55946f23a6 Fix PCI address handling when controllers are deleted
* src/qemu/qemu_driver.c: in qemudDomainDetachPciControllerDevice()
  when a controller is not present in the system anymore, the PCI
  address must be deleted from libvirt's hashtable because it can
  be re-used for other purposes.

24cc058e5e Fix data structure handling when controllers are attached
* src/qemu/qemu_driver.c: in qemudDomainAttachDevice(), one must not
  delete the data part when the operation succeeds because it is
  required later on. The correct pattern to handlethe parsed
  representation of the device information on success
  is dev->data.controller = NULL; virDomainDeviceDefFree(dev);,
  which leaves the structure pointed at by data in memory.

This extends the XML to allow for

  <clock offset='timezone' timezone='Europe/Paris'/>

This is useful if the admin has not configured any timezone on the
host OS, but still wants to synchronize a guest to a specific one.

* src/conf/domain_conf.h, src/conf/domain_conf.c: Support extra
  'timezone' attribute on clock configuration

200c83b29d Support variable clock offset mode in QEMU
This allows QEMU guests to be started with an arbitrary clock
offset

The test case can't actually be enabled, since QEMU argv expects
an absolute timestring, and this will obviously change every
time the test runs :-( Hopefully QEMU will allow a relative
time offset in the future.

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Use the -rtc arg
  if available to support variable clock offset mode
* tests/qemuhelptest.c: Add QEMUD_CMD_FLAG_RTC for qemu 0.12.1

b9e2967a5e Add new clock mode allowing variable adjustments
This introduces a third option for clock offset synchronization,
that allows an arbitrary / variable adjustment to be set. In
essence the XML contains the time delta in seconds, relative to
UTC.

  <clock offset='variable' adjustment='123465'/>

The difference from 'utc' mode, is that management apps should
track adjustments and preserve them at next reboot.

* src/conf/domain_conf.c, src/conf/domain_conf.h: Parse

The XML will soon be extended to allow more than just a simple
localtime/utc boolean flag. This change replaces the plain
'int localtime' with a separate struct to prepare for future
extension

1204e41f01 Only build virDomainObjFormat if not building proxy.
While building under RHEL-5, I got a compile warning because
virDomainObjFormat was defined but not used.  That came about
because in RHEL-5 we build with "#define PROXY", and
virDomainObjFormat is only used with !PROXY.  Move the
define.

8ac0334ebd Use standard spacing for user/pass prompt
Kind of minor, but it annoys me that the default auth callback
doesn't put a space between the prompt and the input, like a typical
terminal, ssh, etc. This patch changes the current prompt:

Please enter your authentication name:myuser

to

Please enter your authentication name: myuser

67b2eb1042 remote: Improve daemon startup error reporting
If I toggle enable_tcp in libvirtd.conf and add --listen in
/etc/init.d/libvirtd, I get the unhelpful error:

Starting libvirtd daemon: error: Unable to initialize network sockets.

Running without --daemon provides much more useful info:

sudo libvirtd --listen
11:29:26.117: error : remoteCheckCertFile:270 : Cannot access CA certificate '/etc/pki/CA/cacert.pem': No such file or directory

The daemon architecture makes it difficult to report this useful
info if daemonized, so point users to /var/log/messages and
dropping the --daemon flag if they want more info.

f4a43df52b Ignore SIGWINCH in remote client call to poll(2) (RHBZ#567931).
In bug 567931 we found that virt-top would exit occasionally
when the terminal window was resized.  Tracking this down it
turned out that SIGWINCH was being delivered to the process at
exactly the point where the libvirt remote driver was calling
poll(2) waiting for a reply from libvirtd.

This caused the poll(2) call to be interrupted (returning errno
EINTR).  However handling EINTR the same way as EAGAIN was not
the solution to this problem since we found previously that this
would break Ctrl-C handling (commit 47fec8eac2).

The correct solution is to mask out SIGWINCH for the duration
of the poll(2) system call.  The per-thread mask is changed and
restored immediately after the call.  Since we are using
pthread_sigmask, this should not affect other threads, and
since we restore the signal mask immediately afterwards it should
not affect the current thread visibly either.  Other possibly
problematic signals are SIGCHLD and SIGPIPE and these are
masked too.

Note use of ignore_value: It's not fatal if we cannot mask out
SIGWINCH, and in any case pthread_sigmask never fails on Linux
as long as you supply the correct arguments.

I tested this patch and it cures the original problem with
virt-top.
