While peer-to-peer migration enters the Confirm phase even if the
Perform phase fails, the client which initiated a non-p2p migration will
never call virDomainMigrateConfirm* API if the Perform phase failed.
Thus we need to explicitly reset migration before reporting a failure
from the Perform phase API.

Migration with old QEMU which does not support query-migrate-parameters
would fail because the QMP command is called unconditionally since the
introduction of TLS migration. Previously it was only called if the user
explicitly requested a feature which uses QEMU migration parameters. And
even then the situation was not ideal, instead of reporting an
unsupported feature we'd just complain about missing QMP command.

Trivially no migration parameters are supported when
query-migrate-parameters QMP command is missing. There's no need to
report an error if it is missing, the callers will report better error
if needed.

Rather than using "ret = -1" and cleanup processing, alter the return
path on failure to goto error and then just return the data.got.

In the error path, we no longer check for ret < 0, we just can free
anything added to the array and return -1 directly.

If several RA routes are found for the same device, only list that
device once in the error message.

Format the attributes in a separate buffer and only
print the element if it's not empty.

Make adding new attributes easier.

Eliminate the big condition at the start.
Instead use a buffer and only format the element if the buffer
is non-empty.

Instead of figuring out upfront whether <input> will be a single
or a pair element, format the subelements into a separate buffer
and close <input/> early if this buffer is empty.

There's lot more to document about the nodedev driver, besides PCI and

During 'matrix' testing of all possible combinations I found that if
device is formated with "gpt" first, then an attempt is made to format
using "mac", a startup will fail.

Deeper analysis by Peter Krempa indicates that the "mac" table fits
into the first block on the disk. Since the GPT disklabel is stored
at LBA address 1 it is not overwritten at all. Thus it's apparent that
the (blkid) detection tool then prefers GPT over a older disklabel.

The GPT disklabel has also a secondary copy at the last LBA of the disk.

So, follow the same logic as the logical pool in clearing a 1MB swath
at the beginning and end of the device to avoid potential issues with
larger sector sizes for the device.

Also fixed a minor formatting nit in virStorageBackendDeviceIsEmpty call.

Since a sector size may be larger than 512 bytes, let's just increase
the size to wipe to 1MB rather than 2KB

Rather than open code it, use the new function which uses the wipe algorithm
in order to zero the front and tail of the partition.

Create a wrapper/helper that can be used to call the storage backend
wipe helper - storageBackendVolWipeLocalFile for future use by logical
and disk backends to clear out the partition table rather than having
each open code the same algorithm.

Add bool 'zero_end' and logic that would allow a caller to wipe specific
portions of a target device either from the beginning (the default) or
from the end when zero_end is true.

This will allow for this code to wipe out partition table information
from a device.

There were a few bugs in keycodemap tool that broke it
when run on python circa 2.7.5 or older, which affected
RHEL builds.
