Yes, we can remove the CVS related info, they just got mailed to you
because I got the code from a fresh LTP CVS checkout!

You could re-write the above if statement using the form:
try:
utils.system(ntp_cmd)
except:
raise error.TestFail("NTP server has not started correctly")
Some comments:
1) The try/except block works because utils.system already throws an
exception when the exit code is different from 0.
2) The form
raise error.TestFail("NTP server has not started correctly")
Is preferred on the upstream project over the equivalent
raise error.TestFail, "NTP server has not started correctly"
But on kvm autotest we are adopting the later, so don't worry and keep
the all the raises the way they are on your original patch. This was
just a side comment.

Ok, will take a look at this. By the way, when you have an updated patch
please let us know!
