If the spec file applies a patch which touches any file in the API XMLs
dependency tree, we need to regenerate the XMLs and consequently
recreate hvsupport.html. The file will contain a time stamp in a comment
which means it will be different every time the package is built. The
commit a54c9622 which added the time stamp also added support for
SOURCE_DATE_EPOCH environment variable. Let's set it to the time stamp
of the spec file itself to make the build reproducible.

When building a package in a build system, such as koji or cbs, logs are
the only thing which can be used to diagnose failures. Make them verbose
since human friendly output of V=0 build doesn't really help when a

Even though we never format the device on the QEMU command line,
as it's a platform serial device that's not user-instantiable,
we should still make sure it's available before using it.

Now that <serial> and <console> on s390/s390x behave a bit more like the
other architectures, remove this extra differentation, and use sclp
console by default for new guests.  New virtio consoles can still be
added, and it is actually needed because of the limited number of
instances for sclp and sclplm.

Introduce specific a target types with two models for the console
devices (sclp and sclplm) used in s390 and s390x guests, so isa-serial
is no more used for them.

This makes <serial> usable on s390 and s390x guests, with at most only
a single sclpconsole and one sclplmconsole devices usable in a single
guest (due to limitations in QEMU, which will enforce already at
runtime).

We can finally introduce a specific target model for the pl011 device
used by mach-virt guests, which means isa-serial will no longer show
up to confuse users.

We make sure migration works in both directions by interpreting the
isa-serial target type, or the lack of target type, appropriately
when parsing the guest XML, and skipping the newly-introduced type
when formatting if for migration. We also verify that pl011 is not
used for non-mach-virt guests and add a bunch of test cases.

The existing implementation set the address type for all serial

such as usb-serial and pci-serial; moreover, some decisions were

This attribute was used to decide whether to format the type
attribute of the <target> element, but the logic didn't take into
account all possible cases and as such could lead to unexpected
results. Moreover, it's one more thing to keep track of, and can
easily fall out of sync with other attributes.

Now that we have VIR_DOMAIN_CHR_SERIAL_TARGET_TYPE_NONE, we can
use that value to signal that no specific target type has been
configured for the serial device and as such the attribute should
not be formatted at all. All other values are now formatted.

The devicePostParse() callback is invoked for all devices so that
drivers have a chance to set their own specific values; however,
virDomainDefAddImplicitDevices() runs *after* the devicePostParse()
callbacks have been invoked and can add new devices, in which case
the driver wouldn't have a chance to customize them.

Work around the issue by invoking the devicePostParse() callback
after virDomainDefAddImplicitDevices(), only for the first serial
devices, which might have been added by it. The same was already
happening for the first video device for the very same reason.

This will become important later on, when we will change
virDomainDefAddConsoleCompat() not to set a targetType for
automatically added serial devices.

The blockdev-add code provides a mechanism to sanely provide user
and password-secret arguments for iscsi without placing them on the
command line to be viewable by a 'ps -ef' type command or needing
to create separate -iscsi devices for each disk/volume found.

So modify the iSCSI command line building to check for the presence
of the capability in order properly setup and use the domain master
secret object to encrypt the password in a secret object and alter
the parameters for the command line to utilize.

Modify the xml2argvtest to exhibit the syntax for both disk and
hostdev configurations.

Detect the capability via the query-qmp-schema for blockdev-add
to find the 'password-secret' parameter that will allow the iSCSI
code to use the master secret object to encrypt the secret for an
and only need to provide the object id of the secret on the command
line thus obsfuscating the passphrase.

Rather than building the "file" string in qemuBuildSCSIHostdevDrvStr
build it in the called helper.

Since it's not longer used to shuttle the @secinfo, let's remove
the private hostdev completely.

Rather than placing/using privateData about secinfo in the hostdev,
let's use the virStorageSource private data instead.

Rather than picking apart the two pieces we need/want (path, hosts,
and auth)- let's allocate/use a virStorageSourcePtr for iSCSI storage.

The end result is that qemuBuildSCSIiSCSIHostdevDrvStr doesn't need
to "fake" one for the qemuBuildNetworkDriveStr call.
