Message #8 received at 76488 <at> debbugs.gnu.org (full text, mbox):

From: Ludovic Courtès <ludo <at> gnu.org>

Subject: [PATCH 2/4] vm: ‘common-qemu-options’ splits command-line tokens.
Date: Sat, 22 Feb 2025 18:10:14 +0100

The result returned so far by ‘common-qemu-options’ assumed that it
would be passed to a shell.  This is the case when using
‘system-qemu-image/shared-store-script’ but possibly not in other cases.

* gnu/system/vm.scm (common-qemu-options): Add #:image-format.
[virtfs-option]: Return a list of strings instead of a single
"-virtfs xyz" string.  Update caller to use ‘append-map’.
Separate "-drive" string.
