Subject: [PATCH] guix system vm: Add --no-graphic CLI argument.
Date: Tue, 30 Nov 2021 20:13:13 +0100
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.

This looks fine. Could you send an updated patch with the associated
documentation update?

Thanks,

after consuling on #guix, i'm resending the two commits (the doc and
the code) as one, because that is preferred.

Hello,

Thanks for the v2. I think we should also remove the "-vga std" argument
that is added by "common-qemu-options" but ignored because "-nographic"
is read first in QEMU command line.

Subject: [PATCH v3] guix system vm: Add --no-graphic CLI argument.
Date: Fri,  3 Dec 2021 13:22:02 +0100
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.
(common-qemu-options): Remove '-vga stg'; it is the default since QEMU 2.2.
* 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.  Adde a paragraph to describe
--no-graphic.
---


v3: also remove the '-vga std' from the qemu command line; it's been the
default since forever.

Hello,

I pushed the v2, and a separate commit removing the "-vga std" argument.

Thanks,
