I am having an issue where my linux fedora 33 VM will become unresponsive. The cpu usage icon in the toolbar at the top shows red-100%, network access is lost, and when I click into the desktop in the VM the mouse is unresponsive as well. This leaves me unable to investigate what might be using 100% cpu. My thought was to enable the linux serial console using console= in my boot string. Has anyone figured out how to do that? When I configure passing one of my physical serial ports to the VM, then I can't open the same serial port with minicom, I get resource busy.
