those switches to the 'net-list' command. We should. They are
merely copied over from 'list' command.

Move all the system_* fields into a separate struct. Not only this
simplifies the code a bit it also helps us to identify whether BIOS
info is present. We don't have to check all the four variables for
being not-NULL, but we can just check the pointer to the struct.

Fairly recently we've introduced virnetservertest. This test has some

not distributed among with the test. Therefore 'make distcheck'
failed. Fix this by adding the directory into EXTRA_DIST.

This patch adds the support of queues attribute of the driver element
for vhost-user interface type. Example:

      <source type='unix' path='/tmp/vhost2.sock' mode='client'/>
      <model type='virtio'/>
      <driver queues='4'/>

The support for this was added in QEMU with commit
830d70db692e374b55555f4407f96a1ceefdcc97.  Unfortunately we have to do
another ugly version-based capability check.  The other option would be
not to check for the capability at all and leave that to qemu as it's
done with multiqueue tap devices.

Store the cpu count in an intermediate variable and reuse it rather than
caluclating the index.

Additionally add a coverity silencing comment.

If a macro has a string value, the @string attribute will contain the
value. Otherwise @string attribute will be missing.

For example, the following macro definition from libvirt-domain.h:

 /**
  * VIR_MIGRATE_PARAM_URI:
  * ...
  */
 # define VIR_MIGRATE_PARAM_URI               "migrate_uri"

will result in

 <macro name='VIR_MIGRATE_PARAM_URI' file='libvirt-domain' string='migrate_uri'>
   <info><![CDATA[...]]></info>
 </macro>

The virNetServer class has the ability to serialize its state
to a JSON file, and then re-load that data after an in-place
execve() call to re-connect to active file handles. This data
format is critical ABI that must have compatibility across
releases, so it should be tested...

The socket test suite has a function for checking if IPv4
or IPv6 are available, and returning a free socket. The
first bit of that will be needed in another test, so pull
that logic out into a separate helper method.
Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

By default, getaddrinfo() will return addresses for both
IPv4 and IPv6 if both protocols are enabled, and so the
RPC code will listen/connect to both protocols too. There
may be cases where it is desirable to restrict this to
just one of the two protocols, so add an 'int family'
parameter to all the TCP related APIs.

The function takes two important arguments (among many others): @node
and @page_size. From these two a path under /sys is constructed. The
path is then used to read and write the desired size of huge pages
pool. However, if the path does not exists due to either @node or
@page_size having nonexistent value (e.g. there's no such NUMA node or
no page size like -2), an cryptic error message is produced:

  virsh # allocpages --pagesize 2049 --pagecount 8 --cellno -2
  error: Failed to open file '/sys/devices/system/node/node-2/hugepages/hugepages-2049kB/nr_hugepages': No such file or directory

Add two more checks to catch this and therefore produce much more
friendlier error messages.

Statistics provided through PCS SDK. As we have only async interface in SDK we
need to be subscribed to statistics in order to get it. Trivial solution on
every stat request to subscribe, wait event and then unsubscribe will lead to
significant delays in case of a number of successive requests, as the event
will be delivered on next PCS server notify cycle. On the other hand we don't
want to keep unnesessary subscribtion. So we take an hibrid solution to
subcsribe on first request and then keep a subscription while requests are
active. We populate cache of statistics on subscribtion events and use this
cache to serve libvirts requests.

 * Cache details.
Cache is just handle to last arrived event, we call this cache
as if this handle is valid it is used to serve synchronous
statistics requests. We use number of successive events count
to detect that user lost interest to statistics. We reset this
count to 0 on every request. If more than PARALLELS_STATISTICS_DROP_COUNT
successive events arrive we unsubscribe. Special value of -1
of this counter is used to differentiate between subscribed/unsubscribed state
to protect from delayed events.

Values of PARALLELS_STATISTICS_DROP_COUNT and PARALLELS_STATISTICS_TIMEOUT are
just drop-ins, choosen without special consideration.

 * Thread safety issues
Use parallelsDomObjFromDomainRef in parallelsDomainBlockStats as
we could wait on domain lock down on stack in prlsdkGetStatsParam
and if we won't keep reference we could get dangling pointer
on return from wait.

We need to use qemu-system-aarch64 to run armv7l KVM VMs on an aarch64
host.

And it always has, so advertise it similarly to i686

qemu 2.3.0 added the -cpu host,aarch64=off option, which allows using
qemu-system-aarch64 KVM to run armv7l VMs.

Add a capabilities check for it, wire it up in qemu_command, and test
the command line generation.

2 reasons to to this.
1. PCS SDK really don't care of handler return value.
2. It hard to imagine how notifier can handle
subscriber failures. Even if there are some situations
we probably will use some special error codes and
not just throw error codes we get from SDK itself.

Use issuer type instead of event type to group
vm related events. This saves us from
explicit enumeration of all vm event types in
prlsdkHandleVmEvent.

Not every architecture out there has 'char' signed by default.
For instance, my arm box has it unsigned by default:

  $ gcc -dM -E - < /dev/null | grep __CHAR_UNSIGNED__
  #define __CHAR_UNSIGNED__ 1

Therefore, after 65c61e50 the test if failing for me. Problem is,
we are trying to assign couple of negative values into char
assuming some will overflow and some don't. That can't be the
case if 'char' is unsigned by default. Lets use more explicit types
instead: int8_t and uint8_t where is no ambiguity.

The stubs for the two functions that are compiled on platforms that
don't have HAVE_GETPWUID_R and friends defined do not return error but
report an error message. The calling code then assumes that the @uid or
@gid arguments were filled, which is not the case in the stubs.
