30697181dc Fix autostart flag when loading running domains
Drivers load running persistent and transient domain configs before
inactive persistent domain configs, however only the latter would set a
domain's autostart flag. This mismatch between the loaded and on-disk
state could later cause problems with "virsh autostart":

  # virsh autostart example
  error: Failed to mark domain example as autostarted
  error: Failed to create symlink '/etc/libvirt/qemu/autostart/example.xml to '/etc/libvirt/qemu/example.xml': File exists

This patch ensures the autostart flag is set correctly even when the
domain is already defined.

3aab7f2d6b openvz: Fix regression in config file parsing
As reported by Diego Blanco in

  https://bugzilla.redhat.com/show_bug.cgi?id=702602

commit f0443765 which replaced openvz_readline to getline(3)
broke OpenVZ driver as it changed semantics of EOF-handling
when parsing OpenVZ configuration.

There're several other issues reported with current OpenVZ driver:

 #1: unclear error message when parsing "CPUS=" line
 #2: openvz driver goes into crashing loop
 #3: "NETIF=" line in configuration is not parsed correctly
 #4: aborts even when optional parameter is missing
 #5: there's a potential memory leak

This updated patch to fix #[145]. This patch does not fix #[23]
as I haven't verified these yet, but this at least got me to run
OpenVZ on libvirt once again.

18c2a59206 qemu: allow blkstat/blkinfo calls during migration
Originally most of libvirt domain-specific calls were blocking
during a migration.
A new mechanism to allow specific calls (blkstat/blkinfo) to be
executed in such condition has been implemented.
In the long term it'd be desirable to get a more general
solution to mark further APIs as migration safe, without needing
special case code.

 * src/qemu/qemu_migration.c: add some additional job signal
   flags for doing blkstat/blkinfo during a migration
 * src/qemu/qemu_domain.c: add a condition variable that can be
   used to efficiently wait for the migration code to clear the
   signal flag
 * src/qemu/qemu_driver.c: execute blkstat/blkinfo using the
   job signal flags during migration

a88916665d xen: check if device is assigned to guest before reattaching
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=664059

Reattaching pci device back to host without destroying guest or
detaching device from guest would cause host to crash. This patch adds
a check before doing device reattach. If the device is being assigned
to guest, libvirt refuses to reattach device to host. The patch only
works for Xen, for it just checks xenstore to get pci device
information.

454e50beee Fix gcc 4.6 warnings
gcc 4.6 warns when a variable is initialized but isn't used afterwards:

vmware/vmware_driver.c:449:18: warning: variable 'vmxPath' set but not used [-Wunused-but-set-variable]

This patch fixes these warnings. There are still 2 offending files:

- vbox_tmpl.c: the variable is used inside an #ifdef and is assigned several
  times outside of #ifdef. Fixing the warning would have required wrapping
  all the assignment inside #ifdef which hurts readability.

vbox/vbox_tmpl.c: In function 'vboxAttachDrives':
vbox/vbox_tmpl.c:3918:22: warning: variable 'accessMode' set but not used [-Wunused-but-set-variable]

  didn't want to dive into the code generator

33da939b0f Allow relative path for qemu backing file
This patch enables the relative backing file path support provided by
qemu-img create.

If a relative path is specified for the backing file, it is converted
to an absolute path using the storage pool path. The absolute path is
used to verify that the backing file exists. If the backing file exists,
the relative path is allowed and will be provided to qemu-img create.

Currently libvirt's default logging is limited and it is difficult to
determine what was happening when a proglem occurred (especially on a
machines where one don't know the detail.)  This patch helps to do that
by making additional logging available for the following events:

  creating/defining/undefining domains
  creating/defining/undefining/starting/stopping networks
  creating/defining/undefining/starting/stopping storage pools
  creating/defining/undefining/starting/stopping storage volumes.

a43c7338d8 bridge: Fix generation of dnsmasq's --dhcp-hostsfile option

  <bridge name='virbr1' stp='on' delay='0' />

    </dhcp>
  </ip>
</network>

But due to the wrong if-statement the argument --dhcp-hostsfile doesn't get
added to the dnsmasq command. The patch below fixes it for me.
