44342a0efe build: use re-entrant functions in virsh
Yesterday's commit 15d2c9f pointed out that virsh was still using
localtime(), which is not thread-safe, even though virsh is
definitely multi-threaded.  Even if we only ever triggered it from
one thread, it's better safe than sorry for maintenance purposes.

* cfg.mk (exclude_file_name_regexp--sc_prohibit_nonreentrant):
Tighten the rule.
* tools/virsh.c (vshOutputLogFile): Avoid localtime.
(vshEditWriteToTempFile, vshEditReadBackFile, cmdCd, cmdPwd)
(vshCloseLogFile): Avoid strerror.
* tools/console.c (vshMakeStdinRaw): Likewise.
* tools/virsh-domain.c (vshGenFileName): Fix spacing in previous
patch.

15d2c9fad4 Pass a correct pointer type to localtime_r(3).

Most likely this problem arose because of the patch I pushed
in gnulib commit e07d7c40f3ca5ec410cf5aa6fa03cfe51e712039.
Previously, gnulib required timeval's tv_sec to be
the same size as time_t.  But now, it requires only that
tv_sec be big enough to hold a time_t.

This patch was needed for Emacs.  Without the patch, gnulib
replaced struct timeval on OpenBSD, and this messed up
utimens.c, and Emacs wouldn't build.

Alternatively, gnulib could substitute its own struct timeval
for the system's, wrapping every struct timeval-using function
(gettimeofday, futimesat, futimes, lutimes, etc.  That'd be
more work, though.  And it would introduce some performance
issues with gettimeofday, which is supposed to be fast.

I've been trying to get away from using struct timeval,
and to use the higher-resolution struct timespec instead,
so messing with these obsolescent interfaces has been
lower priority for me.  But if someone wants to take the
more-ambitious approach that'd be fine, I expect.

For this particular case, though, how about if we avoid
the problem entirely?  libvirt doesn't need to use struct
timeval here at all.  It makes libvirt smaller and probably
faster, and it ports to OpenBSD without messing with gnulib.

67f83cd497 virsh: remove unneeded usage of vshConnectionUsability()
Now that vshCommandRun() checks for the connection automaticaly, remove
all of the redundant checks in the code.

vshConnectionUsability() no longer needs to be exported and this patch
marks it static.

70e608918e virsh: Improve checking for connection when running commands
Almost each virsh command uses the function vshConnectionUsability
before doing anything, to check if the connection is "alive".  Commands
that don't need an conection are already conveniently marked with
VSH_CMD_FLAG_NOCONNECT. We can automaticaly check for the connection
before calling any remote command so we don't forget to do so.

This patch also upgrades the connection check to use virConnectIsAlive
along with the current approach.

c18dc28b1f output status information during guest shutdown again
Since the move to systemd libvirt-guests doesn't output this progress
information anymore. This patch brings back this feature.

It is helpful to show the admin what the system is waiting for and what
is left of the timeout (e.g. for calibrating the shutdown timing of a ups).

Rewriting the current line with \r doesn't work anymore in the context
of systemd. So always write new lines, but move to 5 second intervals
to avoid flooding the console.

here is that --help isn't listed as an option in the actual 'help <cmd>'

79ca7e4e57 libvirt-guests: systemd host shutdown does not work
I originally postet this into the Fedora bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=843836

Currently gracefully shutting down guest vms on host shutdown does not work on
Fedora 17, the guests are killed hard on system shutdown.

The reason is systemd considers libvirt-guests.service to be stopped when the
system is running:

$ systemctl status libvirt-guests.service
libvirt-guests.service - Suspend Active Libvirt Guests
          Loaded: loaded (/usr/lib/systemd/system/libvirt-guests.service;
enabled)
          Active: deactivating (stop) since Fri, 27 Jul 2012 15:47:31 +0200;
2min 48s ago
         Process: 1085 ExecStart=/etc/init.d/libvirt-guests start
(code=exited, status=0/SUCCESS)
         Control: 1150 (libvirt-guests)
          CGroup: name=systemd:/system/libvirt-guests.service
                  └ control
                    ├ 1150 /bin/sh /etc/init.d/libvirt-guests stop
                    └ 2257 sleep 1

libvirt-guests.service is defined as type "simple" in systemd (the default).
That means systemd will shut down the service when the start executable is
terminated after starting is done. Systemd will not call stop again on system
shutdown because it thinks it is already stopped.

The solution is to define it as type "oneshot" and set the flag
"RemainAfterExit". Then systemd will consider the service as active after
startup and will call the stop function on host shutdown.
