2022-01-14system: vm: Change the writable image name....* gnu/system/vm.scm (system-qemu-image/shared-store-script): Change it.
Mathieu Othacehe


2022-01-06system: vm: Restore default RAM size to 512MB....* gnu/system/vm.scm (system-qemu-image/shared-store-script): Restore it.
Mathieu Othacehe


2021-12-23Remove VM generation dead-code....This code duplicates the (gnu system image) and (gnu build image) code. Using
VM for image generation is not needed, not portable and really slow. Remove
all the VM image generation code to make sure that only the image API is used.

* gnu/build/vm.scm: Remove it. Move the qemu-command procedure to ...
* gnu/build/marionette.scm: ... here.
* gnu/local.mk (GNU_SYSTEM_MODULES): Adapt it.
* tests/modules.scm: Ditto.
* gnu/tests/install.scm: Ditto.
* gnu/system/vm.scm: Adapt it and remove expression->derivation-in-linux-vm,
qemu-img, system-qemu-image/shared-store and system-docker-image procedures.
* doc/guix.texi (G-Expressions): Adapt it.

2021-12-23system: vm: Use the image API to generate QEMU images....Also add a volatile? argument to the virtual-machine record. When volatile? is
true generate a QEMU script that mounts an overlay on top of a read only
storage. When volatile? is false, use a persistent, read-write storage.

* gnu/system/vm.scm (common-qemu-options): Add a rw-image? argument to use a
persistent storage.
(system-qemu-image/shared-store-script): Add a volatile? argument and honor
it. Use the image API to build the QEMU image.
(<virtual-machine>)[volatile?]: New field.
(virtual-machine-compiler): Pass the volatile? argument to the
system-qemu-image/shared-store-script procedure.

2021-12-05Merge remote-tracking branch 'origin/master' into core-updates-frozenRicardo Wurmus


2021-12-03system: vm: Remove the vga argument....* gnu/system/vm.scm (common-qemu-options): Remove the "-vga std" argument that
is the default since QEMU 2.2.

2021-12-03guix system vm: Add --no-graphic CLI argument....It configures QEMU to use the tty it was started in for IO (as opposed to
opening a separate graphical window).  This enables copy-pasting and
scrollback.  Exit QEMU with C-a x.

* gnu/system/vm.scm (system-qemu-image/shared-store-script): Also add the
'-nographic' QEMU argument when called with #:graphic? #false.
* guix/scripts/system.scm (system-derivation-for-action): Propagate
the #:graphic? keyword arg.
(perform-action): Add and propagate the #:graphic? keyword arg.
(show-help): Add --no-graphic CLI arg.
(%options): Process the new --no-graphic CLI arg.
(process-action): Feed in the CLI arg through the #:graphic? keyword arg.
* doc/guix.texi (Invoking guix system): Add example to combine guix system and
invoking the vm start script into one command.  Split the description of the
various options into separate paragraphs.  Add a paragraph to describe
--no-graphic.

2021-11-20vm: <virtual-machine> defaults to using 'qemu-minimal'....'qemu-minimal' is enough for system tests, which is the main (only?) use
of <virtual-machine>.

* gnu/system/vm.scm (<virtual-machine>)[qemu]: Default to QEMU-MINIMAL.
