* gnu/system/vm.scm (expression->derivation-in-linux-vm) [user-builder]: Define in non-monadic style as 'program-file'. [loader]: Likewise, and 'execl' USER-BUILDER instead of loading it. (system-docker-image): Pass BUILD as the second argument to 'expression->derivation-in-linux-vm'. (make-iso9660-image, qemu-image): Remove call to 'reboot'.
2018-06-14store-copy: 'read-reference-graph' returns a list of records.Ludovic Courtès
The previous implementation of 'read-reference-graph' was good enough for many use cases, but it discarded the graph structure, which is useful information in some cases. * guix/build/store-copy.scm (<store-info>): New record type.

2018-05-28file-systems: Remove 'title' field and add <file-system-label>.Ludovic Courtès
The 'title' field was easily overlooked and was an endless source of confusion.

Fixes <https://bugs.gnu.org/30667>. Reported by Björn Höfling <bjoern.hoefling@bjoernhoefling.de>. * gnu/system/vm.scm (file-system->mount-tag): Use 'sha1' to compute the tag.
2018-03-03linux-initrd: Add virtio modules to '%base-initrd-modules'.Ludovic Courtès
Fixes a regression in installation tests, whereby 'guix system init' would report that virtio modules are missing for the target devices. In practice virtio modules were always available since 'base-initrd' was always called with #:virtio? #t. This commit simply moves them to '%base-initrd-modules' so that 'guix system' knows they're available. Reported by Danny Milosavljevic <dannym@scratchpost.org> at <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30629#112>. * gnu/system/linux-initrd.scm (default-initrd-modules): Add virtio modules.

Fixes a regression introduced in bc499b113a598c0e7863da9887a4133472985713, whereby the default initrd used by 'expression->derivation-in-linux-vm' would lack all the usual modules: virtio, nls_iso8859-1, etc. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Pass #:linux-modules to 'base-initrd'.
2018-01-19gnu: Consistently Write ‘file system(s)’.Tobias Geerinckx-Rice
It is the GNU way. * doc/guix.texi (Build Systems, DNS Services): Write ‘file system(s)’. * gnu/build/vm.scm (create-ext-file-system, create-fat-file-system): Likewise. * gnu/packages/backup.scm (dirvish, rsnapshot)[description]: Likewise. * gnu/packages/check.scm (python-testpath)[description]: Likewise. * gnu/packages/disk.scm (pydf)[description]: Likewise. * gnu/packages/file-systems.scm (disorderfs)[synopsis, description]: Likewise.

2018-01-07vm: 'vm-image' images refer to the root file system by UUID.Ludovic Courtès
This avoids the hard-coded "/dev/sda1", which only made sense when the image is run with "qemu-system-x86_64 -hda", not when it's passed to Xen, etc. Reported by Andreas Enge <andreas@enge.fr>. * gnu/system/vm.scm (system-qemu-image): Define 'root-uuid', use it as the 'device' field for "/", and pass it to 'qemu-image'.
2017-12-18vm: Pass the host's /dev/urandom to the guest at /dev/hwrng.Leo Famulari
* gnu/build/vm.scm (load-in-linux-vm): Use QEMU's virtio-rng-pci. * gnu/system/vm.scm (common-qemu-options): Likewise.
2017-12-17gnu: system: vm: Use loose cache for 9p file system.Christopher Baines
This improves the performance of the shared store for operations involving lots of files, e.g. searching through the store. * gnu/system/vm.scm (mapping->file-system): Add cache=loose to options.
2017-12-15bootloader: Factorize write-file-on-device.Mathieu Othacehe

