994e7567b6 maint: kill all remaining uses of old DEBUG macro
Done mechanically with:
$ git grep -l '\bDEBUG0\? *(' | xargs -L1 sed -i 's/\bDEBUG0\? *(/VIR_&/'

followed by manual deletion of qemudDebug in daemon/libvirtd.c, along
with a single 'make syntax-check' fallout in the same file, and the
actual deletion in src/util/logging.h.

* src/util/logging.h (DEBUG, DEBUG0): Delete.
* daemon/libvirtd.h (qemudDebug): Likewise.
* global: Change remaining clients over to VIR_DEBUG counterpart.

d9ad8ac392 Add VIR_DIV_UP to divide memory or storage request sizes with round up
Use it in all places where a memory or storage request size is converted
to a larger granularity. This avoids requesting too small memory or storage
sizes that could result from the truncation done by a simple division.

This extends the round up fix in 6002e0406c
to the whole codebase.

Instead of reporting errors for odd values in the VMX code round them up.

Update the QEMU Argv tests accordingly as the original memory size 219200
isn't a even multiple of 1024 and is rounded up to 215 megabyte now. Change
it to 219100 and 219136. Use two different values intentionally to make
sure that rounding up works.

Update virsh.pod accordingly, as rounding down and rejecting are replaced
by rounding up.

094c6f4a24 Fix 'make check' after commit 04197350
I broke 'make check' with commit 04197350 by unconditionally
emitting 'hap=' in xen xm driver.  Only emit 'hap=' if
xendConfigVersion >= 3.  I've tested sending 'hap=' to a Xen 3.2
machine without support for hap setting and verified that xend
silently drops the unrecognized setting.

041973504f Add support for HAP feature to xen drivers
xen-unstable c/s 16931 introduced a per-domain setting for hvm
guests to enable/disable hardware assisted paging.  If disabled,
software techniques such as shadow page tables are used.  If enabled,
and the feature exists in underlying hardware, hardware support for
paging is used.

This provides implementation for mapping HAP setting to/from
domxml/native formats in xen drivers.

0fab10e5ed vcpu: improve vcpu support in xen command line
This patch series focuses on xendConfigVersion 2 (xm_internal) and 3

See this link for more details about vcpu_avail for xm usage.

Although this patch adds a distinction between maximum vcpus and

ad4cb9056a xen: Fix bogus error when attaching a device
The xm internal xen driver only supports disk and network devices to be
added to a guest. On an attempt to attach any other device the xm driver
used VIR_ERR_XML_ERROR which resulted in a completely bogus error
message:

error: Failed to attach device from pci.xml

b9c10268e1 Add actions to virDomainLifecycle enum
Xen supports on_crash actions coredump-{destroy,restart}.  libvirt
cannot parse config returned by xend that contains either of these
actions

xen52 # xm li -l test | grep on_crash
    (on_crash coredump-restart)
xen52 # virsh dumpxml test
error: internal error unknown lifecycle type coredump-restart

This patch adds a new virDomainLifecycleCrash enum and appends
the new options to existing destroy, restart, preserve, and
rename-restart options.

ab8b2bea47 bootloader_args is named bootargs in xen-xm
According to <xen-3.4.3/tools/python/xen/xm/create.py:158>
	gopts.var('bootargs', val='NAME',
			  fn=set_value, default=None,
			  use="Arguments to pass to boot loader")
the "bootloader_args" parameter needs to be translated into "bootargs"
when using "virsh domxml-to-native xen-xm".
The reverse direction (domxml-from-native) is already okay.

This patch fixes domxml-to-native and adds two test files to catch this
problem.

6b24755235 domain conf: Track <console> target type
All <console> devices now export a <target> type attribute. QEMU defaults
to 'serial', UML defaults to 'uml, xen can be either 'serial' or 'xen'
depending on fullvirt. Understandably there is lots of test fallout.

This will be used to differentiate between a serial vs. virtio console for
QEMU.

50147933a5 domain conf: Rename character prop targetType -> deviceType
There is actually a difference between the character device type (serial,
parallel, channel, ...) and the target type (virtio, guestfwd). Currently
they are awkwardly conflated.

Start to pull them apart by renaming targetType -> deviceType. This is
an entirely mechanical change.

dddad4bcb4 Support for interface model='netfront'
Xen HVM guests with PV drivers end up with two network interfaces for
each configured interface. One of them being emulated by qemu and the
other one paravirtual. As this might not be desirable, the attached
patch provides a way for users to specify that only paravirtual network
interface should be presented to the guest.

The configuration was inspired by qemu/kvm driver, for which users can
specify model='virtio' to use paravirtual network interface.

The patch adds support for model='netfront' which results in
type=netfront instead of type=ioemu (or nothing for newer xen versions)
in guests native configuration. Xen's qemu ignores interfaces with
type != ioemu and only paravirtual network device will be seen in the
guest.

