In the unlikely case the iSCSI session path exists, but does not
contain an entry starting with "target", we would silently use
an initialized value.
Rewrite the function to correctly report errors.
On PPC the legacy passthrough is not supported and only
VFIO is supported. So, the checks at places to confirm if the
host is passthrough capable checks only legacy, fix it. This
is seen at only one place now.

Unfortunately, we can't just call qemuDomainMachineIsPSeries()
here, because we don't have a virDomainDef instance; that said,
the open-coded check should match said function as closely as
possible.
Use it in virNetServerClientGetInfo to switch back to using
the URI-format (separated by ':') instead of the SASL format
(separated by ';').
Also use it in the error message reported by virNetServerAddClient.
This partially reverts commit 9b45c9f049.
It changed the default format of socket address from the one SASL
requires, but did not adjust all the callers.
It also removed the test coverage for it.
Revert most of the changes except the virSocketAddrFormatFull support
for URI-formatted strings.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1345743 while
reverting the format used by virt-admin's client-info command from
the URI one to the SASL one.

Move the enum into a new src/util/virsecret.h, rename it to be
virSecretLookupType. Add a src/util/virsecret.h in order to perform
a couple of simple operations on the secret XML and virSecretLookupTypeDef
for clearing and copying.
This includes quite a bit of collateral damage, but the goal is to remove
the "virStorage*" and replace with the virSecretLookupType so that it's
easier to to add new lookups that aren't necessarily storage pool related.

Every driver provides a refreshPool impl, and many other critical
places in the code unconditionally call it without checking if
it exists, so this check is pointless
One can not issue monitor commands manually during async calls thru
designated API while this could be useful for testing/debugging purposes.
qemuDomainQemuMonitorCommand uses job of type QEMU_JOB_MODIFY and any async
call disable parallel execution of this type of job. The only state that is
changed is taint variable. AFAIU the only place we can mess is resetting
taint flag in qemuProcessStop routine under some async job. But this can not
happen thanx to both virDomainObjIsActive check in qemuDomainQemuMonitorCommand
and resetting active status in qemuProcessStop before taint flag.
Change job type to QEMU_JOB_QUERY and thus make the API call available for
most of async jobs.

This code was attempting to handle some implicit <console> XML
formatting for manually assembled DomainDef, since previously the
console<->serial compat copying was only done at XML parse time.
Nowadays it's done via virDomainDefPostParse ->
virDomainDefAddConsoleCompat, which all manual DomainDef builders
already call, so we can drop this workaround.
When domXML contains only <console type='pty'> and no corresponding
<serial>, the console is "stolen" [1] and used as the first <serial>
device. When this "stolen" console is accessed from the libxl driver
(in libxlConsoleCallback and libxlDomainOpenConsole), check if the
targetType is VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL, and use the
"stolen" device in def->serials[0] instead. Prior to this change,
creating a domain with input XML containing only a <console> device
and subsequently attempting to access its console with
'virsh console' would fail
error: internal error: character device <null> is not using a PTY

Allow gathering available vcpu ids, their state and offlinability via
the qemu guest agent. The maximum id was chosen arbitrarily and ought
to be enough for everybody.
Documentation for the "guest-set-vcpus" command describes a proper
algorithm how to set vcpus. This patch makes the following changes:
- state of cpus that has not changed is not updated
- if the command was partially successful the command is re-tried with
the rest of the arguments to get a proper error message
- code is more robust against malicious guest agent
- fix testsuite to the new semantics
To allow finer-grained control of vcpu state using guest agent this API
can be used to individually set the state of the vCPU.
This will allow to better control NUMA enabled guests and/or test
various vCPU configurations.
Add a rather universal API implemented via typed params that will allow
to query the guest agent for the state and possibly other aspects of
guest vcpus.
Since it's rather tedious to write the dispatchers for functions that
return an array of typed parameters (which are rather common) let's add
some rpcgen code to generate them.

Since we support QEMU 0.12 and later, checking for support of specific flags
added prior to that isn't necessary.
Thus start with the base of having the "-o options" available for the
qemu-img create option and then determine whether we have the compat
option for qcow2 files (which would be necessary up through qemu 2.0
where the default changes to compat 0.11).
Adjust test to no long check for NONE and FLAG options as well was removing
results of tests that would use that option.

So far this is only useful for recalculating NUMA memory size,
which this function cannot parse.
This will let us generate USB addresses based on this flag.
In the case of chassisNr (used to set chassis_nr of a pci-bridge
controller), 0 is reserved for / used by the pci[e]-root bus. In the
base of busNr, a value of 0 would mean that the root bus had no places
available to plug in new buses, including the pxb itself (the
documentation I wrote for pxb even noted the limit of busNr as 1.254).
NB: oddly, the "chassis" attribute, which is used for pcie-root-port
and pcie-switch-downstream-port *can* be set to 0, since it's the
combination of {chassis, slot} that needs to be unique, not chassis by
itself (and slot 0 of pcie-root is reserved, while pcie-*-port can use
*only* slot 0).

Since introduction of the DAC security driver we've documented that
seclabels with a leading + can be used with numerical uid. This would
not work though with the rest of libvirt if the uid was not actually
used in the system as we'd fail when trying to get a list of
supplementary groups for the given uid. Since a uid without entry in
/etc/passwd (or other user database) will not have any supplementary
groups we can treat the failure to obtain them as such.
This patch modifies virGetGroupList to not report the error for missing
users and makes it return an empty list or just the group specified in
@gid.
All callers will grant less permissions to a user in case of failure of
this function and thus this change is safe.

Currently identical to virBitmapParse.
Also change one test case to use the new function.
The '-usb' option doesn't have any effect for aarch64 mach-virt
guests, so the fact that it's currently enabled by default is not
really causing any issue.
However, that might change in the future (although unlikely), and
having it as part of the QEMU command line can cause confusion to
someone looking through the process list.
Avoid it completely, like it's already happening for q35.

There has been some progress lately in enabling virtio-pci on
aarch64 guests; however, guest OS support is still spotty at best,
so most guests are going to be using virtio-mmio instead.
Currently, mach-virt guests are closely modeled after q35 guests,
and that includes always adding a dmi-to-pci-bridge that's just
impossible to get rid of. While that's acceptable (if suboptimal)
for q35, where you will always need some kind of PCI device anyway,
mach-virt guests should be allowed to avoid it.
This is going to be important later when we received
DEVICE_DELETED event on the qemu monitor. If we do,
virDomainDefFindDevice() is called to find the device for given
device alias in the virDomainDef tree. When we enable removal for
redirdevs we need to include them in the lookup process too.

Our current detection code uses just the number of CPU features which
need to be added/removed from the CPU model to fully describe the CPUID
data. The smallest number wins. But this may sometimes generate wrong
results as one can see from the fixed test cases. This patch modifies

this model results in a longer list of additional features.
