ec63000a62 xenconfig: support vif bandwidth in xm and xl parser and formatter
Both xm and xl config have long supported specifying vif rate
limiting, e.g.

vif = [ 'mac=00:16:3E:74:3d:76,bridge=br0,rate=10MB/s' ]

Add support for mapping rate to and from <bandwidth> in the xenconfig
parser and formatter. rate is mapped to the required 'average' attribute
of the <outbound> element, e.g.

  <interface type='bridge'>
    ...
    <bandwidth>
      <outbound average='10240'/>
    </bandwidth>
  </interface>

Also add a unit test to check the conversion logic.

1dd34bbb4b xenconfig: support vif bandwidth in sexpr parser and formatter
The xen sexpr config format has long supported specifying vif rate
limiting, e.g.

  (device
    (vif
      (mac '00:16:3e:1b:b1:47')
      (rate '10240KB/s')
      ...
    )
  )

Add support for mapping rate to and from <bandwidth> in the xenconfig
sexpr parser and formatter. rate is mapped to the required 'average'
attribute of the <outbound> element, e.g.

  <interface type='bridge'>
    ...
    <bandwidth>
      <outbound average='10240'/>
    </bandwidth>
  </interface>

Also add unit tests to check the conversion logic.

This patch benefits both the old xen driver and the libxl driver.
Both drivers gain support for vif bandwidth when converting to/from
domXML and xen-sxpr. In addition, the old xen driver will now be
able to handle vif 'rate' setting when communicating with xend.

5b74103b0b Xen: support maxvcpus in xm and xl config
From: Ian Campbell <ian.campbell@citrix.com>

xend prior to 4.0 understands vcpus as maxvcpus and vcpu_avail
as a bit map of which cpus are online (default is all).

xend from 4.0 onwards understands maxvcpus as maxvcpus and
vcpus as the number which are online (from 0..N-1). The
upstream commit (68a94cf528e6 "xm: Add maxvcpus support")
claims that if maxvcpus is omitted then the old behaviour
(i.e. obeying vcpu_avail) is retained, but AFAICT it was not,
in this case vcpu==maxcpus==online cpus. This is good for us
because handling anything else would be fiddly.

This patch changes parsing of the virDomainDef maxvcpus and vcpus
entries to use the corresponding 'maxvcpus' and 'vcpus' settings
from xm and xl config. It also drops use of the old Xen 3.x
'vcpu_avail' setting.

The change also removes the maxvcpus limit of MAX_VIRT_VCPUS (since
maxvcpus is simply a count, not a bit mask), which is particularly
crucial on ARM where MAX_VIRT_CPUS == 1 (since all guests are
expected to support vcpu placement, and therefore only the boot
vcpu's info lives in the shared info page).

Existing tests adjusted accordingly, and new tests added for the
'maxvcpus' setting.

5c668a78d8 qemu: add udp interface support
Adds a new interface type using UDP sockets, this seems only applicable
to QEMU but have edited tree-wide to support the new interface type.

The interface type required the addition of a "localaddr" (local
address), this then maps into the following xml and qemu call.

<interface type='udp'>
  <mac address='52:54:00:5c:67:56'/>
  <source address='127.0.0.1' port='11112'>
    <local address='127.0.0.1' port='22222'/>
  </source>
  <model type='virtio'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</interface>

QEMU call:
	-net socket,udp=127.0.0.1:11112,localaddr=127.0.0.1:22222

Notice the xml "local" entry becomes the "localaddr" for the qemu call.

a5b55bd931 xenconfig: fix spice mousemode and copypaste
From xl.cfg950 man page:

spiceagent_mouse=BOOLEAN
Whether SPICE agent is used for client mouse mode. The default is
true (1) (turn on)

spicevdagent=BOOLEAN
Enables spice vdagent. The Spice vdagent is an optional component for
enhancing user experience and performing guest-oriented management
tasks. Its features includes: client mouse mode (no need to grab
mouse by client, no mouse lag), automatic adjustment of screen
resolution, copy and paste (text and image) between client and domU.
It also requires vdagent service installed on domU o.s. to work.
The default is 0.

spice_clipboard_sharing=BOOLEAN
Enables Spice clipboard sharing (copy/paste). It requires spicevdagent
enabled. The default is false (0).