Four possible configuration scenarios follow:

- no model specified in domain's XML
    - libvirt will behave like before this change; it will set
      type=ioemu for HVM guests on xen host which is not newer than
      XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU
    - covered by existing tests

- PV guest, any model
    - no functional change, model is passed as is (and ignored by the
      hypervisor)
    - covered by existing tests (e.g., *-net-e1000.*)
- HVM guest, model=netfront
    - type is set to "netfront", model is not specified
    - covered by new *-net-netfront.* tests

- HVM guest, model != netfront
    - type is set to "ioemu", model is passed as is
    - covered by new *-net-ioemu.* tests

The fourth scenario feels like a regression for xen newer than
XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU as users who had a model specified
in their guest's configuration won't see a paravirtual interface in
their guests any more. On the other hand, the reason for specifying a
model is most likely the fact that they want to use such model which
implies emulated interface. Users of older xen won't be affected at all
as their xen provides paravirtual interface regardless of the type used.

- src/xen/xm_internal.c: add netfront support for the XM serialization too

e7c78b0a94 Support QEMU's virtual FAT block device driver
Introduce a new type="dir"  mode for <disks> that allows use of
QEMU's  virtual FAT block device driver. eg

    <disk type='dir' device='floppy'>
      <source dir='/tmp/test'/>
      <target dev='fda' bus='fdc'/>
      <readonly/>
    </disk>

gets turned into

  -drive file=fat:floppy:/tmp/test,if=floppy,index=0

Only read-only disks are supported with virtual FAT mode

776b675861 504262 Check for duplicated UUID in XM Xen defines
* src/xen/xm_internal.c: the XM driver was not checking for previously
  defined UUID on new defines. Similar to virDomainObjIsDuplicate()
  behaviour.

89d549c3eb Allow character devices to have different target types
A character device's target (it's interface in the guest) had only a
single property: port. This patch is in preparation for adding targets
which require other properties.
Since this changes the conf type for character devices this affects
a number of drivers:

* src/conf/domain_conf.[ch] src/esx/esx_vmx.c src/qemu/qemu_conf.c
  src/qemu/qemu_driver.c src/uml/uml_conf.c src/uml/uml_driver.c
  src/vbox/vbox_tmpl.c src/xen/xend_internal.c src/xen/xm_internal.c:
  target properties are moved into a union in virDomainChrDef, and a
  targetType field is added to identify which union member should be
  used. All current code which touches a virDomainChrDef is updated both
  to use the new union field, and to populate targetType if necessary.

46992453b9 Annotate many methods with ATTRIBUTE_RETURN_CHECK & fix problems
Nearly all of the methods in src/util/util.h have error codes that
must be checked by the caller to correct detect & report failure.
Add ATTRIBUTE_RETURN_CHECK to ensure compile time validation of
this

* daemon/libvirtd.c: Add explicit check on return value of virAsprintf
* src/conf/domain_conf.c: Add missing check on virParseMacAddr return
  value status & report error
* src/network/bridge_driver.c: Add missing OOM check on virAsprintf
  and report error
* src/qemu/qemu_conf.c: Add missing check on virParseMacAddr return
  value status & report error
* src/security/security_selinux.c: Remove call to virRandomInitialize
  that's done in libvirt.c already
* src/storage/storage_backend_logical.c: Add check & log on virRun
  return status
* src/util/util.c: Add missing checks on virAsprintf/Run status
* src/util/util.h: Annotate all methods with ATTRIBUTE_RETURN_CHECK
  if they return an error status code
* src/vbox/vbox_tmpl.c: Add missing check on virParseMacAddr
* src/xen/xm_internal.c: Add missing checks on virAsprintf
* tests/qemuargv2xmltest.c: Remove bogus call to virRandomInitialize()

cf577653dc Remove bogus const annotations to hash iterator
Most of the hash iterators need to modify either payload of
data args. The const annotation prevents this.

* src/util/hash.h, src/util/hash.c: Remove const-ness from
  virHashForEach/Iterator
* src/xen/xm_internal.c: Remove bogus casts

73c901a807 Take domain type into account when looking up default machine
If one has e.g.

  <guest>
    <os_type>hvm</os_type>
    <arch name='x86_64'>
      <wordsize>64</wordsize>
      <emulator>/usr/bin/qemu-system-x86_64</emulator>
      <machine>pc-0.11</machine>
      <machine canonical='pc-0.11'>pc</machine>
      <machine>pc-0.10</machine>
      <machine>isapc</machine>
      <domain type='qemu'>
      </domain>
      <domain type='kvm'>
        <emulator>/usr/bin/kvm</emulator>
        <machine>pc</machine>
        <machine>isapc</machine>
      </domain>
    </arch>
  </guest>

and start a guest with:

  <domain type='kvm'>
    ...
    <os>
      <type arch='x86_64'>hvm</type>
      ...
    </os>
  </domain>

then the default machine type should be 'pc' and not 'pc-0.11'

Issue was reported by Anton Protopopov.

* src/capabilities.[ch]: pass the domain type to
  virCapabilitiesDefaultGuestArch() and use it to look up the default
  machine type from a specific guest domain if needed.

* src/conf/domain_conf.c, src/xen/xm_internal.c: update

* tests/qemuxml2argvdata/qemuxml2argv-machine-aliases2.xml: update
  the domain type to 'kvm' and remove the machine type to check
  that the default gets looked up correctly
