When accessing libvrtd remotely, polkit can't be used unless you are
logged as root. Instead allow libvirt groups member access to the
control socket.
* gnu/services/virtualization.scm (libvirt-configuration)
[unix-sock-group]: Change default from "root" to "libvirt".
* gnu/services/virtualization.scm (libvirt-configuration): Add 'qemu'
field.
(libvirt-service-type): Replace 'qemu' package with the one specified in
the service configuration.
The i486 target has been removed from qemu since at least 5.2.0.
* gnu/services/virtualization.scm (%i486): Remove variable.
(%qemu-platforms): Remove it.
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".
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.
* 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.

* 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).
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.
This is a follow-up to commit d692ebf980.
* gnu/services/virtualization.scm (%hurd-vm-accounts)[supplementary-groups]:
Add ’kvm’.
* gnu/services/virtualization.scm (hurd-vm-shepherd-service): Use #:group
"kvm"
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. Close SOCK upon timeout.
* gnu/services/virtualization.scm (hurd-vm-shepherd-service): 'start'
method returns #f when 'secret-service-send-secrets' returns #f.
* gnu/services/virtualization.scm (initialize-hurd-vm-substitutes)
(hurd-vm-activation): New procedures.
(hurd-vm-service-type)[extensions]: Add ACTIVATION-SERVICE-TYPE
extension.
* doc/guix.texi (Transparent Emulation with QEMU): Mention GNU/Hurd.
(The Hurd in a Virtual Machine): Explain which files are automatically
installed and mention offloading.
This change allows a childhurd to run within Guix System in a VM.
* gnu/services/virtualization.scm (hurd-vm-shepherd-service)[vm-command]:
Stage the 'file-exists?' call.
Until qemu was running as "root", which is unnecessary.
* gnu/services/virtualization.scm (%hurd-vm-accounts): New variable.
(hurd-vm-service-type)[extensions]: Add ACCOUNT-SERVICE-TYPE extension.
* gnu/services/virtualization.scm (secret-service-operating-system): New
procedure.
(hurd-vm-disk-image): Use it to ensure a Childhurd always includes the
secret-service.
(%hurd-vm-operating-system): Remove secret-service.
Co-authored-by: Ludovic Courtès <ludo@gnu.org>
* gnu/services/virtualization.scm (%hurd-vm-operating-system): Add
secret-service.
(hurd-vm-shepherd-service): Use it to install secrets.
* doc/guix.texi (The Hurd in a Virtual Machine): Document it.
This adds a "secret-service" that can be added to a Childhurd VM to receive
out-of-band secrets (keys) sent from the host.

* gnu/services/virtualization.scm (secret-service-activation): New procedure.
(secret-service-type): New variable.
* gnu/build/secret-service.scm: New file.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add it.
* gnu/services/virtualization.scm (<hurd-vm-configuration>)[options]: Remove
"--hda" option.
[id,net-options]: New fields.
(hurd-vm-net-options): New procedure. Parameterize port forwarding with ID.
* gnu/services/virtualization.scm (hurd-vm-shepherd-service): Use them.
Parameterize provision with ID, if set. Hardcode "--hda" option for image.
* doc/guix.texi (Virtualization Services): Document new fields. Update for
hardcoding of "--hda".
* gnu/services/virtualization.scm (hurd-vm-shepherd-service,
hurd-vm-disk-image): New procedures.
(%hurd-vm-operating-system, hurd-vm-service-type): New variables.
(<hurd-vm-configuration>): New record type.
* doc/guix.texi (Virtualization Services): Document it.
* gnu/services/shepherd.scm (scm->go): Use let-system, remove FIXME. Fixes
fixes cross-building of shepherd modules for the Hurd image.
* gnu/services/virtualization.scm (libvirt-shepherd-service): Add sbin to
the PATH variable, as ip binary is installed there.

As defaulting by stderr, along with the shepherd service not directing the
output to a log file makes seeing the output difficult, compared to logging to
syslog.
* gnu/services/virtualization.scm (libvirt-configuration)[log-outputs]: Change
default from "3:stderr" to "3:syslog:libvirtd".
This is a followup to ef640db2f5.
* gnu/services/virtualization.scm (libvirt-shepherd-service): Set
'#:environment-variables' for 'make-forkexec-constructor'.
This reverts commit 903e051a71 to fix
<https://bugs.gnu.org/31365>. The full path of the 'ip' command is already
embedded, and we want to search 'qemu' in PATH.
* gnu/packages/virtualization.scm (libvirt): Remove 'wrap-libvirtd phase. Add
configure flags to run qemu as 'nobody:kvm'.
* gnu/services/virtualization.scm (libvirt-service-type): Add 'qemu' to the
system profile.
* gnu/services/virtualization.scm: New file.
* doc/guix.texi (Virtualization Services): Document it.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add it.
