Use the correct API sd_listen_fds to determine whether the process is

Change sd_booted to launched_by_systemd to avoid confusion with

There were two problems with original code:
1. sd_booted() was used to determined if the process was started by

2. Exit with error if pidfile was specified, which was too harsh.
These two combined made cxenstored unable to start by hand if it ran

Hi all,
I'm looking into xen's test suites now, and encounter some problems.
Does xen have unit tests that can be executed by xen contributors to

In xen-4.5.1(and its upstream), there are sevral test cases in the

Wall time obtained from do_gettimeofday is susceptible to sudden jumps due
