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.
