23594ccda9 vsh: Cmd aliases lookups should return results for the aliased command
Unfortunately, we have a number of aliases in virsh and even though
these are not visible any more, we have to support them. The problem is
that when trying to print help for the alias, we get SIGSEGV because
there isn't any @def structure anymore and we need to query the command
being aliased instead.

da60878c4c vsh: Drop redundant definition searches from vshCmd{def,Grp}Help
These helpers are called from a single place only - cmdHelp wrapper and
just before the wrapper invokes the helpers, it performs the search,
either for command group or for the command itself, except the result is
discarded and the helper therefore needs to do it again. Drop this
inefficient handling and pass the @def structure rather than a name,
thus preventing the helper from needing to perform the search again.

In the future, this function is going to be called from
vshReadlineParse() to provide parsed input for completer
callbacks. The idea is to allow the callbacks to provide more
specific data. For instance, for the following input:

  virsh # domifaddr --domain fedora --interface <TAB><TAB>

the --interface completer callback is going to be called. Now, it
is more user friendly if the completer offers only those
interfaces found in 'fedora' domain. But in order to do that it
needs to be able to retrieve partially parsed result.

74a13be4a4 build: Use XDR_CFLAGS in more places
Since update to glibc-2.26 removed the /usr/include/rpc/rpc.h we used until now,
it showed us a problem with not using XDR_CFLAGS properly.  On linux that
variable has usually -I/usr/include/tirpc because we already probe for it
properly, we just don't use it everywhere we need.  It is needed by wireshark
dissector as well as testutilsqemu.c (through includes) so the build fails with:

wireshark/src/packet-libvirt.c:33:10: fatal error: rpc/xdr.h: No such file or directory
 #include <rpc/xdr.h>
          ^~~~~~~~~~~

and

In file included from ../src/logging/log_manager.h:29:0,
                 from ../src/qemu/qemu_domain.h:40,
                 from testutilsqemu.c:11:
../src/logging/log_protocol.h:9:10: fatal error: rpc/rpc.h: No such file or directory
 #include <rpc/rpc.h>
          ^~~~~~~~~~~

Since lot of tests use testutilsqemu.c it is easier to add XDR_CFLAGS to
AM_CFLAGS than adding it to all $binary_CFLAGS.  It's just for tests and we
already have bunch of CFLAGS there anyway.

Commit fdeac7a05f tried to fix the output
of 'virsh domxml-to-native --help' by switching types around. One of the
changes broke the option parser. VSH_OT_ARGV should be used only for
variable argument count, not to make the help generator look pretty.

The correct option type in this case is VSH_OT_STRING as it's not
mandatory now since it can be substituted by using --domain.

This makes --help for this command look incorrect, but the parser works
as it should.

79b7ac43fa qemu: add the print of page size in cmd domjobinfo
The command "info migrate" of qemu outputs the dirty-pages-rate during
migration, but page size is different in different architectures. So
page size should be output to calculate dirty pages in bytes.

Page size is already implemented with commit
030ce1f8612215fcbe9d353dfeaeb2937f8e3f94 in qemu.
Now Implement the counter-part in libvirt.

So we refer to the terms 'persistent' and 'transient' across the whole

create command affects it, i.e. explicitly stating that domain created
via the 'create' command are going to be transient or persistent,
depending on whether there is an existing persistent domain with a
matching <name> and <uuid>, in which case it will remain persistent, but
will run using a one-time configuration, otherwise it's going to be
transient and will vanish once destroyed.

the tvb_new_subset() function was renamed to

step and rename to tvb_new_subset_remaining() directly (see
Wireshark commit 0ecfc7280cf3d7). The reasoning is that there is
no other protocol in the packet than libvirt. Therefore, from the
point that libvirt dissector takes over till the end of the

2453501fc8 virsh: Track when create pkttyagent
https://bugzilla.redhat.com/show_bug.cgi?id=1374126

Due to how the processing for authentication using polkit works, the
virshConnect code must first "attempt" an virConnectOpenAuth and then
check for a "special" return error code VIR_ERR_AUTH_UNAVAILABLE in
order to attempt to "retry" the authentication after performing a creation
of a pkttyagent to handle the challenge/response for the client.

However, if pkttyagent creation is not possible for the authentication
being attempted (such as perhaps a "qemu+ssh://someuser@localhost/system"),
then the same failure pattern would be returned and another attempt to
create a pkttyagent would be done. This would continue "forever" until
someone forced quit (e.g. ctrl-c) from virsh as the 'authfail' was not
incremented when creating the pkttyagent.

So add a 'agentCreated' boolean to track if we've attempted to create the
agent at least once and force a failure if that creation returned the same
error pattern.

This resolves a possible never ending loop and will generate an error:

error: failed to connect to the hypervisor
error: authentication unavailable: no polkit agent available to authenticate action 'org.libvirt.unix.manage'

NB: If the authentication was for a sufficiently privileged client, such as
qemu+ssh://root@localhost/system, then the remoteDispatchAuthList "allows"
the authentication to use libvirt since @callerUid would be 0.

'virsh nodedev-list --cap' not only for existing mdev devices but also
for devices that support creation of mdev devices, since one day libvirt

(just like we do for NPIV/vHBA).

4b9af8625a virsh-domain-monitor: add human readable output for 'domblkinfo'.
https://bugzilla.redhat.com/show_bug.cgi?id=1330940

The virsh command 'domblkinfo' returns the capacity, allocation and phisycal
size of the devices attached in a domain. Usually, this sizes are very big
and hard to understand and calculate. This commits introduce a human readable
support to check the size of each field easilly.

For example, the command before:

virsh # domblkinfo my_domain hda
Capacity:       21474836480
Allocation:     14875545600
Physical:       21474836480

and after this patch:

virsh # domblkinfo my_domain hda --human
Capacity:       20.000G
Allocation:     13.900G
Physical:       20.000G

c8a637c7d0 virsh: add helpers for getting domain XML for XPath purposes
In virsh we quite often get the domain XML just to initialize the XPath
parser so that we can extract information.

Add helpers which will simplify this by wrapping the getting of the XML
and parsing it along with error reporting.

Additionally a second helper also gets the domain object from the
parameters and releases it so that functions which need the XML as only
source of data can be simplified further.

conf/domain_conf.c:14926:12: error: this statement may fall through [-Werror=implicit-fallthrough=]
         if (src->targetTypeAttr != tgt->targetTypeAttr)

a48c674fba storage: Move and rename disk backend label checking
Rather than have the Disk code having to use PARTED to determine if
there's something on the device, let's use the virStorageBackendDeviceProbe.
and only fallback to the PARTED probing if the BLKID code isn't built in.

This will also provide a mechanism for the other current caller (File
System Backend) to utilize a PARTED parsing algorithm in the event that
BLKID isn't built in to at least see if *something* exists on the disk
before blindly trying to use. The PARTED error checking will not find
file system types, but if there is a partition table set on the device,
it will at least cause a failure.

Move virStorageBackendDiskValidLabel and virStorageBackendDiskFindLabel
to storage_backend and rename/rework the code to fit the new model.

Update the virsh.pod description to provide a more generic description
of the process since we could now use either blkid or parted to find
data on the target device.
