[Bug 1391942] Re: Unnecessary events option of the trace argument with UST backend

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to another 
system. For this we need to know which bugs are still valid and which could be 
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Or mark it as "Fix Released" if the problem has been solved with a 
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
  Unnecessary events option of the trace argument with UST backend

Status in QEMU:
  Incomplete

Bug description:
  When running configure with the --enable-trace-backends=ust option and 
compiling. 
  The user should not have to specify a the "events" and "file" options because 
they are not used with that tracing framework.

  Right now, in order the use this option the need to specify a dummy
  events file.

  This fails:
  $> qemu-system-x86_64 -hda debian_wheezy_amd64_standard.qcow2 -trace -m 512
  qemu-system-x86_64: -trace -m: Invalid parameter '-m'

  This works:
  $> qemu-system-x86_64 -hda debian_wheezy_amd64_standard.qcow2 -trace 
events=dummy-events.txt -m 512
  VNC server running on `127.0.0.1:5900'

  I am using version:
  $> qemu-system-x86_64 --version
