[PVE-User] iDRAC, virtual serial console, boot log.

[PVE-User] iDRAC, virtual serial console, boot log.

[Marco Gaiarin]

I come back on this topic, because i need some clarification.

I was used (on iLO, indeed, but is the same) to have virtual serial console
on ssh, enabled on all boot phase (POST, boot loader, kernel boot, logon).

I'm trying to enable it on a PVE6 on a dell PowerEdge T440 server, and i can
access POST, boot loader and logon. I've lost kernel boot, that is indeed a
useful thing. ;-)

With GRUB i was used to add to /etc/default/grub (and i've tried also in
systemd-bootd, with no luck):

	GRUB_TERMINAL="console serial"
	GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200"

how can i set console in systemd-boot?!


Thanks.

this should work out of the box - no special config needed
(at least it does on a R630 I run, and a virtual machine I just tested it
with)

I hope this helps!

It does not. As just stated, i see on serial console the bios messages,
then the boot loader countdown, then nothing for some seconds and then
the issue/login.

If i run on the same time the HTML5 console, i can see all the
kernel/systemd cheatchat.

See https://pve.proxmox.com/wiki/Host_Bootloader

Edit /etc/kernel/cmdline and add appropriate parameters (e.g. console=tty console=ttyS0,115200n8),
then run "proxmox-boot-tool refresh".

Sorry for the misunderstanding - I read that systemd-boot does not show
anything - but the boot-loader countdown is what systemd-boot displays -
so that part is working.

the part that seems missing from your explanation is the kernel-output -
As the others in the thread suggested - you need to adapt the kernel
commandline for this - /etc/kernel/cmdline (for systemd-boot):
https://pve.proxmox.com/pve-docs/chapter-sysadmin.html#sysboot_edit_kernel_cmdline

and configure the console= to point to the correct serial terminal - see
e.g.
https://wiki.archlinux.org/title/working_with_the_serial_console#Kernel
