d70f2e117a numad: Always output 'placement' of <vcpu>
<vcpu> is not an optional node. The value for its 'placement'
actually always defaults to 'static' in the underlying codes.
(Even no 'cpuset' and 'placement' is specified, the domain
process will be pinned to all the available pCPUs).

11ec6bd891 Xen: Fix <clock> handling
XenD-3.1 introduced managed domains. HV-domains have rtc_timeoffset
(hgd24f37b31030 from 2007-04-03), which tracks the offset between the
hypervisors clock and the domains RTC, and is persisted by XenD.
In combination with localtime=1 this had a bug until XenD-3.4
(hg5d701be7c37b from 2009-04-01) (I'm not 100% sure how that bug
manifests, but at least for me in TZ=Europe/Berlin I see the previous
offset relative to utc being applied to localtime again, which manifests
in an extra hour being added)

XenD implements the following variants for clock/@offset:
- PV domains don't have a RTC → 'localtime' | 'utc'
- <3.1: no managed domains → 'localtime' | 'utc'
- ≥3.1: the offset is tracked for HV → 'variable'
        due to the localtime=1 bug → 'localtime' | 'utc'
- ≥3.4: the offset is tracked for HV → 'variable'

Current libvirtd still thinks XenD only implements <clock offset='utc'/>
and <clock offset='localtime'/>, which is wrong, since the semantic of
'utc' and 'localtime' specifies, that the offset will be reset on
domain-restart, while with 'variable' the offset is kept. (keeping the
offset over "virsh edit" is important, since otherwise the clock might
jump, which confuses certain guest OSs)

xendConfigVersion was last incremented to 4 by the xen-folks for
xen-3.1.0. I know of no way to reliably detect the version of XenD
(user space tools), which may be different from the version of the
hypervisor (kernel) version! Because of this only the change from
'utc'/'localtime' to 'variable' in XenD-3.1 is handled, not the buggy
behaviour of XenD-3.1 until XenD-3.4.

For backward compatibility with previous versions of libvirt Xen-HV
still accepts 'utc' and 'localtime', but they are returned as 'variable'
on the next read-back from Xend to libvirt, since this is what XenD
implements: The RTC is NOT reset back to the specified time on next
restart, but the previous offset is kept.
This behaviour can be turned off by adding the additional attribute
adjustment='reset', in which case libvirt will report an error instead
of doing the conversion. The attribute can also be used as a shortcut to
offset='variable' with basis='...'.

With these changes, it is also necessary to adjust the xen tests:

"localtime = 0" is always inserted, because otherwise on updates the
value is not changed within XenD.

adjustment='reset' is inserted for all cases, since they're all <
XEND_CONFIG_VERSION_3_1_0, only 3.1 introduced persistent
rtc_timeoffset.

Some statements change their order because code was moved around.

265457845f xml: output memory unit for clarity
Make it obvious to 'dumpxml' readers what unit we are using,
since our default of KiB for memory (1024) differs from qemu's
default of MiB; and differs from our use of bytes for storage.

Tests were updated via:

$ find tests/*data tests/*out -name '*.xml' | \
  xargs sed -i 's/<\(memory\|currentMemory\|hard_limit\|soft_limit\|min_guarantee\|swap_hard_limit\)>/<\1 unit='"'KiB'>/"
$ find tests/*data tests/*out -name '*.xml' | \
  xargs sed -i 's/<\(capacity\|allocation\|available\)>/<\1 unit='"'bytes'>/"

followed by a few fixes for the stragglers.

Note that with this patch, the RNG for <memory> still forbids
validation of anything except unit='KiB', since the code silently
ignores the attribute; a later patch will expand <memory> to allow
scaled input in the code and update the RNG to match.

ef79fb5b5f conf: add <listen> subelement to domain <graphics> element
Once it's plugged in, the <listen> element will be an optional
replacement for the "listen" attribute that graphics elements already
have. If the <listen> element is type='address', it will have an
attribute called 'address' which will contain an IP address or dns
name that the guest's display server should listen on. If, however,
type='network', the <listen> element should have an attribute called
'network' that will be set to the name of a network configuration to
get the IP address from.

