-# Bridging the gaps with the Tart Guest Agent
-
-We're introducing a new improvement for the Tart usability experience: a [Tart Guest Agent](https://github.com/cirruslabs/tart-guest-agent).
-
-This agent provides automatic disk resizing, seamless clipboard sharing for macOS guests (a [long-awaited](https://github.com/cirruslabs/tart/issues/14) feature), and the ability to run commands, without SSH and networking, using the new `tart exec` command.
-
-As of recently, we include this agent in all non-vanilla Cirrus Labs images, so you likely won't need to do anything to benefit from these usability improvements.
-
-Read on to learn why we chose to implement the agent from scratch in Golang, and which features we plan to add next.
-
-<!-- more -->
-
-## Existing solutions
-
-Tart uses the Virtualization.Framework, and the latter implemented a SPICE client some time ago, however, one piece was missing: the agent that runs inside the guest.
-
-The original [SPICE `vdagent` implementation](https://gitlab.freedesktop.org/spice/linux/vd_agent) only supports Linux. While [a fork](https://github.com/utmapp/vd_agent) from the UTM project adds macOS support, the long-term viability of maintaining this fork without upstreaming changes is uncertain.
-
-Moreover, if we were to add some extra functionality (as we did), there would be more than one agent binary to ship and install, which complicates maintenance and makes it harder to explain to users why we need a bunch of agent binaries.
-
-In the end, we decided to go with our own solution, one that would easily accomodate future ideas.
-
-## Rolling our own agent
-
-After carefully inspecting the [`vdagent` protocol](https://www.spice-space.org/agent-protocol.html) we've realized that the clipboard sharing is actually a small subset of the whole protocol, making it relatively simple to implement.
-
-Thanks to Golang, we were able to implement the protocol much faster than we could have with a lower-level language like C (with all due respect), which requires manual memory management and complex event loops.
-
-As for the command execution via `tart exec`, we've decided to go with gRPC with a rather simple protocol:
-
-![An visualization of gRPC protocol used by the Tart Guest Agent](../images/tart-guest-agent-grpc-protocol.png)
-
-For each `tart exec` invocation a new gRPC `Exec` bidirectional stream is established with the agent running inside a VM. After the gRPC stream is established, `tart exec` sends a command to execute to the guest and streams the I/O. Once the command terminates, `tart exec` collects the process exit code and quits with exactly that exit code.
-
-Using gRPC simplifies `tart exec` implementation because of code generation and forms a nice bridge between the host and the guest which allows us to easily expand the protocol later down the road when we decide to introduce new features.
-
-Thanks to [gRPC Swift](https://github.com/grpc/grpc-swift), which is built on top of [SwiftNIO](https://github.com/apple/swift-nio), we get [`async/await`](https://docs.swift.org/swift-book/documentation/the-swift-programming-language/concurrency/) support for free, further simplifying the `tart exec` logic.
-
-As for the Tart Guest Agent, the final result is a Golang binary that [can be customized](https://github.com/cirruslabs/tart-guest-agent?tab=readme-ov-file#guest-agent-for-tart-vms) depending on the execution context:
-
-* launchd global daemon — runs as a privileged user (`root`), has no clipboard access
-    * `--resize-disk` — resizes the disk when there's a free space at the end of a disk (assuming that one previously ran `tart set --disk-size`)
-* launchd global agent — runs as a normal user (`admin`), has clipboard access
-    * `--run-vdagent` — clipboard sharing
-    * `--run-rpc` — `tart exec` and new functionality in the future
-
-We’ve also introduced `--run-daemon` (which implies `--resize-disk`) and `--run-agent` (which implies both `--run-vdagent` and `--run-rpc`) to help run the most appropriate functionality based on the given context.
-
-## Future plans
-
-First, we'd like to thank our paid clients, without whom this feature wouldn't have been possible.
-
-[Become one now](../../licensing.md) and enjoy higher allowances for Tart VMs and Orchard workers—while helping ensure that our roadmap aligns with your company's needs.
-
-In the near future we plan to implement:
-
-* Linux support — to provide seamless experience for Linux guests too
-* a new `tart ip` resolver — to provide a more robust IP retrieval facility for Linux guests, which often struggle to populate the host's ARP table with their network activity
-* `tart cp` command — to copy files from/to guest VMs
-
-Stay tuned, and feel free to send us feedback on [GitHub](https://github.com/cirruslabs/tart) and [Twitter](https://x.com/cirrus_labs)!

-# Press Release: Cirrus Labs Successfully Enforces Its Fair Source License

-<!-- more -->
-
-Cirrus Labs makes its Tart Virtualization Toolset, a leading virtualization toolset to build, run and manage macOS and Linux virtual machines (VMs) on Apple Silicon,
-freely available on GitHub under the Fair Source License, a source-available license. Tart is used by tens of thousands of engineers at no charge within its generous free‑use limits.
-Many large enterprises that need to exceed those limits support continued development through paid licenses. Cirrus Labs also uses Tart to power [Cirrus Runners](https://cirrus-runners.app/)
-— a drop‑in replacement for macOS and Linux runners for GitHub Actions — offered at a fixed monthly price for unlimited usage.
-
-Cirrus Labs discovered that, **despite a prior licensing request that was declined due to a conflict of interest**, another company used Tart in a manner that exceeded the license’s free‑use limits,
-in order to create a competing product.
-
-After several months of negotiations, the matter was settled and a settlement payment to Cirrus Labs was agreed upon.
-
-!!! quote "Comment by Fedor Korotkov, CEO of Cirrus Labs"
-    
-    As a company we embrace healthy competition that ultimately benefits the end user. Most of our users have no trouble complying with our license,
-    and even when they need something more than our free use limits, we can almost always grant them a license that fits their needs. **This was an exceptional case.**
-    We are pleased to have reached this settlement, which validates our source-available licensing strategy and reinforces our commitment to protecting our company and serving our community.

