libvirt users - May 2021 - Console of P2V?

I generally use

GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0,115200n8"

and redo grub.cfg (i.e. update-grub, grub2-mkconfig)

thanks for the pointer.

I literally ran in the guests commandline

??? GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0,115200n8"
??? sudo update-grub

which did change anything to the behavior on the hosts cli

?? Connected to domain '[domain]'
?? Escape character is ^] (Ctrl + ])

and then nothing

so ... what is the error I am making?
