Allow libvirt-guests to stage a delay between guest startups,
to avoid system load caused by back-to-back startup.

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]

- esx_vi_types.generated.c: the name implies it's generated code and I
  didn't want to dive into the code generator

esx/esx_vi_types.generated.c: In function 'esxVI_FileQueryFlags_Free':
esx/esx_vi_types.generated.c:1203:3: warning: variable 'item' set but not used [-Wunused-but-set-variable]

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.

* AUTHORS: add Naoya Horiguchi
* src/network/bridge_driver.c src/qemu/qemu_driver.c
  src/storage/storage_driver.c: provide more VIR_INFO logging

* AUTHORS: Update, to satisfy 'make syntax-check'.

The current description suggests that you always have to provide
a valid typeVer pointer. But if you want only the libvirt version
it's also possible to set type and typeVer to NULL to skip the
hypervisor part.

When compiling libvirt with GCC 3.4.6 the following warning is being triggered quite a lot:

util/memory.h:60: warning: declaration of 'remove' shadows a global declaration
/usr/include/stdio.h:175: warning: shadowed declaration is here

Fix this by renaming the parameter to 'toremove'.

Depending if the qemu binary supports multiple pci-busses, the device
options will contain "bus=pci" or "bus=pci.0".

Only x86_64 and i686 seem to have support for multiple PCI-busses. When
a guest of these architectures is started, set the
QEMUD_CMD_FLAG_PCI_MULTIBUS flag.

bugfix for https://bugzilla.redhat.com/show_bug.cgi?id=671050

virsh simply refutes to detach-interface in case when multiple
interfaces are attached and --mac is not specified.

I added a host definition to a network definition:

<network>
  <name>Lokal</name>
  <uuid>2074f379-b82c-423f-9ada-305d8088daaa</uuid>
  <bridge name='virbr1' stp='on' delay='0' />
  <ip address='192.168.180.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.180.128' end='192.168.180.254' />
      <host mac='23:74:00:03:42:02' name='somevm' ip='192.168.180.10' />
    </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.

While not technically a double free (since VIR_FREE NULLs the
pointer), this is unnecessary extra code.

This crept in when the function was converted from virRun to virCommand.

The AUTHORS file has also been updated.

Current code does not pass VM mac address to a 802.1Qbh direct attach
interface using IFLA_VF_MAC.  This patch adds support in macvtap code to
send IFLA_VF_MAC netlink request during port profile association on a
802.1Qbh interface.

Stefan Cc'ed for comments because this patch changes a condition for
802.1Qbg

802.1Qbh support for IFLA_VF_MAC in enic driver has been posted and is
pending acceptance at http://marc.info/?l=linux-netdev&m=129185244410557&w=2

Changes common to all network disks:
-Make source name optional in the domain schema, since NBD doesn't use it
-Add a hostName type to the domain schema, and use it instead of genericName, which doesn't include .
-Don't leak host names or ports
-Set the source protocol in qemuParseCommandline

This patch adds network disk support to libvirt/QEMU.  The currently
supported protocols are nbd, rbd, and sheepdog.  The XML syntax is like
this:

    <disk type="network" device="disk">
      <driver name="qemu" type="raw" />
      <source protocol='rbd|sheepdog|nbd' name="...some image identifier...">
        <host name="mon1.example.org" port="6000">
        <host name="mon2.example.org" port="6000">
        <host name="mon3.example.org" port="6000">
      </source>
      <target dev="vda" bus="virtio" />
    </disk>

When libvirt-guests is being stopped, I get the following message:
$Running guests on default URI: test-vm
$Suspending guests on default URI...
$Suspending test-vm: /etc/init.d/libvirt-guests: 340: Syntax error: Bad fd

When dumping a domain, it's reasonable to save dump-file in raw format
if dump format is misconfigured or the corresponding compress program
is not available rather then fail dumping.

When we set migrate_speed by json, we receive the following
error message:
libvirtError: internal error unable to execute QEMU command
'migrate_set_speed': Invalid parameter type, expected: number

The reason is that: the arguments of migrate_set_speed
by json is json number, not json string.

In origin code, double quote is only allowed at the begin or end
"complicated argument"
--some_opt="complicated string"  (we split this argument into 2 parts,
option and data, the data is "complicated string").

This patch makes it allow double quote at any position of
an argument:
complicated" argument"
complicated" "argument
--"some opt=complicated string"

This patch is also needed for the following patches,
the following patches will not split option argument into 2 parts,
so we have to allow double quote at any position of an argument.

Public api to set/get memory tunables supported by the hypervisors.

dv:
* some cleanups in libvirt.c
* adding extra checks in libvirt.c new entry points

v4:
* Move exporting public API to this patch
* Add unsigned int flags to the public api for future extensions

v3:
* Add domainGetMemoryParamters and NULL in all the driver interface

v2:
* Initialize domainSetMemoryParameters to NULL in all the driver
  interface structure.

As recommended by Eric. :)

* docs/drvlxc.html.in: Use correct VM name, and mention that
libvirt_lxc might be in an alternate location.
