It is likely that you have to stop and start the VM any for your system to see the new config. I doubt you can hotplug a serial interface. With that in mind you could simpy dumpxml, stop the VM, edit the XML and restart the VM with the edited XML. Also as a point of reference, a coworker just mentioned the virsh ttyconsole command If the console is there it will tell you which one is configured. # virsh ttyconsole vm137 /dev/pts/1 otherwise it just exits(1). <blockquote type="cite" cite="mid:a8ecd56c-3d42-7952-2676-623f70c7a646@netcologne.de"> <blockquote type="cite" cite="mid:f6e0a7a6-679d-da5a-be50-ddc3df2cc2bb@pixelgate.net"> On 5/23/2021 12:52 AM, vrms wrote: <blockquote type="cite">hi William On 22.05.21 23:59, William wrote: <blockquote type="cite">I generally use GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0,115200n8" and redo grub.cfg (i.e. update-grub, grub2-mkconfig) </blockquote> thanks for the pointer.
