2024-03-06services: virtual-build-machine: Disable substitutes by default.Ludovic Courtès

2024-02-18services: virtual-build-machine: Use a non-volatile root file system.Ludovic Courtès
This is a followup to e0ade40c2b7f39dc109ef03d43241033e14c4d4a, which didn’t have the desired effect. * gnu/services/virtualization.scm (virtual-build-machine-default-image): Add ‘volatile-root?’ field. Change-Id: I1a622f22cdd0f8f83860a6eb4a852518db3b46b7

2024-02-12services: virtual-build-machine: Use a larger partition by default.Ludovic Courtès

2024-02-12services: virtual-build-machine: Add base file systems to default OS.Ludovic Courtès
This provides /dev/pts and other things that are important for builds (for example, Python 2.x has ‘openpty’ unit tests that can only succeed when /dev/pts is available.) * gnu/services/virtualization.scm (%virtual-build-machine-operating-system) [file-systems]: Add %BASE-FILE-SYSTEMS. Change-Id: I7d12a4cb491e957bf55e6c5f9dd09c013473ca42

2024-02-10services: secret-service: Make the endpoint configurable.Ludovic Courtès
Until now, the secret service had a hard-coded TCP endpoint on port 1004. This change lets users specify arbitrary socket addresses. * gnu/build/secret-service.scm (socket-address->string): New procedure, taken from Shepherd. (secret-service-send-secrets): Replace ‘port’ by ‘address’ and adjust accordingly. (secret-service-receive-secrets): Likewise. * gnu/services/virtualization.scm (secret-service-shepherd-services): Likewise. (secret-service-operating-system): Add optional ‘address’ parameter and honor it. Adjust ‘start’ method accordingly. Change-Id: I87a9514f1c170dca756ce76083d7182c6ebf6578
2023-10-05services: hurd-vm: Leave root password uninitialized when offloading.Ludovic Courtès
Starting with 953c65ffdd43c02c934518fb7a1c68542584b223, offloading to the Hurd VM would be enabled by default. However, ‘root’ had an empty password so any user on the host could connect to the VM over VNC, log in as root, and potentially populate the host’s store from there. This change fixes that. * gnu/services/virtualization.scm (operating-system-with-locked-root-account): New procedure. (hurd-vm-disk-image)[transform]: Add ‘operating-system-with-locked-root-account’ when offloading.
2023-10-01services: hurd-vm: Implement zero-configuration offloading.Ludovic Courtès
This allows for zero-configuration offloading to a childhurd. * gnu/services/virtualization.scm (operating-system-with-offloading-account): New procedure. (<hurd-vm-configuration>)[offloading?]: New field. (hurd-vm-disk-image): Define ‘transform’ and use it. (hurd-vm-activation): Generate SSH key for user ‘offloading’ and add authorize it via /etc/childhurd/etc/ssh/authorized_keys.d. (hurd-vm-configuration-offloading-ssh-key) (hurd-vm-guix-extension): New procedures. (hurd-vm-service-type): Add GUIX-SERVICE-TYPE extension. * gnu/tests/virtualization.scm (run-childhurd-test)[import-module?]: New procedure. [os]: Add (gnu build install) and its closure to #:import-modules. [test]: Add “copy-on-write store” and “offloading” tests. * doc/guix.texi (Virtualization Services): Document it.
2023-10-01services: hurd-vm: Disable password-based authentication for root.Ludovic Courtès
With offloading to a childhurd is enabled, allowing password-less root login in the childhurd to anyone amounts to providing write access to the host’s store to anyone. Thus, disable password-based root logins in the childhurd. * gnu/services/virtualization.scm (%hurd-vm-operating-system): Change ‘permit-root-login’ to 'prohibit-password. * gnu/tests/virtualization.scm (%childhurd-os): Provide a custom ‘os’ field for ‘hurd-vm-configuration’. * doc/guix.texi (Virtualization Services): Remove mention of password-less root login.
2023-10-01services: hurd-vm: ‘image’ field has to be an <image> record.Ludovic Courtès
* gnu/services/virtualization.scm (<hurd-vm-configuration>)[image]: Document as being an <image> record. (hurd-vm-disk-image): Remove call to ‘system-image’. (hurd-vm-shepherd-service): Add call to ‘system-image’. * gnu/tests/virtualization.scm (hurd-vm-disk-image-raw): Remove call to ‘system-image’. * doc/guix.texi (Virtualization Services): Adjust accordingly.
2023-10-01services: childhurd: Authorize the childhurd’s key on the host.Ludovic Courtès
This partly automates setting up a childhurd for offloading purposes. * gnu/services/virtualization.scm (authorize-guest-substitutes-on-host): New procedure. (hurd-vm-activation): Use it.
2023-10-01services: hurd-vm: Use the default SSH port number.Ludovic Courtès
* gnu/services/virtualization.scm (%hurd-vm-operating-system): Remove ‘port-number’ from ‘openssh-configuration’. (hurd-vm-net-options): Change 2222 to 22 in port forwarding.
2023-09-18services: hurd-vm: Use ‘qemu-system-x86_64’.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/66053>. * gnu/services/virtualization.scm (hurd-vm-shepherd-service)[vm-command]: Use ‘qemu-system-x86_64’.
2023-07-13services: childhurd: Bump default qemu memory to 2048MB.Janneke Nieuwenhuizen
When booting with pci-arbiter and rumpdisk and using 1024MB of memory for qemu, booting hangs, or seems to hang, at the end of the rumpdisk boot messages. At least 1200MB is required, currently. * gnu/services/virtualization.scm (<hurd-vm-configuration>)[memory-size]: Bump to 2048. * gnu/system/examples/bare-hurd.tmpl: Suggest using 2048 here too. Update example `guix system image' and "qemu" command lines too. Signed-off-by: Josselin Poiret <dev@jpoiret.xyz>

