instructions given at the multipass client command line.

New in Multipass 1.11.1 (Feb 7, 2023)

  • [regression, virtualbox] Daemon removes mounts on startup & fails to start instance (#2904)

New in Multipass 1.11.0 (Feb 1, 2023)

  • Native mounts that are more performant are now supported on some platforms/drivers. This is still considered experimental. The following describes which platform and driver combinations support this: The qemu driver on both Linux and macOS (both Intel and M1/M2). The hyperv driver on Windows.
  • Note: On Windows, due to having to use SMB, your user's password is required every time a mount is necessary, including when starting an instance that already has a native mount defined. We are working on a way to make this better.
  • How to define a native mount: When issuing the multipass mount command, pass the --type native option to the command line and Multipass will use the native mount if you are using a supported platform and driver combination. For example: $ multipass mount --type native ~/Downloads foo:Downloads
  • multipass transfer now allows transferring directories recursively using the -r/--recursiveoption and allows making any missing parent directories in the instance using the -p/--parents option.
  • Instances now boot using UEFI allowing Multipass to support launching Ubuntu Core 20 and Core 22.
  • Blueprints now allow command aliases to be defined along with the ability to create a workspace for host/instance integration.
  • Notable bug fixes:
  • [qemu] daemon starting instance twice if triggered on startup (#2520)
  • sshfs_server not cleanly shut down when stopping an instance (#1132)
  • sshfs_server gets in tight loop if host mount directory is missing on instance start (#1677)
  • [gui] not reacting to primary instance being purged (#1241)
  • Broken process substitution for multipass launch command (#1589)
  • [lxd] Multipass not reacting correctly with internally shut down instances (#2672)
  • [mounts] Repeated id/gid mappings (#2665)
  • make multipass list --format csv|json|yaml output consistent (#2464)
  • List cpu count in multipass info (#1804)
  • multipass launch should allow --memory as a synonym of --mem (#2490)

  • Note: On Windows, due to having to use SMB, your user's password is required every time a mount is necessary including when starting an instance that already has a native mount defined. We are working on a way to make this better.
  • How to define a native mount:
  • When issuing the multipass mount command, pass the -t native option to the command line and Multipass will use the native mount if you are using a supported platform and driver combination. For example:
  • $ multipass mount -t native ~/Downloads foo:Downloads
  • multipass transfer now allows transferring directories recursively using the -r/--recursiveoption and allows making any missing parent directories in the instance using the -p/--parents option.

  • [regression] New exec working directory mapping does not take sudo into account (#2663)

New in Multipass 1.10.0 (Jul 17, 2022)

  • Modifying instances is now supported. You can modify the number of cores, memory, and disk space allocated to an instance. Note that instances can only be modified when they are not running and disk space can only be increased. See https://multipass.run/docs/modify-an-instance#heading--set-the-cpu-ram-or-disk-of-an-instance for more information.
  • On Windows, Multipass now supports creating generation 2 virtual machines in Hyper-V along with disabling dynamic memory. These apply only to new instances launched and not existing instances.
  • Specifying mounts at launch time is now possible via multipass launch --mount.
  • It's now possible to use a URL when using the --cloud-init option in launch.
  • There are few enhancements to the multipass exec and multipass alias commands. See https://multipass.run/docs/exec-command and https://multipass.run/docs/alias-command respectively for details.
  • More highlights:
  • Launching an instance using the lxd driver will now use the general cloud image instead of the KVM image. This is due to the KVM kernel in the image having unfixed bugs. (#2491)
  • multipass transfer now handles a directory being a target. (#1165)
  • The Multipass icon is now shown in the "Windows Apps & Features" Multipass entry. (#2595)
  • It's now possible to unalias all defined aliases at once. (#2298)
  • Notable bug fixes:
  • LXD VMs constructed with wrong storage pool on daemon startup (#2591)
  • [lxd] long startup delay due to image refresh (#2516)
  • [macos/qemu] Multiple qemu processes running for the same instance (#2592)

New in Multipass 1.9.0 (May 4, 2022)

  • There are some significant additions to this release:
  • It is now possible to authenticate the client with the Multipass service. This write up explains how some of this works. This basically makes it possible to use the multipass client as a non admin user on Linux and macOS and closes the security gap on Windows.
  • Multipass on Apple M1 by default and Intel hosts using the qemu driver now support adding additional networks (via --network on launch). Additionally, suspending instances on the M1 now works (via multipass suspend )!

  • There's a number of significant additions in this one:
  • multipass launch , where workflows are defined in canonical/multipass-workflows
  • On top of the official Ubuntu images we now offer the ability to launch complex workloads defined via simple YAML in the above repository. We want project communities to contribute and maintain the workflows they care about. Come along! #2040
