Qemu vm crashed with message 'Terminating on signal 1'

Question

I have a qemu vm that shutdown for some reason. The only log I have on qemu is:

qemu: terminating on signal 1 from pid xxxxx

Do you know what signal 1 is ?

Answer 1

man 7 signal:

  SIGHUP        1       Term    Hangup detected on controlling terminal
                                 or death of controlling process

Perhaps the terminal was closed, the session logged out or something like that.
