Hello, On my Guix System machine, the ‘qemu-system-x86_64’ spawned by ‘guix system vm’ hangs after printing “Booting from ROM...”; it has to be terminated with SIGKILL, SIGINT is not enough.
Specifically: $(guix time-machine --commit=66188398c446bdf9ce044fa539536e9b54c28c60 \ -- system vm gnu/system/examples/bare-bones.tmpl) -m 1024 # Good. … whereas: $(guix time-machine --commit=9923100a42ffa80f604c1c13a5e999e6a4c15146 \ -- system vm gnu/system/examples/bare-bones.tmpl) -m 1024 # Bad! I thought the culprit might be this commit: commit 9923100a42ffa80f604c1c13a5e999e6a4c15146 Date: Fri Dec 23 09:42:27 2022 +0200 gnu: sgabios: Fix build on cross-build architectures. * gnu/packages/firmware.scm (sgabios)[arguments]: When cross-building add a make-flag to use the correct objcopy. … but even after reverting it on today’s master, QEMU occasionally hangs as before, though not always. ‘qemu-minimal’ as used for “make check-system” seems to work fine. There have been a number of packages unbundled, so I wonder if another one of these might be causing problems. What do you think? Ludo’.
