  as the current Xen dump

fe7cb869a8 qemu: Check driver is initialized up front, to avoid segfault.
If the qemu_driver was not initialized (possibly due to an error on driver
startup), we can segfault if attempting to connect to the URI.

62455ed872 Switch to using a unix socket for the qemu monitor
We keep support for the pty based monitor so that we can re-connect
to VMs started by older versions of libvirtd.

* src/domain_conf.c: handle formatting and parsing unix monitors

* src/qemu_driver.c: add qemudOpenMonitorUnix(), remove the monitor
  pty path searching from qemudFindCharDevicePTYs(), switch
  qemudStartVMDaemon() and qemuDomainXMLToNative() to using a unix
  monitor

* tests/qemuxml2argvtest.c: switch to using a unix monitor

* tests/qemuxml2argvdata/qemuxml2argv-*.args: update test data

05d377bdd2 Add the monitor type to the domain state XML
There are no functional changes in this patch apart from adding the
monitor type to the state XML.

The patch mostly consists of switching to use virDomainChrDef every
where to describe the monitor.

* src/domain_conf.h: replace monitorpath with monitor_chr

* src/domain_conf.c: handle parsing the monitor type and initializing
  monitor chr

* src/qemu_conf.[ch]: make qemudBuildCommandLine take a
  virDomainChrDefPtr and use that to build the -monitor parameter

* src/qemu_driver.c: split pty specific and common code from
  qemudOpenMonitor, have qemudStartVMDaemon() initialize monitor_chr

* tests/qemuxml2argvtest.c: update for qemudBuildCommandLine() change

8a52daa2d4 Don't leak vm->monitorpath on re-connect
* src/qemu_driver.c: vm->monitorpath is already initialized in the case
  of re-connect, so move the initialization for the normal startup case
  out of the common code

387935345c Fix memory reporting for inactive domains in the qemu driver.
Currently, 'info' will always report that mem = max mem. Make sure we
actually return the correct mem value.

53603043c7 Set default emulator in domain_conf.*, rather than the driver.
Rather than numerous instances of:

emulator = vm->def->emulator;
if (!emulator)
    emulator = virDomainDefDefaultEmulator(conn, vm->def, driver->caps);
if (!emulator)
    return -1;

Set this value at XML parse time in the domain config, so we can depend on
it for all future emulator accesses. There were unchecked accesses in the
qemu driver that were tripping up on this if no emulator was specified in
the XML, see:

34497fdb37 qemu_driver: Fix another domain startup error reporting race.
Parse the command line output a bit earlier so we have a better chance
of reporting the full error output on failure.

I hit this when QEMU would try to boot an invalid kernel (virtinst bug).

0c8a9d2d51 Check that QEMU is still alive while reading startup output.
By checking the pid every retry period, we can quickly determine if
the process crashed at startup, rather than make the user wait for
the entire timeout (3 seconds).

a331653dad Add pidfile argument to __virExec
virExec will write out the pid of the daemonized process only. Use this
in the QEMU driver, rather than QEMU's pidfile, so we can catch errors we
might miss if the emulator bails early.

79d9d2432f Add helper function virExecDaemonize
Wraps __virExec with the VIR_EXEC_DAEMON flag. Waits on the intermediate
process to ensure we don't end up with any zombies, and differentiates between
original process errors and intermediate process errors.

1d6c713b18 Fix qemu driver's interpretation of <hostdev managed='yes'/>
This change:

  Tue Mar  3 08:55:13 GMT 2009 Daniel P. Berrange <berrange@redhat.com>

       Don't try to detach & reset PCI devices while running test
       suite for XML-> ARGV conversion.
       * src/qemu_driver.c: Add qemuPrepareHostDevices() helper to
       detach and reset PCI devices.
       * src/qemu_conf.c: Don't detach & reset PCI devices while
       building the command line argv

accidentally did this:

-            if (hostdev->managed) {
+        if (!hostdev->managed) {

Which results in managed='yes' not causing the device to be
detached when the guest is starting.