2022-03-10services: secret-service: Do not generate SSH and Guix key pairs.Ludovic Courtès
The justification about the order of activation snippets given in the comment had been obsolete since 39e3b4b7cee175a3c1f37329744c582528d55f5d. Lately, running the activation snippets for "ssh-keygen -A" and "guix archive --generate-key" would take a little bit too long, thereby preventing the childhurd from starting on time. * gnu/services/virtualization.scm (secret-service-operating-system): Clear 'generate-host-keys?' and 'generate-substitute-key?'.
2022-02-18services: qemu-guest-agent: Fix implementation.Ludovic Courtès
Previously, by accessing the raw <qemu-guest-agent-configuration> fields, 'qemu' would match the first field, which is the '%location' field, not the 'qemu' field. It would seem this bug has always been present since the addition of the 'location' field in d132d9f96ba34bca58b18e293e03b393054fd962 predates the addition of 'qemu-guest-agent-service-type' in f634a0baab85454a6feac25e29905f564b276c9e. Fixes <https://issues.guix.gnu.org/54041>. Reported by Ricardo Wurmus <rekado@elephly.net>. * gnu/services/virtualization.scm (qemu-guest-agent-shepherd-service): Use accessors for <qemu-guest-agent-configuration>.

2021-07-10services: qemu-binfmt: Preserve argv[0] by default.Ludovic Courtès
Previously, argv[0] would be replaced by the absolute file name of the executable. This could cause discrepancies, for example in the Coreutils test suite: <https://issues.guix.gnu.org/49485>. * gnu/services/virtualization.scm (<qemu-platform>)[flags]: Default to "FP".
2021-03-15services/qemu-binfmt: Use the F flag and the static output of QEMU.Maxim Cournoyer
Fixes <https://issues.guix.gnu.org/36117>. Before this change, the 'binfmt_misc' entries registered for QEMU would not be usable in container contexts outside of guix-daemon (without manually bind mounting file names). For example: $ docker run --rm arm32v7/debian true standard_init_linux.go:207: exec user process caused "no such file or directory" After this change, any container can make use of the QEMU binfmt_misc registrations, as their corresponding QEMU static binaries are fully pre-loaded by the kernel. * gnu/services/virtualization.scm (<qemu-platform>): Define using 'define-record-type*'. [flags]: New field, which defaults to "F" (fix binary).
