d47de9e698 tests: Add aarch64-traditional-pci test
This test shows what happens when you add a traditional PCI
device such as pci-serial to a pure PCIe machine type such
as aarch64/virt.

412afdb8f4 util: introduce virSocketAddrParseAny
When preparing for migration, the libxl driver creates a new TCP listen
socket for the incoming migration by calling virNetSocketNewListenTCP,
passing the destination host name. virNetSocketNewListenTCP calls
virSocketAddrParse to check if the host name is a wildcard address, in
which case it avoids adding the AI_ADDRCONFIG flag to the hints passed to
getaddrinfo. If the host name is not an IP address, virSocketAddrParse
reports an error

error : virSocketAddrParseInternal:121 : Cannot parse socket address
'myhost.example.com': Name or service not known

But virNetSocketNewListenTCP succeeds regardless and the overall migration
operation succeeds.

Introduce virSocketAddrParseAny and use it when simply testing if a host
name/addr is parsable.

6dd84f6850 qemu_cgroup: Handle device mapper targets properly
https://bugzilla.redhat.com/show_bug.cgi?id=1557769

Problem with device mapper targets is that there can be several
other devices 'hidden' behind them. For instance, /dev/dm-1 can
consist of /dev/sda, /dev/sdb and /dev/sdc. Therefore, when
setting up devices CGroup and namespaces we have to take this
into account.

This bug was exposed after Linux kernel was fixed. Initially,
kernel used different functions for getting block device in
open() and ioctl(). While CGroup permissions were checked in the
former case, due to a bug in kernel they were not checked in the
latter case. This changed with the upstream commit of
519049afead4f7c3e6446028c41e99fde958cc04 (v4.16-rc5~11^2~4).

Add a new kind of XML output test for the files in qemuxml2argvtest
where we can validate setup and defaults applied when starting up the
VM.

This is achieved by formatting of the definition processed by the
qemuxml2argvtest into a XML and it's compared against files in
qemuxml2startupxmloutdata. This test is automatically executed if the
output file is present and it's skipped otherwise.

The first example test case is created from 'disk-drive-shared' test

452c2cc7e7 qemu_monitor_json: Properly check "return" type
My commit 2e0d6cdec4 claimed qemuMonitorJSONCheckError guarantees
"return" object exists in the JSON reply. But it only makes sure the key
is there, while the type of the value is not checked. A lot of callers
do not care since they only want to see whether their QMP command failed
or not, but any caller which needs to read some data from the reply
wants to make sure the correct data type was returned.

This patch adds a new API called qemuMonitorJSONCheckReply which calls
qemuMonitorJSONCheckError and checks "return" contains a value of the
specified type.

It was not possible to determine whether virJSONValueObjectAddVArgs and

Fix this by passing in a pointer to the pointer so that it can be
cleared once it's successfully consumed and the callers don't have to
second-guess leaving a chance of leaking or double freeing the value
depending on the ordering.

Fix all callers to pass a double pointer too.
