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). (%i386, %i486, %alpha, %arm, %armeb, %sparc, %sparc32plus, %ppc, %ppc64) (%ppc64le, %m68k, %mips, %mipsel, %mipsn32, %mipsn32el, %mips64, %mips64el) (%riscv32, %riscv64, %sh4, %sh4eb, %s390x, %aarch64, %hppa): Adjust. (qemu-binfmt-guix-chroot): Remove variable. (qemu-binfmt-service-type): Remove the qemu-binfmt-guix-chroot extension. * gnu/services/qemu-binfmt (qemu-platform->binfmt): Use the static output of QEMU. * doc/contributing.texi (Submitting Patches): Update doc. * doc/guix.texi (Virtualization Services): Update doc.
2021-01-16services: qemu-binfmt: 'guix-support?' defaults to #t.Stefan
* gnu/services/virtualization.scm (qemu-binfmt-service-type)[guix-support?]: Change the default from #f to #t. * doc/guix.texi (Transparent Emulation with QEMU): Change the default of ‘guix-support?’ from #f to #t. Describe the implication of setting it to #f. Co-authored-by: Ludovic Courtès <ludo@gnu.org>
2021-01-14services: hurd-vm: Respect hurd-vm-configuration's disk-size.Jan (janneke) Nieuwenhuizen
This is a follow-up to commit 859b362f81598830d7ff276b96a8724aee3c4db7. * gnu/services/virtualization.scm (hurd-vm-disk-image): Use diks-size from config to set image's size.
2020-12-07services: hurd-vm: Avoid circular dependency with (gnu system images hurd).Ludovic Courtès
* gnu/services/virtualization.scm (hurd-vm-disk-image): Use 'lookup-image-type-by-name' instead of referring to 'hurd-disk-image' from (gnu system images hurd).
2020-10-25services: guix: Make /etc/guix/acl really declarative by default.Ludovic Courtès
Fixes <https://bugs.gnu.org/39819>. Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com>. * gnu/services/base.scm (substitute-key-authorization): Symlink DEFAULT-ACL to /etc/guix/acl unconditionally. Add code to optionally back up /etc/guix/acl if it was possibly modified by hand. * doc/guix.texi (Base Services): Clarify the effect of setting 'authorize-keys?' to true. Mention the backup. Give an example showing how to authorize substitutes from another server.

* gnu/services/virtualization.scm (%hurd-vm-operating-system)[packages]: New field.
2020-09-30services: hurd-vm: Add childhurd user to kvm group.Jan (janneke) Nieuwenhuizen

* gnu/services/virtualization.scm (hurd-vm-disk-image): Use 'compressed-qcow2 format.
2020-09-29services: secret-service: Add initial client/server handshake.Ludovic Courtès
This allows the client running on the host to know when it's actually connect to the server running in the guest. Failing that, the client would connect right away to QEMU and send secrets even though the server is not running yet in the guest, which is unreliable. * gnu/build/secret-service.scm (secret-service-send-secrets): Add #:handshake-timeout. Read from SOCK an initial message from the server. Return #f on error. (secret-service-receive-secrets): Send 'secret-service-server' message to the client.
