Rename qemuBuildShmemDevCmd to qemuBuildShmemDevStr and change the

And split the chardev creation part in a new function
qemuBuildShmemBackendStr for reuse in the device hotplug code later.

Since QEMU commit ea96bc6 [1]:
i386: drop FDC in pc-q35-2.4+ if neither it nor floppy drives are wanted
the floppy controller is no longer implicit.

Specify it explicitly on the command line if the machine type version
is 2.4 or later.

Note that libvirt's floppy drives do not result in QEMU implying the
controller, because libvirt uses if=none instead of if=floppy.

For the implicit controller, we set them via -global.
Separating them will allow reuse for explicit fdc controller as well.

No functional impact apart from one extra allocation.

This allows to build libvirt under MinGW

Commit 2a31c5f0 introduced support for storage pool state XMLs, however
it also introduced a regression:

if (!virstoragePoolObjIsActive(pool)) {
    virStoragePoolObjUnlock(pool);
    continue;
}

The idea behind this was that since we've got state XMLs and the pool
wasn't marked as active by autostart routine (if the autostart flag had been
set earlier), the pool is inactive and we can leave it be and continue with
other pools. However, filesystem type pools like fs,dir, possibly netfs are
supposed to be active if the filesystem is mounted on the host. And this is
exactly where the regression occurs, e.g. pool type 'dir' which has been
previously destroyed and marked as !autostart gets filtered out
by the condition above.
The resolution should be simply to remove the condition completely,
all pools will get their 'active' flag updated by check callback and if
they do not support such callback, the logic doesn't change and such
pools will be inactive by default (e.g. RBD, even if a state XML exists).

Optimize the virBitmap to array-of-char bitmap conversion by skipping
trailing zero bytes.

This also fixes a regression when requesting iothread information from a
live VM since after commit 825df8c3 the
bitmap returned from virProcessGetAffinity is too big to be formatted
properly via RPC. A user would get the following error:

error: Unable to get domain IOThreads information
error: Unable to encode message payload

'maxcpu' and 'vcpus' are set but not used after that

When use setvcpus command with --guest option to a offline vm,
we will get error:

 # virsh setvcpus test3 1 --guest
 error: Guest agent is not responding: QEMU guest agent is not connected

However guest is not running, agent status could not be connected.
In this case, report domain is not running will be better than agent is
not connected. Move the guest status check more early to output error to
point out guest status is not right.

Also from the logic, a running vm is a basic requirement to use
agent, we cannot use agent if vm is not running.

PrlVmDevNet_SetAutoApply to makes necessary settings within guest OS
In linux case it creates network startup scripts
/etc/sysconfig/network-scripts/ifcfg-ethN and fills it with necessary
parameters.

There should be at least one domain for each guest
in cababilities. And in current code we don't add
domain for this guest for example.

    if ((guest = virCapabilitiesAddGuest(caps, VIR_DOMAIN_OSTYPE_HVM,
                                         VIR_ARCH_X86_64,

                                         NULL, 0, NULL)) == NULL)

Anyway, with two virt types it looks a litte messy, so let's
move adding guest and domain to a separate function.

Avoid a false positive since Coverity find a path in virResizeN which
could return 0 prior to the allocation of memory and thus flags a
possible NULL dereference. Instead allocate the output buffer based
on 'nparams' and only fill it partially if need be - shouldn't be too
much a waste of space. Quicker than multiple VIR_RESIZE_N calls or
two loops of STREQ's sandwiched around a single VIR_ALLOC_N using
'n' matches from a first loop to generate the 'n' addresses to return

Commit id '81dd81e4' caused a regression when attempting to print a
specific vcpuid that is out of the range of the maximum vcpus for
the guest, such as:

 $ virsh vcpupin $dom 1000

Rather than just recover the old message, let's adjust the message based
on what would be displayed for a similar failure in the set path, such as:

 $ virsh vcpupin $dom 1000
 error: vcpu 1000 is out of range of persistent cpu count 2

 $ virsh vcpupin $dom 1000 --live
 error: vcpu 1000 is out of range of live cpu count 2
