20ad55a8fd driver: introduce a driver method for probing default URIs
Currently the virDrvConnectOpen method is supposed to handle both
opening an explicit URI and auto-probing a driver if no URI is
given. Introduce a dedicated virDrvConnectURIProbe method to enable the
probing functionality to be split from the driver opening functionality.

It is still possible for NULL to be passed to the virDrvConnectOpen
method after this change, because the remote driver needs special
handling to enable probing of the URI against a remote libvirtd daemon.

a2fd657b86 lxc: allow use of lxc:///system URI as preferred format
Historically we have used a bare lxc:/// URI for connecting to LXC. This
is different from our practice with QEMU, UML, Parallels, Libxl, BHyve
and VirtualBox drivers, which all use a path of '/system' or '/session'
or both.

By making LXC allow '/system', we have fully standardized on the use of
either '/system' or '/session' for all the stateful drivers that run
inside libvirtd.

Support for lxc:/// is of course maintained for back-compat.

a8ea89d258 xen: encourage use of xen:///system URI as preferred format
Historically we have used a bare xen:/// URI for connecting to the
legacy Xen driver. The new libxl Xen driver follows the new practice
of allowing '/system' as a path, as well as bare '/' for compat with
the old Xen driver.

This documents xen:///system as the preferred format for Xen, leaving
xen:/// as an undocumented feature just for back-compat.

550950e5b3 qemu: Format gic-version=2 on the command line
Up until now we have only formatted non-default GIC versions on
the command line, in order to maintain compatibility with older
QEMU versions that didn't implement the gic-version option to
begin with; however, doing so is entirely unnecessary for newer
QEMU versions, where the option is available. Moreover, having
the GIC version formatted on the command line at all times
ensures that QEMU changing its own defaults doesn't affect the
ABI of libvirt guests.

A few test cases are removed to avoid extra churn. It doesn't
matter for coverage, as those scenarios are already covered by
other parts of the test suite.

This patch is better viewed with 'git show -w'.

4d7384eb9d util: don't check for parallel iteration in hash-related functions
This is the responsability of the caller to apply the correct lock
before using these functions. Moreover, the use of a simple boolean
was still racy: two threads may check the boolean and "lock" it
simultaneously.

Users of functions from src/util/virhash.c have to be checked for
correctness. Lookups and iteration should hold a RO
lock. Modifications should hold a RW lock.

Most important uses seem to be covered. Callers have now a greater
responsability, notably the ability to execute some operations while
iterating were reliably forbidden before are now accepted.

a5a777a8ba qemu: Obtain reference on monConfig
Because we allow a QEMU_JOB_DESTROY to occur while we're starting
up and we drop the @vm lock prior to qemuMonitorOpen, it's possible
that a domain destroy operation "wins" the race, calls qemuProcessStop
which will free and reinitialize priv->monConfig. Depending on the
exact timing either qemuMonitorOpen will be passed a NULL @config
variable or it will be using free'd (and possibly reclaimed) memory
as the @config parameter - neither of which is good.

Resolve this by localizing the @monConfig, taking an extra reference,
and then once we get the @vm lock again removing our reference since
we are done with it.

3c9ba9c1cd rpc: refactor way connection object is generated for remote dispatch
Calling a push_privconn method to directly push the connection object
name into the arg list is inconvenient. Refactor so that we acquire
the connection variable name upfront, and push it to the arg list
separately. This allows various hardcoded usage of "priv->conn" to
be parameterized.

I haven't been able to come up with a single scenario in which
the code in question would be executed; even if there was one,
it would be due to the user specifying a *partial* PCI topology
in the guest XML, which is of course entirely unsupportable and
thus providing even the slightest hint that doing so is in any
way a good idea is actively harmful.

When applying the log filters, one has to define the more specific
filters before the generic ones, because the first filter that matches
will be applied. However, we've been missing this information in the
config, so it always has been a trial-error scenario figuring out that
e.g. '4:util 1:util.pci' doesn't actually enable verbose logging on the
src/util/virpci.c module because 4:util will be matched first.

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).

da1ade7a52 remote: remove some __sun conditionals
The libvirtd daemon has some arbitrary logic to drop privileges, but
only on Solaris platforms. This was added during Xen days, when Xen was
the only driver running in libvirtd. There's no expectation or testing
that this works with the new libxl stack, nor whether dropping
privileges breaks any of the secondary drivers. Finally, we'll be
splitting drivers out into their own independant daemons, so this won't
be applicable to libvirtd in future anyway.

The remote driver client meanwhile arbitrarily disables daemon
auto-spawn when connecting as non-root, breaking a key feature of
libvirt unprivileged connections.

Since we've not had any contributions for Solaris since circa 2012
and we don't do any CI testing we should consider this platform
unmaintained and thus reasonable to remove this cruft. If someone steps
forward to maintain Solaris again, this code would need re-evaluating to
come up with something more targetted.

There's various __sun conditionals in the Xen driver code, but those are
not touched. This is all for the legacy Xen driver, which will be
entirely removed at some point in future, so not benefit to hacking out
just the Solaris parts.

