6e41f30efc Implement managed save operations for qemu driver
The images are saved in /var/lib/libvirt/qemu/save/
and named $domainname.save . The directory is created appropriately
at daemon startup. When a domain is started while a saved image is
available, libvirt will try to load this saved image, and start the
domain as usual in case of failure. In any case the saved image is
discarded once the domain is created.

* src/qemu/qemu_conf.h: adds an extra save path to the driver config
* src/qemu/qemu_driver.c: implement the 3 new operations and handling
  of the image directory

598a0c00dc Support vhost-net mode at qemu startup for virtio network devices
Attempt to turn on vhost-net mode for devices of type NETWORK, BRIDGE,
and DIRECT (macvtap).

* src/qemu/qemu_conf.h: add vhostfd to qemuBuildHostNetStr prototype
  add qemudOpenVhostNet prototype new flag to set when :,vhost=" found in
  qemu help
* src/qemu/qemu_conf.c: * set QEMUD_CMD_FLAG_VNET_HOST is ",vhost=" found
  in qemu help
   - qemudOpenVhostNet - opens /dev/vhost-net to pass to qemu if everything
     is in place to use it.
   - qemuBuildHostNetStr - add vhostfd to commandline if it's not empty
     (higher levels decide whether or not to fill it in)
   - qemudBuildCommandLine - if /dev/vhost-net is successfully opened, add
     its fd to tapfds array so it isn't closed on qemu exec, and populate
     vhostfd_name to be passed in to commandline builder.
* src/qemu/qemu_driver.c: add filler 0 for new arg to qemuBuildHostNetStr,
  along with a note that this must be implemented in order for hot-plug of
  vhost-net virtio devices to work properly (once qemu "netdev_add" monitor
  command is implemented).

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
* qemuxml2argvdata/qemuxml2argv-clock-variable.args,
  qemuxml2argvdata/qemuxml2argv-clock-variable.xml,
  qemuxml2argvtest.c: Test case, except we can't actually enable
  it yet.

e52687e88f macvtap IFF_VNET_HDR configuration
This patch sets or unsets the IFF_VNET_HDR flag depending on what device
is used in the VM. The manipulation of the flag is done in the open
function and is only fatal if the IFF_VNET_HDR flag could not be cleared
although it has to be (or if an ioctl generally fails). In that case the
macvtap tap is closed again and the macvtap interface torn.

7357975000 Fix disk stats retrieval with QEMU >= 0.12
With QEMU >= 0.12 the host and guest side of disks no longer have
the same naming convention. Specifically the host side will now
get a 'drive-' prefix added to its name. The 'info blockstats'
monitor command returns the host side name, so it is neccessary
to strip this off when looking up stats since libvirt stores the
guest side name !

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Move 'drive-' prefix
  string to a defined constant
* src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_text.c: Strip

0943048ad0 Remove direct storage of hostnet_name & vlan
The current way of assigning names to the host network backend and
NIC device in QEMU was over complicated, by varying naming scheme
based on the NIC model and backend type. This simplifies the naming
to simply be 'net0' and 'hostnet0', allowing code to easily determine
the host network name and vlan based off the primary device alias
name 'net0'. This in turn allows removal of alot of QEMU specific
code from the XML parser, and makes it easier to assign new unique
names for NICs that are hotplugged

* src/conf/domain_conf.c, src/conf/domain_conf.h: Remove hostnet_name
  and vlan fields from virNetworkDefPtr
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h, src/qemu/qemu_driver.c:

  or backend type. Determine VLANs from the alias name.

9258ec0a2e Rewrite way QEMU PCI addresses are allocated
The current QEMU code allocates PCI addresses incrementally starting
at 4. This is not satisfactory because the user may have given some
addresses in their XML config, which need to be skipped over when
allocating addresses to remaining devices.

It is thus neccessary to maintain a list of already allocated PCI
addresses and then only allocate ones that remain unused. This is
also required for domain device hotplug to work properly later.

