Hi,
I’m runnig VyOS as KVM/QEMU and I am trying to document something.
Can I somehow copy what I see on my screen? How?
I mean as text.
Maybe it’s possible if connect via serial port with minicom or screen?
Yes, that’s a good idea. But now I am realizing I can do something even easier I did not even think of… ssh
Thank you!
If you are running qemu from the cli you could add the --no-graphics option, that will make ttyS0 to be pushed to stdin/out on the console that started qemu. 
The only thing to note about this is that qemu will be blocking until it exits.
Thank you the tip runar. But just by sshing into VyOS worked for me.