2017-12-15vm: Adapt qemu command to ARM.Mathieu Othacehe
* gnu/build/vm.scm (load-in-linux-vm): New argument #:target-arm32. Use it to adapt command for qemu-system-arm. This implies to choose a machine ("virt"), use the correct console port "ttyAMA0", disable KVM use that is buggy on some ARM boards (Odroid XU4 for example) and use user mode network stack instead of NIC. Gather all those options in a new variable "arch-specific-flags". * gnu/system/vm.scm (expression->derivation-in-linux-vm): Pass to load-in-linux-vm "#:target-arm32?" argument.
2017-12-04bootloader: extlinux: Stop using dd binary.Mathieu Othacehe
* gnu/bootloader/extlinux.scm (dd): Remove it, (install-extlinux): replace dd call by Guile I/O procedures. * gnu/system/vm.scm (qemu-image): Add (ice-9 binary-ports) to used-modules list to provide "get-bytevector-n" and "put-bytevector". * guix/scripts/system.scm (bootloader-installer-derivation): Ditto.
2017-12-02system: vm: Fix typo in comment.Mathieu Othacehe
* gnu/system/vm.scm (qemu-image): Fix typo targetting -> targeting.
2017-12-01system: vm: Do not add EFI partition on ARM system.Mathieu Othacehe
* gnu/system/vm.scm (qemu-img): Do not add EFI partition if we are targetting ARM. UEFI support on u-boot is still experimental, so do not add EFI partition on ARM for now.
2017-11-30vm: Filter out file systems that refer to UUIDs or labels.Ludovic Courtès
* gnu/system/vm.scm (virtualized-operating-system)[user-file-systems]: Filter out things that refer to file system UUIDs or labels.
2017-11-26vm: Use os-defined initrd intead of base-initrd.Mathieu Othacehe
* gnu/system/vm.scm (system-disk-image, system-qemu-image, virtualized-operating-system): Replace base-initrd by (operating-system-initrd os). The system produced were always using base-initrd even if the user had defined a custom initrd based on raw-initrd in the os declaration.
2017-11-06system: vm: Use 2^32 - 1 as hash size.Mathieu Othacehe
* gnu/system/vm.scm (operating-system-uuid): Use 2^32 - 1 instead of 2^32 as hash size. On some 32 bit system (ARM for example), 2^32 exceeds hash max size (ULONG_MAX = 2^32 - 1).
2017-10-19vm: Always use GRUB/i386.Ludovic Courtès
Fixes <https://bugs.gnu.org/28768>. Reported by Oleg Pykhalov <go.wigust@gmail.com>. * gnu/system/vm.scm (virtualized-operating-system): Override the 'bootloader' field.

2017-10-04vm: Add a minimum root size.Christopher Baines
* gnu/system/vm.scm (qemu-image): When guessing the root-size, use a lower bound of 20 MiB, otherwise the root file system size is sometimes 0 MiB in size.
2017-09-11vm: Generate a UUID to identify the root file system.Ludovic Courtès
This makes collisions less likely than when using a label to look up the partition. See <https://bugs.gnu.org/27735>. * gnu/system/vm.scm (operating-system-uuid): New procedure. (system-disk-image): Define 'root-uuid' and use it for the root file system. Pass it to 'iso9660-image' and 'qemu-image'.
2017-09-11vm: Allow users to specify a UUID for the root partition.Ludovic Courtès
* gnu/system/vm.scm (qemu-image): Add #:file-system-uuid parameter; pass it as the 'uuid' field of the root partition.
2017-09-11system: Introduce a disjoint UUID type.Ludovic Courtès
Conceptually a UUID is just a bytevector. However, there's software out there such as GRUB that relies on the string representation of different UUID types (e.g., the string representation of DCE UUIDs differs from that of ISO-9660 UUIDs, even if they are actually bytevectors of the same length). This new <uuid> record type allows us to preserve information about the type of UUID so we can eventually convert it to a string using the right representation. * gnu/system/uuid.scm (<uuid>): New record type. (bytevector->uuid): New procedure. (uuid): Return calls to 'make-uuid'. (uuid->string): Rewrite using 'match-lambda*' to accept a single 'uuid?' argument. * gnu/bootloader/grub.scm (grub-root-search): Check for 'uuid?' instead of 'bytevector?'. * gnu/system.scm (bootable-kernel-arguments): Check whether ROOT-DEVICE is 'uuid?'. (read-boot-parameters): Use 'bytevector->uuid' when the store device is a bytevector. (read-boot-parameters-file): Check for 'uuid?' instead of 'bytevector?'. (device->sexp): New procedure. (operating-system-boot-parameters-file): Use it for 'root-device' and 'store'. (operating-system-bootcfg): Remove conditional in definition of 'root-device'. * gnu/system/file-systems.scm (file-system->spec): Check for 'uuid?' on DEVICE and take its bytevector. * gnu/system/mapped-devices.scm (open-luks-device): Likewise. * gnu/system/vm.scm (iso9660-image): Call 'uuid-bytevector' for the #:volume-uuid argument.
2017-09-06vm: Call iso9660-image with #:register-closures? as #t.Christopher Baines
* gnu/system/vm.scm (system-disk-image): Call iso9660-image with #:register-closures? as #t.
2017-09-06vm: Add support for registering closures to iso9660-image.Christopher Baines
* gnu/system/vm.scm (iso9660-image): Add support for registering closures.

2017-07-18vm: 'iso9660-image' produces a single-file output.Ludovic Courtès
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Add #:single-file-output? and pass it to 'load-in-linux-vm'. (iso9660-image): Pass #:single-file-output? to 'expression->derivation-in-linux-vm'. * gnu/build/vm.scm (load-in-linux-vm): Add #:single-file-output? and honor it.
2017-07-17build, vm: Use a less common label.Tobias Geerinckx-Rice
