SOL activation on hypervisor

[DerDanilo]

How can be activate SOL properly so that it's reboot and update safe, since PVE seems to change kernel and some of it's parameters regularly.

Generally it should be similar on how to enable it on any Debian based system. (https://pve.proxmox.com/wiki/Serial_Terminal)
But how can be ensure that it's update safe?

hm? inhowfar?
the kernels (and also kernel series) do change quite regularly (due to security updates) , but AFAIK the SOL (I assume Serial over LAN) settings are usually done via bootloader config ('/etc/default/grub' , '/etc/kernel/cmdline' - see https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysboot)
and these don't get touched automatically by PVE.
In my experience you set this up once and then it just works

this howto should work more or less: https://cweiske.de/tagebuch/serial-console-debian9.htm

Hope this helps!
