05b9b8fda3 Add volume encryption information handling.
Define an <encryption> tag specifying volume encryption format and
format-depenedent parameters (e.g. passphrase, cipher name, key
length, key).

Currently the only defined parameter is a reference to a "secret"
(passphrase/key) managed using the virSecret* API.

Only the qcow/qcow2 encryption format, and a "default" format used to
let libvirt choose the format during volume creation, is currently
supported.

This patch does not add any users; the <encryption> tag is added in
the following patches to both volumes (to support encrypted volume
creation) and domains.

* docs/*.html: Re-generate
* docs/formatstorageencryption.html.in, docs/sitemap.html.in:
  Add page describing storage encryption data format
* docs/schemas/Makefile.am, docs/schemas/storageencryption.rng:
  Add RNG schema for storage encryption format

* src/storage_encryption_conf.h, src/storage_encryption_conf.c: Internal

78675b228b Simplify PCI hostdev prepare/re-attach using a pciDeviceList type
The qemuPrepareHostDevices() and qemuDomainReAttachHostDevices()
functions are clutter with a bunch of calls to pciGetDevice() and
pciFreeDevice() obscuring the basic logic.

Add a pciDeviceList type and add a qemuGetPciHostDeviceList() function
to build a list from a domain definition. Use this in prepare/re-attach
fto simplify things and eliminate the multiple pciGetDevice calls.

This is especially useful because in the next patch we need to iterate
the hostdevs list a third time and we also need a list type for keeping
track of active devices.

* src/pci.[ch]: add pciDeviceList type and also a per-device 'managed'
  property

* src/libvirt_private.syms: export the new functions

* src/qemu_driver.c: add qemuGetPciHostDeviceList() and re-write
  qemuPrepareHostDevices() and qemuDomainReAttachHostDevices() to use it

4954e079c8 Revert changes to allow pciResetDevice() reset multiple devices
It turns out that the previous attempt at this doesn't work well
in the case of hotplug. We need qemuCheckPciHostDevice() to
disallow the reset affecting devices already attach to the guest,
but we still need to avoid double locking the virDomainObjPtr.

This is all getting messy, I've a better idea.

This reverts commit 6318808270 and
c106c8a18c.

* src/qemu_driver.c, src/pci.[ch], src/xen_unified.c,
  src/libvirt_private.syms: revert a bunch of stuff.

c106c8a18c Check active domain hostdevs before allowing PCI reset
If a PCI device reset causes other devices to be reset, allow it so long
as those other devices are note assigned to another active domain.

Note, we need to take the driver lock qemudNodeDeviceReset() because the
check function will iterate over the domain list.

* src/qemu_conf.c: add qemuCheckPciHostDevice() to iterate over active
  domains checking whether the affected device is assigned

* src/pci.[ch]: add pciDeviceEquals() helper

7636ef4630 Re-factor hostdev hotplug
Re-factor the hostdev hotplug code so that we can easily add PCI
hostdev hotplug to qemudDomainAttachHostDevice().

* src/qemu_driver.c: rename qemudDomainAttachHostDevice() to
  qemudDomainAttachHostUsbDevice(); make qemudDomainAttachHostDevice()
  handle all hostdev types

* src/libvirt_private.syms: export a couple of hostdev related
  ToString() functions

9147bf2a73 Several fixes to libvirtd's log setup
* qemud/qemud.c src/logging.[ch]: Similar as for general libvirt, don't
  convert high priority levels to debug level. Ignore LIBVIRT_LOG_FILTERS
  and LIBVIRT_LOG_OUTPUTS when they're set to the empty string, otherwise
  they can override a valid setting from the config file. Send all
  settings through the parser functions for validation, so that the
  existence of a bad setting doesn't nullify a good setting that should
  have applied -- particularly the default output. Keep the order of
  precedence consistent for all variables between the environment and
  the config file.  Warn when an invalid log level, filter, or output
  is ignored.
* src/libvirt_private.syms: export internally a few convenience functions

38fd207e53 Add virCapsGuestMachine structure
A subsequent commit will add a "canonical" field to this structure,
this patch basically just prepares the way for that.

The new type is added, along with virCapabilitiesAlloc/FreeMachines()
helpers and a whole bunch of code to make the transition.

One quirk is that virCapabilitiesAddGuestDomain() and
virCapabilitiesAddGuest() take ownership of the machine list rather
than duping it. This makes sense to avoid needless copying.

* src/capabilities.h: add the virCapsGuestMachine struct and use it
  in virCapsGuestDomainInfo, add prototypes for new functions and
  update the AddGuest() prototypes

* src/capabilities.c: add code for allocating and freeing the new
  type, change the machines parameter to AddGuest() etc.

* src/libvirt_private.syms: export the new helpers

* src/qemu_conf.c: update all the machine type code to use the new
  struct

* src/xen_internal.c: ditto

* tests/testutilsqemu.c: ditto

946c489c68 Refactor cgroups to allow a group per driver to be managed directly
Allow the driver level cgroup to be managed explicitly by the
hypervisor drivers, in order to detect whether to enable or
disable cgroup support for domains. Provides better error
reporting of failures. Also allow for creation of cgroups for
unprivileged drivers if controller is accessible by the user.

35153940e3 Basic qemu NIC hotplug support
Implement basic NIC hotplug support using the 'host_net_add' and
'pci_add' qemu monitor commands.

For now, we don't support 'bridge' or 'network' types.

Also, if pci_add fails, we currently fail to remove the backend
which we added.

Finally, NIC hot-unplug support is missing.

* src/qemu_driver.c: add qemudDomainAttachNetDevice()

* src/qemu_conf.[ch]: export qemuBuildNicStr(), qemuBuildHostNetStr()
  and qemuAssignNames()

* src/libvirt_private.syms: export virDomainNetTypeToString()

3f305eb1e9 Refactor storage XML parsing to be consistent with domain/network conf.
The storage driver arranges its parsing routines in a way that make them
difficult to use in the test driver for non-default file parsing. This
refactoring moves things to be consistent with the way domain_conf and
network_conf do things.

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:

3f63c44d12 Add virCapabilities*EmulatorRequired.
Certain drivers always need an 'emulator' specified in the XML (qemu and lxc
at least). Store this info in capabilities.

We will eventually use this to move default emulator handling out of
drivers and into domain_conf.*