So if spiceagent_mouse is enabled (client mouse mode) or
spice_clipboard_sharing is enabled, spicevdagent must be enabled.
Along with this change, s/spicedvagent/spicevdagent, set
spiceagent_mouse correctly, and add a test for these spice
features.

0fe504f15a xenconfig: don't use "kernel" for hvmloader
In xl config, hvmloader is implied for hvm guests.  It is not
specified with the "kernel" option like xm config.  The "kernel"
option, along with "ramdisk" and "extra", is used for HVM direct
kernel boot.  Instead of using "kernel" option to populate
virDomainDef object's os.loader->path, use hvmloader discovered
when gathering capabilities.

This change required fixing initialization of capabilities in

4f9907cd11 conf: Replace access to def->mem.max_balloon with accessor functions
As there are two possible approaches to define a domain's memory size -
one used with legacy, non-NUMA VMs configured in the <memory> element
and per-node based approach on NUMA machines - the user needs to make
sure that both are specified correctly in the NUMA case.

To avoid this burden on the user I'd like to replace the NUMA case with
automatic totaling of the memory size. To achieve this I need to replace
direct access to the virDomainMemtune's 'max_balloon' field with
two separate getters depending on the desired size.

The two sizes are needed as:
1) Startup memory size doesn't include memory modules in some
hypervisors.
2) After startup these count as the usable memory size.

Note that the comments for the functions are future aware and document
state that will be present after a few later patches.

4689cdf779 Introduce support for parsing/formatting Xen xl config format
Introduce a parser/formatter for the xl config format.  Since the
deprecation of xm/xend, the VM config file format has diverged as
new features are added to libxl.  This patch adds support for parsing
and formating the xl config format.  It supports the existing xm config
format, plus adds support for spice graphics and xl disk config syntax.

Disk config is specified a bit differently in xl as compared to xm.  In
xl, disk config consists of comma-separated positional parameters and
keyword/value pairs separated by commas. Positional parameters are
specified as follows

   target, format, vdev, access

Supported keys for key=value options are

  devtype, backendtype

The positional paramters can also be specified in key/value form.  For
example the following xl disk config are equivalent

    /dev/vg/guest-volume,,hda
    /dev/vg/guest-volume,raw,hda,rw
    format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume

See $xen_sources/docs/misc/xl-disk-configuration.txt for more details.

xl disk config is parsed with the help of xlu_disk_parse() from
libxlutil, libxl's utility library.  Although the library exists
in all Xen versions supported by the libxl virt driver, only
recently has the corresponding header file been included.  A check
for the header is done in configure.ac.  If not found, xlu_disk_parse()
is declared externally.

2c78051a14 src/xenconfig: Xen-xl parser
Introduce a Xen xl parser

This parser allows for users to convert the new xl disk format and
spice graphics config to libvirt xml format and vice versa. Regarding
the spice graphics config, the code is pretty much straight forward.
For the disk {formating, parsing}, this parser takes care of the new
xl format which include positional parameters and key/value parameters.
In xl format disk config a <diskspec> consists of parameters separated by
commas. If the parameters do not contain an '=' they are automatically
assigned to certain options following the order below

   target, format, vdev, access

The above are the only mandatory parameters in the <diskspec> but there
are many more disk config options. These options can be specified as
key=value pairs. This takes care of the rest of the options such as

  devtype, backend, backendtype, script, direct-io-safe,

The positional paramters can also be specified in key/value form
for example

    /dev/vg/guest-volume,,hda
    /dev/vg/guest-volume,raw,hda,rw
    format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume

are interpleted to one config.

In xm format, the above diskspec would be written as

phy:/dev/vg/guest-volume,hda,w

The disk parser is based on the same parser used successfully by
the Xen project for several years now.  Ian Jackson authored the
scanner, which is used by this commit with mimimal changes.  Only
the PREFIX option is changed, to produce function and file names
more consistent with libvirt's convention.

https://bugzilla.redhat.com/show_bug.cgi?id=1160995

In our config files users are expected to pass several integer values
for different configuration knobs. However, majority of them expect a
nonnegative number and only a few of them accept a negative number too
(notably keepalive_interval in libvirtd.conf).
Therefore, a new type to config value is introduced: VIR_CONF_ULONG
that is set whenever an integer is positive or zero. With this
approach knobs accepting VIR_CONF_LONG should accept VIR_CONF_ULONG
too.
