[PVE-User] Serial console and proxmox-boot-tool...

[Marco Gaiarin]

Normally i define serial console (eg, virtual one, iDRAC or iLO) in grub
with:

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

and when i run 'update-grub' they warn me:

	root@sdpve2:~# update-grub
	Generating grub configuration file ...
	W: This system is booted via proxmox-boot-tool:
	W: Executing 'update-grub' directly does not update the correct configs!
	W: Running: 'proxmox-boot-tool refresh'

this settings are still effective? Or i need to setup these stuff
specifically for proxmox-boot-tool?

And if, where and how?


Thanks.

if the system is indeed booted with grub (legacy BIOS) instead of
systemd-boot (UEFI) - then you just need to run
`proxmox-boot-tool refresh` (as the warning suggests)

if the system is booted with systemd-boot - then you need to configure the
kernel commandline parameters in /etc/kernel/cmdline (instead of
/etc/default/grub) (see [0])- the bootloader screen itself will be on the
serial terminal, if it's configured in the UEFI/BIOS settings on the
machine itself.

I hope this helps!

OK, but /etc/kernel/cmdline and generally 'systemd-boot' seems totally
undocumented, so it is not clear how setup this...

Ah. Stop. Wait. What?!

Something like:
	https://techlibrary.hpe.com/docs/iss/proliant_uefi/UEFI_Gen9_121417/s_enable_BIOS_serial_console_port.html
for iLO and:

for iDRAC?!


Thanks.