* docs/schemas/domain.rng: updated to allow the <listen> element

* docs/formatdomain.html.in: document the <listen> element and its
  attributes.

* src/conf/domain_conf.[hc]:

  1) The domain parser, formatter, and data structure are modified to
     support 0 or more <listen> subelements to each <graphics>
     element. The old style "legacy" listen attribute is also still
     accepted, and will be stored internally just as if it were a
     separate <listen> element. On output (i.e. format), the address
     attribute of the first <listen> element of type 'address' will be
     duplicated in the legacy "listen" attribute of the <graphic>
     element.

  2) The "listenAddr" attribute has been removed from the unions in
     virDomainGRaphicsDef for graphics types vnc, rdp, and spice.
     This attribute is now in the <listen> subelement (aka
     virDomainGraphicsListenDef)

  3) Helper functions were written to provide simple access
     (both Get and Set) to the listen elements and their attributes.

* src/libvirt_private.syms: export the listen helper functions

* src/qemu/qemu_command.c, src/qemu/qemu_hotplug.c,
  src/qemu/qemu_migration.c, src/vbox/vbox_tmpl.c,
  src/vmx/vmx.c, src/xenxs/xen_sxpr.c, src/xenxs/xen_xm.c

  Modify all these files to use the listen helper functions rather
  than directly referencing the (now missing) listenAddr
  attribute. There can be multiple <listen> elements to a single
  <graphics>, but the drivers all currently only support one, so all
  replacements of direct access with a helper function indicate index
  "0".

* tests/* - only 3 of these are new files added explicitly to test the
  new <listen> element. All the others have been modified to reflect
  the fact that any legacy "listen" attributes passed in to the domain
  parse will be saved in a <listen> element (i.e. one of the
  virDomainGraphicsListenDefs), and during the domain format function,
  both the <listen> element as well as the legacy attributes will be
  output.

c1a98d8825 Fix order of disks and controllers
Commit 2d6adabd53 replaced qsorting disk
and controller devices with inserting them at the right position. That
was to fix unnecessary reordering of devices. However, when parsing
domain XML devices are just taken in the order in which they appear in
the XML since. Use the correct insertion algorithm to honor device
target.

e547e44cb0 xen: parse and generate hpet item in sxpr
Recent versions of Xen disable the virtual HPET by default.  This is
usually more precise because tick policies are not implemented for
the HPET in Xen.  However, there may be several reasons to control
the HPET manually: 1) to test the emulation; 2) because distros may
provide the knob while leaving the default to "enabled" for compatibility
reasons.

This patch provides support for the hpet item in both sexpr and xm
formats, and translates it to a <timer> element.

3ee7cf6c9b Add support for multiple serial ports into the Xen driver
this is the patch to add support for multiple serial ports to the
libvirt Xen driver. It support both old style (serial = "pty") and
new style (serial = [ "/dev/ttyS0", "/dev/ttyS1" ]) definition and
tests for xml2sexpr, sexpr2xml and xmconfig have been added as well.

Written and tested on RHEL-5 Xen dom0 and working as designed but
the Xen version have to have patch for RHBZ #614004 but this patch
is for upstream version of libvirt.

Also, this patch is addressing issue described in RHBZ #670789.

0fab10e5ed vcpu: improve vcpu support in xen command line
This patch series focuses on xendConfigVersion 2 (xm_internal) and 3
(xend_internal), but leaves out changes for xenapi drivers.

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

20311a9af8 xen tests: Fix missing "type ioemu" with rhel5-api
The most common cause of errors with rhel5-api turn on was missing
"(type ioemu)" in sexpr or its equivalent in XM configuration file. This
happens because the presence of that part in sexpr (or cfg) depends on
xen version the host is running. Let's avoid it by explicitly specifying
interface model which ensures "type ioemu" will always be emitted.

This patch adds

    <model type='e1000'/>

withing the interface element in all affected xml files. And

    (model 'e1000')

to all corresponding sexpr files with similar fix to cfg files. Such
configuration works regardless on Xen version.

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.