-## Headless machines
-
-Starting from macOS 15 (Sequoia), there's an undocumented requirement from [Virtualization.Framework](https://developer.apple.com/documentation/virtualization) (which Tart uses) to have an unlocked `login.keychain` available at the times when running a VM.
-
-Without an existing and unlocked `login.keychain`, the VM won't start with errors like:
-
-* `SecKeyCreateRandomKey_ios failed`
-* `Failed to generate keypair`
-* `Interaction is not allowed with the Security Server`
-
-Below you'll find a couple of workarounds for this behavior.
-
-### Log in via GUI at least once
-
-Connect to the headless machine via [Screen Sharing](https://support.apple.com/guide/mac-help/share-the-screen-of-another-mac-mh14066/mac) and log in to a Mac user account. If you haven't done already, you can enable Screen Sharing [via the terminal](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/connect-to-mac-instance.html#mac-instance-vnc).
-
-Logging in graphically will automatically create the `login.keychain`. Afterward, you have two options:
-
-* configure [automatic log in to a Mac user account](https://support.apple.com/en-us/102316)
-    * this will maintain a running user session (GUI) even after the machine reboots
-    * moreover, you can still lock the screen (either manually [or automatically](https://support.apple.com/guide/mac-help/change-lock-screen-settings-on-mac-mh11784/mac)), however, the security benefit of this is questionable
-* use `security unlock-keychain login.keychain` to unlock the login keychain via the terminal
-    * this command also supports the `-p` command-line argument, which allows you to supply a password and unlock non-interactively
-
-### Create and unlock the login keychain via the terminal
-
-Compared to the previous approach, this one is fully automated, but might stop working at some point in the future:
-
-```shell
-security create-keychain -p '' login.keychain
-security unlock-keychain -p '' login.keychain
-security login-keychain -s login.keychain
-```
-
-Note that this will create a `login.keychain` with an empty password. Consider supplying a different value to `-p` or omitting the `-p` to enter the password interactively.

-## Avoiding the "Local Network" permission pop-up
-
-Starting from macOS 15 (Sequoia), a GUI "Local Network" permission pop-up might appear when Tart is used by another tool that needs to connect to a VM over a private IPv4 network, for example [Packer](https://developer.hashicorp.com/packer/integrations/cirruslabs/tart/latest/components/builder/tart).

-If you need a non-interactive workaround, you can configure the [local network privacy preferences](https://developer.apple.com/documentation/technotes/tn3179-understanding-local-network-privacy#macOS-considerations) on the host so that all [RFC 1918](https://datatracker.ietf.org/doc/html/rfc1918#section-3) address ranges that Tart VMs commonly use are excluded from the prompt:

-## Disk resizing
-
-Disk resizing works on most cloud-ready Linux distributions out-of-the box (e.g. Ubuntu Cloud Images have the `cloud-initramfs-growroot` package installed that runs on boot) and on the rest of the distributions by running the `growpart` or `resize2fs` commands.
-
-For macOS, however, things are a bit more complicated, and you generally have two options: automated and manual resizing.
-
-For the automated option, you can use [Packer](https://www.packer.io/) with the [Packer builder for Tart VMs](https://developer.hashicorp.com/packer/integrations/cirruslabs/tart/latest/components/builder/tart). The latter has two has configuration directives related to the disk resizing behavior:
-
-* [`disk_size_gb`](https://developer.hashicorp.com/packer/integrations/cirruslabs/tart/latest/components/builder/tart#configuration-reference) — controls the target disk size in gigabytes
-* [`recovery_partition`](https://developer.hashicorp.com/packer/integrations/cirruslabs/tart/latest/components/builder/tart#configuration-reference) — controls what to do with the recovery partition when resizing the disk
-    * you can either keep, delete or relocate it to the end of the disk
-
-For the manual approach, you have to remove the recovery partition first, repair the disk and the resize the APFS container.
-
-To do this, first we'll need to identify the primary disk and the APFS containers by running the command below from within a VM:
-
-```shell
-diskutil list physical
-```
-
-For example, the output might look like this:
-
-```plain
-/dev/disk0 (internal, physical):
-   #:                       TYPE NAME                    SIZE       IDENTIFIER
-   0:      GUID_partition_scheme                        *100.0 GB   disk0
-   1:             Apple_APFS_ISC Container disk1         524.3 MB   disk0s1
-   2:                 Apple_APFS Container disk3         44.1 GB    disk0s2
-   3:        Apple_APFS_Recovery Container disk2         5.4 GB     disk0s3
-                    (free space)                         50.0 GB    -
-```
-
-In the output, you'll normally see:
-
-* a single physical disk (`disk0`)
-* APFS container with the system partition which we're going to resize (`disk0s2`)
-* APFS container with the recovery partition which we're going to delete (`disk0s3`)
-* `(free space)` which we'll put to use
-
-To proceed, boot the VM in recovery mode using `tart run --recovery` and choose the "Options" item:
-
-![](assets/images/faq/tart-run-recovery-options.png){width="640" .center}
-
-When the recovery OS boots, open the Terminal app:
-
-![](assets/images/faq/tart-run-recovery-terminal.png){width="720" .center}
-
-In Terminal app, invoke the command below to remove the recovery partition:
-
-```shell
-diskutil eraseVolume free free disk0s3
-```
-
-Now, repair the disk:
-
-```shell
-yes | diskutil repairDisk disk0
-```
-
-Finally, resize the system APFS container to take all the remaining space:
-
-```shell
-diskutil apfs resizeContainer disk0s2 0
-```
-
-Now, you can shut down and `tart run` as you'd normally do.
