Virtualizing on CentOS 8
I am trying to get going with CentOS 8.
In the past I would run qemu-system-x86_64 -hda myfile.img
get a console and off we go.
I dont with to use virt-manager and the gui and all - I just wish to have a

Is there something like that I'm not finding ?
I have found virsh - but I dont see how to make it run with an image file
from the command
