426f9772b8 Fix QEMU ARGV detection with kvm >= 85 2009-05-11 15:14:24 +00:00
Cole Robinson
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.
 2009-05-11 13:50:38 +00:00

27d72bd517 Report qemu log data if we fail to daemonize the process. 
This ensures the user will actually see 'hook' function error output.

Cole Robinson
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.

7ee54d8356 Changes needed for multiple graphics adapters 
* src/domain_conf.c src/domain_conf.h: parse and save multiple
  graphics elements instead of one, patch by Pritesh Kothari
* src/qemu_conf.c src/qemu_driver.c: adapt the qemu/kvm driver for
  the new structures, patch by Pritesh Kothari
* src/xend_internal.c src/xm_internal.c: same thing for Xen drivers

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.

4d3d0039e5 Convert all drivers to use old-style struct initializers; this makes a handy 
built-in TODO list for each driver.  Also rip out the internal getURI method;
it is never used by any of the drivers, and was buggy to boot.
