Change-Id: Ieb24b3a0c210291d8c04412e4c263b5e377b5704 Ludovic Courtès 2024-03-06services: virtual-build-machine: Disable substitutes by default....These are useless when offloading yet were causing problems on systems where the default substitute servers are unreachable. * gnu/services/virtualization.scm (%virtual-build-machine-operating-system): Add ‘use-substitutes?’ field to ‘guix-configuration’. Change-Id: I7d5e380a6f2e2d537de43fdb3c550958ed4db255 Ludovic Courtès 2024-02-18services: virtual-build-machine: Add ‘configuration’ action....* gnu/services/virtualization.scm (build-vm-shepherd-services): Add ‘configuration’ action. * doc/guix.texi (Virtualization Services): Document it. Change-Id: I4734e096d744b3cda0d523692498a73c0029e188 Ludovic Courtès 2024-02-18services: virtual-build-machine: Add periodic GC job....* gnu/services/virtualization.scm (%virtual-build-machine-operating-system): Add ‘periodic-gc’ service. Change-Id: Id5bde1ee3f8e1e549e231375e776d3201ec9e0b5 Ludovic Courtès 2024-02-18services: virtual-build-machine: Use a non-volatile root file system....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 Ludovic Courtès 2024-02-18services: virtual-build-machine: Do not offload when service is stopped....* gnu/services/virtualization.scm (check-vm-availability): Check the value of ‘live-service-running’. Change-Id: Iba858ea0fa417d9276e026b72b4b78791932482e Ludovic Courtès 2024-02-12services: virtual-build-machine: Use a larger partition by default....So far the partition had too little free space. * gnu/services/virtualization.scm (%default-virtual-build-machine-image-size): New variable. (virtual-build-machine-default-image): Define ‘partitions’ field. Change-Id: Iffe0f316eecad8754d29f8c811cdc4836a818a3f Ludovic Courtès 2024-02-12services: virtual-build-machine: Add base file systems to default OS....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 Ludovic Courtès 2024-02-10services: Add ‘virtual-build-machine’ service....* gnu/services/virtualization.scm (<virtual-build-machine>): New record type. (%build-vm-ssh-port, %build-vm-secrets-port, %x86-64-intel-cpu-models): New variables. (qemu-cpu-model-for-date, virtual-build-machine-ssh-port) (virtual-build-machine-secrets-port): New procedures. (%minimal-vm-syslog-config, %virtual-build-machine-operating-system): New variables. (virtual-build-machine-default-image): (virtual-build-machine-account-name) (virtual-build-machine-accounts) (build-vm-shepherd-services) (initialize-build-vm-substitutes) (build-vm-activation) (virtual-build-machine-offloading-ssh-key) (virtual-build-machine-activation) (virtual-build-machine-secret-root) (check-vm-availability) (build-vm-guix-extension): New procedures. (initialize-hurd-vm-substitutes): Remove. (hurd-vm-activation): Rewrite in terms of ‘build-vm-activation’. * gnu/system/vm.scm (linux-image-startup-command): New procedure. (operating-system-for-image): Export. * gnu/tests/virtualization.scm (run-command-over-ssh): New procedure, extracted from… (run-childhurd-test): … here. [test]: Adjust accordingly. (%build-vm-os): New variable. (run-build-vm-test): New procedure. (%test-build-vm): New variable. * doc/guix.texi (Virtualization Services)[Virtual Build Machines]: New section. (Build Environment Setup): Add cross-reference. Change-Id: I0a47652a583062314020325aedb654f11cb2499c Ludovic Courtès 2024-02-10services: secret-service: Make the endpoint configurable....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 Ludovic Courtès 2023-10-05services: hurd-vm: Leave root password uninitialized when offloading....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. Ludovic Courtès 2023-10-01services: hurd-vm: Implement zero-configuration offloading....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. Ludovic Courtès 2023-10-01services: hurd-vm: Disable password-based authentication for root....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. Ludovic Courtès 2023-10-01services: hurd-vm: ‘image’ field has to be an <image> record....* 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. Ludovic Courtès 2023-10-01services: childhurd: Authorize the childhurd’s key on the host....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. Ludovic Courtès 2023-10-01services: hurd-vm: Use the default SSH port number....* 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. Ludovic Courtès 2023-09-18services: hurd-vm: Use ‘qemu-system-x86_64’....Fixes <https://issues.guix.gnu.org/66053>. * gnu/services/virtualization.scm (hurd-vm-shepherd-service)[vm-command]: Use ‘qemu-system-x86_64’.