This identified the missing admin_max_clients example in the virtlogd

65824a7e45 rpc: remove remains of obsolete log_buffer_size config parameter

  commit c0c8c1d7bb
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Mon Mar 3 14:54:33 2014 +0000

    Remove global log buffer feature entirely

    A earlier commit changed the global log buffer so that it only
    records messages that are explicitly requested via the log
    filters setting. This removes the performance burden, and
    improves the signal/noise ratio for messages in the global
    buffer. At the same time though, it is somewhat pointless, since
    all the recorded log messages are already going to be sent to an
    explicit log output like syslog, stderr or the journal. The
    global log buffer is thus just duplicating this data on stderr
    upon crash.

    The log_buffer_size config parameter is left in the augeas
    lens to prevent breakage for users on upgrade. It is however
    completely ignored hereafter.

    Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

This was in the 1.2.3 release, and 4 years is sufficient time for a
graceful upgrade path for augeas, so all remaining traces are now

83edaf4435 libxl: don't hardcode scheduler weight
Long ago in commit dfa1e1dd53 the scheduler weight was accidentally
hardcoded to 1000. Weight is a setting with no unit since it is
relative to the weight of other domains. If no weight is specified,
libxl defaults to 256.

Instead of hardcoding the weight to 1000, honor any <shares> specified
in <cputune>. libvirt's notion of shares is synonomous to libxl's
scheduler weight setting. If shares is unspecified, defer default
weight setting to libxl.

Removing the hardcoded weight required some test fixup. While at it,
add an explicit test for <shares> conversion to scheduler weight.

In a recent change b932ed69: "virt-aa-helper: resolve yet to be created

cases where the file being last element of the path was the actual link.

In the case of the last element being the symlink realpath can (and shall)
be called on the full path that was passed.

Examples would be zfs/lvm block devices like:
 <disk type='block' device='disk'>
    <driver name='qemu' type='raw'/>
    <source dev='/dev/mapper/testlvm-testvol1'/>
    <target dev='vdd' bus='virtio'/>
 </disk>
With the target being:
 /dev/mapper/testlvm-testvol1 -> ../dm-0

That currently is rendered as
 "/dev/mapper/testlvm-testvol1" rwk,
but instead should be (and is with the fix):
 "/dev/dm-0" rwk,

677aaeb128 python: Drop explicit version where possible
Some of our scripts are known to work both with Python 2 and
Python 3, so for them we shouldn't be forcing any specific
version of the interpreter when they're called directly; we
always use $(PYTHON) explicitly in our build rules anyway.

e02d102bac qemu: hostdev: Fix the error on VM start with an mdev when IOMMU is off
Commit b4c2ac8d56 made a false assumption that IOMMU support necessary
for an mdev device to be assigned to a VM. Unlike direct PCI assignment,
IOMMU support is not needed for mediated devices, as the physical parent
device provides the isolation, therefore, simply checking for VFIO
presence is enough to successfully start a VM.

Luckily, this issue is not serious, since as of yet, libvirt mandates
mdevs to be pre-created prior to a domain's launch - if it is,
everything does work smoothly even with IOMMU disabled, because the
parent device will ensure the iommu groups we try to access exist.
However, if there are *no* IOMMU groups yet, thus no mdev exists yet, one
would see the following error:

"unsupported configuration: Mediated host device assignment requires VFIO
support"

The error msg above is simply wrong and doesn't even reflect the IOMMU
reality, so after applying this patch one would rather see the following
error in such case instead:

"device not found: mediated device '<UUID>' not found"

3d2e4c3e53 util: mdev: Improve the error msg on non-existent mdev prior to VM start
What one currently gets is:
failed to read '/sys/bus/mdev/devices/<UUID>/mdev_type/device_api': No
such file or directory

This indicates that something is missing within the device's sysfs tree
which likely might be not be the case here because the device simply
doesn't exist yet. So, when creating our internal mdev obj, let's check
whether the device exists first prior to trying to verify the
user-provided model within domain XML.

60b3fcd90c libxl: MigratePrepare: use standard begin and end API pattern
libxlDomainMigrationPrepare adds the incoming domain def to the list
of domains via virDomainObjListAdd, but never adds its own ref to the
returned virDomainObj as other callers of virDomainObjListAdd do.
libxlDomainMigrationPrepareTunnel3 suffers the same discrepancy.

Change both to add a ref to the virDomainObj after a successful
virDomainObjListAdd, similar to other callers. This ensures a consistent
pattern throughout the drivers and allows using the virDomainObjEndAPI
function for cleanup.

For libxlDomainLookupByID and libxlDomainLookupByUUID let's
return a locked and referenced @vm object so that callers can
then use the common and more consistent virDomainObjEndAPI in
order to handle cleanup rather than needing to know that the
returned object is locked and calling virObjectUnlock.

The LookupByName already returns the ref counted and locked object,
so this will make things more consistent.

The libxlDomainMigrateConfirm3Params API locks and ref counts the associated

libxlDomainMigrationConfirm is also used by libxlDomainMigratePerform3Params

properly handled in the API entry point.

Remove the unlock from libxlDomainMigrationConfirm and adjust

b133fac356 qemu: Build usb controller command line more wisely
https://bugzilla.redhat.com/show_bug.cgi?id=1552127

When building command line for USB controllers we have to do more
than just put controller's alias onto the command line. QEMU has
concept of these joined USB controllers. For instance ehci and
uhci controllers need to create the same USB bus. To achieve that
the slave controller needs to refer the master controller. This
worked until we've introduced user aliases because both master
and slave had the same alias. With user aliases slave can have
different alias than master. Therefore, when generating command
line for slave we need to look up the master's alias.
