Hello,

Thank you for your answer.

Actually, I already tried updating Grub with those parameters. No effect.

It looks to be a libvirt issue. I'm studying our libvirt configs and
templates now. It was found that libvirt uses a template with the following
line:

<cmdline>console=ttyS0</cmdline>

I suppose that I need to change it to tty1 as the last is shown on my VNC
console. I'll keep investigation.
