I try (qemu) info status, and shows the vm is running.

In this case, how can i determine if the system is successfully

You need to pass "console=ttyS0" or similar to tell systemd to
actually
activate a serial console. Console over serial is disabled by
default.
We should maybe change that in debian-installer.
Looking at the dmesg output, it looks like you're hitting the issue
where the bochs_drm module panics on load meaning that you end up with
no framebuffer unless you explicitly set the serial console as above.
I actually managed to debug this over the weekend and sent the patch
upstream (see
https://lists.freedesktop.org/archives/dri-devel/2017-July/145935.html)
so qemu-system-sparc64 should work fine with the bochs_drm framebuffer
when the 4.13 kernel comes out.
Adrian - next time you do a set of Debian images, would it be possible
to include this patch until it lands upstream?
ATB,
Mark.
I'm not sure if i really understand this.
Where should i put the option to enable console=ttyS0?
Is it the same if i change the -serial option on qemu-system-sparc64
command as the following?
(This require sudo, and nothing appear when i use minicom -D /dev/ttyS0
).
