This follows the same pattern when v8 and v9 were added. I've tested
this with my ESX 5.5 and seems to work fine.

Using any of these chars [:*?"<>|] in a filename is forbidden on
Windows and breaks git operations on Windows as git is not able
to create those files/directories on clone or pull.

Because some of them can be used in UNIX filenames they tend to
creep into filenames; especially : in PCI/SCSI device names that
are used as filenames in test cases.

Windows doesn't allow : in filenames.

Commit 6fdece9a added files with a : in
their names. This broke git operations on Windows as git is not able to
create those files on clone or pull.

Replace : with - in the offending filenames and adapt the test case.
As the tested Linux specific code expects the files to exist with : in
their path use symlinks to provide the name that way.

virNodeDeviceListCaps will always return empty for a pci nodedevice,
actually it should return 'pci'.

It is because the loop variable ncaps isn't increased.

At this point unittest covers 4 basic cases:

 - minimal working XML for bhyve
 - same as above, but with virtio disk
 - ACPI and APIC args test
 - MAC address test

To ease mocking for bhyve unit tests move virBhyveTapGetRealDeviceName()
out of bhyve_command.c to virnetdevtap and rename it to
virNetDevTapGetRealDeviceName().

A patch submitted by Steven Malin last week pointed out a problem with
libvirt's DNS SRV record configuration:

  https://www.redhat.com/archives/libvir-list/2014-March/msg00536.html

When searching for that message later, I found another series that had
been posted by Guannan Ren back in 2012 that somehow slipped between
the cracks:

  https://www.redhat.com/archives/libvir-list/2012-July/msg00236.html

That patch was very much out of date, but also pointed out some real
problems.

This patch fixes all the noted problems by refactoring
virNetworkDNSSrvDefParseXML() and networkDnsmasqConfContents(), then
verifies those fixes by added several new records to the test case.

Problems fixed:

* both service and protocol now have an underscore ("_") prepended on
  the commandline, as required by RFC2782.

  <srv service='sip' protocol='udp' domain='example.com'
       target='tests.example.com' port='5060' priority='10'
       weight='150'/>

  before: srv-host=sip.udp.example.com,tests.example.com,5060,10,150
  after:  srv-host=_sip._udp.example.com,tests.example.com,5060,10,150

* if "domain" wasn't specified in the <srv> element, the extra
  trailing "." will no longer be added to the dnsmasq commandline.

  <srv service='sip' protocol='udp' target='tests.example.com'
       port='5060' priority='10' weight='150'/>

  before: srv-host=sip.udp.,tests.example.com,5060,10,150
  after:  srv-host=_sip._udp,tests.example.com,5060,10,150

* when optional attributes aren't specified, the separating comma is
  also now not placed on the dnsmasq commandline. If optional
  attributes in the middle of the line are not specified, they are
  replaced with a default value in the commandline (1 for port, 0 for
  priority and weight).

  <srv service='sip' protocol='udp' target='tests.example.com'
       port='5060'/>

  before: srv-host=sip.udp.,tests.example.com,5060,,
  after:  srv-host=_sip._udp,tests.example.com,5060

  (actually the would have generated an error, because "optional"
  attributes weren't really optional.)

* The allowed characters for both service and protocol are now limited
  to alphanumerics, plus a few special characters that are found in
  existing names in /etc/services and /etc/protocols. (One exception
  is that both of these files contain names with an embedded ".", but
  "."  can't be used in these fields of an SRV record because it is
  used as a field separator and there is no method to escape a "."
  into a field.) (Previously only the strings "tcp" and "udp" were
  allowed for protocol, but this restriction has been removed, since
  RFC2782 specifically says that it isn't limited to those, and that
  anyway it is case insensitive.)

* the "domain" attribute is no longer required in order to recognize
  the port, priority, and weight attributes during parsing. Only
  "target" is required for this.

* if "target" isn't specified, port, priority, and weight are not
  allowed (since they are meaningless - an empty target means "this
  service is *not available* for this domain").

* port, priority, and weight are now truly optional, as the comments
  originally suggested, but which was not actually true.

Instead of adding one to the iterator on every use.

If there are more than two regexes, but only one of them matches,
the matched groups would be leaked.

Do not check for border iterator values inside the loop,
move the code before/after the loop instead.

It is used to break out of the loop early if one regex does not match.
Use the 'break' statement instead.

In all other drivers we are doing so. Moreover, we don't want to parse
runtime information in attach (even if the attach is meant as live)
because we are generating the runtime info ourselves. We can't trust
users they supply sane values anyway.

When doing live attach, we are passing the inactive definition anyway
since we are passing the result of virDomainDeviceDefCopy() which does
inactive copy by default.

Moreover, we are doing the same mistake in qemuhotplugtest.

Just a side note - it makes perfect sense to parse the runtime info
like alias in qemuDomainDetachDevice and qemuDomainUpdateDeviceFlags()
as in some cases the only difference to distinguish two devices can be
just their alias.

The test is loosely inspired from qemucapabilitiestest
and qemuxml2xmltest.

Added a new test instead of extending an existing one because
the feature being tested don't really fits nicely in any
existing place.

This patch decouples the binary and the capabilities detection
from the guest initialization.

The purpose is to make testing easier.

This patch adds an element to QEMU's capability XML, to
show if the underlying QEMU binary supports the live disk
snapshotting or not.
This allows any client to know ahead of time if the feature
is available.

Without this information available, the only way to check
for the snapshot support is to request one and check for
errors.

Currently, the Linux kernel treats values of '0' and '1' as
the minimum of 2. Values larger than the maximum are changed
to the maximum.

Re-reading the shares value after setting it reflects this in
the live domain XML.

Currently, <cputune><shares>0</shares></cputune> is treated
as if it were not specified.

Treat is as a valid value if it was explicitly specified
and write it to the cgroups.

On error the lofd would have been leaked.

Recent changes in the module seemed to have caused Coverity to reanalyze
certain parts of the code. Previously the code was modified via commit
id '11a11812' to resolve a different error (perhaps DEADCODE).  Up through
commit id '7b3f1f8c' there were no issues.

The new error indicats the 'outbuf' was checked for NULL and then complains
because of the dereference. Adding checks for non-NULL prior to the deref
resulted in a DEADCODE message.

So, resolve using an sa_assert() to keep Coverity quiet especially since
it doesn't understand that outbuf will change as a result of a successful
virCommandRun() call.

Recent changes to the module seemed to have caused Coverity to find a new
issue regarding the failure to check the return from a sendmsg. The code
doesn't seem to care about the return status, so just added an ignore_value
to keep Coverity quiet.

qemuDomainSetSchedulerParametersFlags() calls virQEMUDriverGetConfig() twice
and makes the reference counter leak. This removes redundant call.

We use virBhyveTapGetRealDeviceName() to map network interface name
to a real device path, trying to open possible devices and getting
names by ioctl.

Make it skip devices that fail to open with EBUSY because they're
most likely already used by other VMs.

Commit d9f19c30 moved a lot of the
configuration setup into libxlDriverConfigNew().
However that tries to create the libxl/libxl-driver.log before the
libxl directory gets created in libxlStateInitialize().

This causes the daemon to fail on systems that have not had the directory
created before.

Move the code to create the libxl directory into libxlDriverConfigNew().
