It's funny, but Routed network name was incorrect. We should use
host-routed instead.

Recently, libprlsdk got a separate flag PNA_BRIDGE corresponding to
type=bridge libvirt network interfaces. Let's use it and get rid of
all workarounds previously added to  support it.

We don't support cpu pinning for TCG domains because QEMU runs them in
one thread only.  But vcpupin command was able to set them, which
resulted in a failed startup, so make sure that doesn't happen.

When starting a new domain, we allocate the USB addresses and keep
an address cache in the domain object's private data.

However this data is lost on libvirtd restart.

Also generate the address cache if all the addresses have been
specified, so that devices hotplugged after libvirtd restart
also get theirs assigned.

https://bugzilla.redhat.com/show_bug.cgi?id=1387666

Return 0 instead of 1, so that qemuDomainAttachChrDevice does not
assume the address neeeds to be released on error.

No functional change, since qemuDomainReleaseDeviceAddress has been a noop
for virtio serial addresses since the address cache was removed
in commit 19a148b7.

For domains with no USB address cache, we should not attempt
to generate a USB address.

https://bugzilla.redhat.com/show_bug.cgi?id=1387665

This function should never need a cleanup section.

This time do not require an address cache as a parameter.

Simplify qemuDomainAttachChrDeviceAssignAddr to not generate
the virtio serial address cache for devices of other types.

Partially reverts commit 925fa4b9.

Commit 19a148b7 dropped the cache from QEMU's private domain object.
Assume the callers do not have the cache by default and use
a longer name for the internal ones that do.

This makes the shorter 'virDomainVirtioSerialAddrAutoAssign'
name availabe for a function that will not require the cache.

The 'on_shutdown' was the name in Xen, there was never such option in
libvirt's domain XML.

Since we're using autoconf to substitute the right value in
Makefile.am now, we can use a less generic name without running
into circular dependencies.

Adding $(prefix) in Makefile.am, as we were doing, means that
it would be prepended even when using --with-ws-plugindir,
which is something we don't want to happen.

Instead, we add it beforehand but take care that it doesn't
get expanded until make is called.

Even when we're building $plugindir ourselves because we can't
retrieve it using pkg-config, we still want to strip the prefix,
except in that case it would be the same prefix we're using for
building libvirt.

The fact that $plugindir is missing also doesn't tell us
anything about $ws_prefix, so we have to handle the two variables
separately.

Keep all variable declarations close together.

Use a separate variable instead of setting it inline for
slightly cleaner code.

Support for virtio disks was added in commit id 'fceeeda2', but not for
SCSI drives. Add the secret for the server when hotplugging a SCSI drive.
No need to make any adjustments for unplug since that's handled during
the qemuDomainDetachDiskDevice call to qemuDomainRemoveDiskDevice in
the qemuDomainDetachDeviceDiskLive switch.

Added a test to/for the command line processing to show the command line
options when adding a SCSI drive for the guest.

Complete the implementation of support for TLS encryption on
chardev TCP transports by adding the hotplug ability of a secret
to generate the passwordid for the TLS object for chrdev, RNG,
and redirdev.

Fix up the order of object removal on failure to be the inverse
of the attempted attach (for redirdev, chr, rng) - for each the
tls object was being removed before the chardev backend.

Likewise, add the ability to hot unplug that secret object as well
and be sure the order of unplug matches that inverse order of plug.

Add the secret object so the 'passwordid=' can be added if the command line
if there's a secret defined in/on the host for TCP chardev TLS objects.

Preparation for the secret involves adding the secinfo to the char source
device prior to command line processing. There are multiple possibilities
for TCP chardev source backend usage.

Add test for at least a serial chardev as an example.

Commit id '6e6b4bfc' added the object, but forgot the other end.

Need to remove the drive first, then the secobj and/or encobj if they exist.
This is because the drive has a dependency on secobj (or the secret for
the networked storage server) and/or the encobj (or the secret for the
LUKS encrypted volume).  Deleting either object first leaves an drive
without it's respective objects.

Add in the block I/O throttling length/duration parameter to the command
line if supported. If not supported, fail command creation.

Add the xml2argvtest for testing.

Modify _virDomainBlockIoTuneInfo and rng schema to support the _length
options for bps/iops throttling values. Document the new values.

Add support for a duration/length for the bps/iops and friends.

Modify the API in order to add the "blkdeviotune." specific definitions
for the iotune throttling duration/length options

    total_bytes_sec_max_length
    write_bytes_sec_max_length
    read_bytes_sec_max_length
    total_iops_sec_max_length
    write_iops_sec_max_length
    read_iops_sec_max_length

Add the capability to detect if the qemu binary can support the feature
to use bps-max-length and friends.

Add new options to allow proving a duration/length in seconds to allow the
bps/iops (and friends) to occur:

    total_bytes_sec_max_length
    write_bytes_sec_max_length
    read_bytes_sec_max_length
    total_iops_sec_max_length
    write_iops_sec_max_length
    read_iops_sec_max_length

Add continue for compiler hint to return to for control

Create a helper to set the bytes/iops iotune default values based on
the current qemu setting for both the live and persistent definitions.
NB: This also fixes an unreported bug where the persistent values for
*_max and size_iops_sec would be set back to 0 if unrelated persistent
values were set.

Since persistent_def is the only place that uses it, let's just keep
it closer to where it's used.

This patch will also adjust the qemuMonitorJSONSetBlockIoThrottle error
procession so that rather than returning/displaying:

    "error: internal error: Unexpected error"

Fetch the actual error message from qemu and display that

Create a macros to hide all the comparisons for each of the fields.

Add a 'continue;' for a compiler hint that we only need to find one
this should be similar enough to the if - elseif - elseif logic.

After succesfully reading an outdated caps cache from disk,
calling virQEMUCapsReset did not properly clear out the calculated
host CPU model. This lead to a memory leak when the host CPU model
pointer was overwritten later in virQEMUCapsNewForBinaryInternal.

Introduced by commit 68c70118.

Although the migration port is immediately released in the
finish phase of migration, it was never set in the domain
private object when allocated in the prepare phase. So
libxlDomainMigrationFinish() always released a 0-initialized
migrationPort, leaking any allocated port. After enough
migrations to exhaust the migration port pool, migration would
fail with

error: internal error: Unable to find an unused port in range
       'migration' (49152-49216)

Fix it by setting libxlDomainObjPrivate->migrationPort to the
port allocated in the prepare phase. While at it, also fix
leaking an allocated port if the prepare phase fails.

An upcoming commit will remove the "flag" argument from all the calls
to reserve the next available address|slot, but I don't want to change
the arguments in the hypervisor-agnostic
virDomainPCIAddressReserveNext*() functions, so this patch places a
simple qemu-specific wrapper around those functions - the new
functions don't take a flags arg, but grab it from the device's
info->pciConnectFlags.