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add APIs for creating
  list of existing PCI addresses, and allocating new addresses.
  Refactor address assignment to use this code
* src/qemu/qemu_driver.c: Pull PCI address assignment up into the
  qemuStartVMDaemon() method, as a prelude to moving it into the
  'define' method. Update list of allocated addresses when connecting
  to a running VM at daemon startup.

5d462bd0b3 Implement CPU topology support for QEMU driver
QEMU's command line equivalent for the following domain XML fragment

    <cpu ...>
        ...
        <topology sockets='1' cores='2', threads='1'/>

is

    -smp 2,sockets=1,cores=2,threads=1

This syntax was introduced in QEMU-0.12.

Version 2 changes:
- -smp argument build split into a separate function
- always add ",sockets=S,cores=C,threads=T" to -smp if qemu supports it
- use qemuParseCommandLineKeywords for command line parsing

Version 3 changes:
- ADD_ARG_LIT => ADD_ARG and line reordering in qemudBuildCommandLine

* src/qemu/qemu_conf.h: Remove qemuDomainObjPrivate definition
* src/qemu/qemu_driver.c: Add qemuDomainObjPrivate definition.
  Pass qemuMonitorPtr into all monitor APIs instead of the
  virDomainObjPtr instance.
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add thin
  wrappers for all qemuMonitorXXX command APIs, calling into
  qemu_monitor_text.c/h
* src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h:
  Rename qemuMonitor -> qemuMonitorText & update to accept
  qemuMonitorPtr instead of virDomainObjPtr

1cfd5a00eb Make use of private data structure for monitor state
Introduce a new qemuDomainObjPrivate object which is used to store
the private QEMU specific data associated with each virDomainObjPtr
instance. This contains a single member, an instance of the new
qemuMonitorPtr object which encapsulates the QEMU monitor state.
The internals of the latter are private to the qemu_monitor* files,
not to be shown to qemu_driver.c

* src/qemu/qemu_conf.h: Definition of qemuDomainObjPrivate.
* src/qemu/qemu_driver.c: Register a functions for creating
  and freeing qemuDomainObjPrivate instances with the domain
  capabilities. Remove the qemudDispatchVMEvent() watch since
  I/O watches are now handled by the monitor code itself. Pass
  a new qemuHandleMonitorEOF() callback into qemuMonitorOpen
  to allow notification when the monitor quits.
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Introduce
  the 'qemuMonitor' object. Temporarily add new APIs
  qemuMonitorWrite, qemuMonitorRead, qemuMonitorWaitForInput
  to allow text based monitor impl to perform I/O.
* src/qemu/qemu_monitor_text.c: Call APIs for reading/writing
  to monitor instead of accessing the file handle directly.

* src/qemu/qemu.conf src/qemu/qemu_conf.c src/qemu/qemu_conf.h: there is
  a new config type option for mac filtering
* src/qemu/qemu_bridge_filter.[ch]: new module for the ebtable entry points
* src/qemu/qemu_driver.c: plug the MAC filtering at the right places
  in the domain life cycle
* src/Makefile.am po/POTFILES.in: add the new module

  args, and remove hardcoded 'nic' prefix. Leave it upto callers
  instead
* src/qemu/qemu_driver.c: Switch over to using the new
  qemuMonitorAddPCINetwork() method for NIC hotplug
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add new
  qemuMonitorAddPCINetwork API for PCI network device hotplug

b81a7ece97 Fix handling of Xen(ner) detection
Latest upstream QEMU can be built with Xen support, which introduces
a -xen-domid argument. This was  mistakenly detected as -domid due
to old Xenner support. Adapt to cope with both syntax. Also only
set domid if the virt type is xen, or the guest type is xen

* src/qemu_conf.c, src/qemu_conf.h: Detect new -xen-domid flag in
  preference to -domid.
* tests/qemuxml2argvdata/qemuxml2argv-bootloader.args,
  tests/qemuxml2argvdata/qemuxml2argv-input-xen.args: Add missing
  -domid param
* tests/qemuxml2argvdata/qemuxml2argv-misc-uuid.args: Remove bogus
  -boot param.
* tests/qemuxml2argvtest.c: Add missing QEMUD_CMD_FLAG_DOMID params
