gnu/system/vm.scm (common-qemu-options): Remove the "-vga std" argument that is the default since QEMU 2.2. Suggested-by: Attila Lendvai <attila@lendvai.name> Mathieu Othacehe 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. Signed-off-by: Mathieu Othacehe <othacehe@gnu.org> Attila Lendvai 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.
