4e8faa5cdc qemu: domain: Store data for 'secret' object representing http cookies
The http cookies can have potentially sensitive values and thus should
not be leaked into the command line. This means that we'll need to
instantiate a 'secret' object in qemu to pass the value encrypted.

This patch adds infrastructure for storing of the alias in the status
XML.

70d2758a9c qemuDomainSecretStorageSourcePrepare: Change aliases for disk secrets
Originally there was only the secret for authentication so we didn't use
any suffix to tell it apart. With the introduction of encryption we
added a 'luks' suffix for the encryption secrets. Since encryption is
really generic and authentication is not the only secret modify the
aliases for the secrets to better describe what they are used for.

This is possible as we store the disk secrets in the status XML thus
only new machines will use the new secrets.

46e16b553d tests: fix double unlock of monitor in hotplug test
The qemuMonitorTestNew() function returns with the monitor object
locked, and expects it to still be locked when qemuMonitorTestFree
is called.  The qemuhotplug test, however, explicitly unlocks the
monitor, but then forgets to lock it again. As a result the
qemuMonitorTestFree function is unlocking a mutex it doesn't own.

This bug has existed forever, but since we use normal POSIX mutexes
and don't check the return value of pthread_mutex_lock/unlock we
didn't see the error. It was harmless until the switch to the per
monitor event loop which requires the thread synchronization to
work reliably, whereupon it started crashing.

2695191a44 conf: Don't generate machine names with a dot
According to the linked BZ, machined expects either valid
hostname or valid FQDN (see systemd commit
v239-3092-gd65652f1f2). While in case of multiple dots, a
trailing one doesn't violate FQDN, it does violate the rule in
case of something simple, like "domain.". But it's safe to remove
it in both cases.

b47e3b9b5c qemu: agent: sync once if qemu has serial port event
Sync was introduced in [1] to check for ga presence. This
check is racy but in the era before serial events are available
there was not better solution I guess.

In case we have the events the sync function is different. It allows us
to flush stateless ga channel from remnants of previous communications.
But we need to do it only once. Until we get timeout on issued command
channel state is ok.

415e022118 src: fix mixup of stack and heap allocated data in auth callback
In the following recent change:

  commit db72866310
  Author: Daniel P. Berrangé <berrange@redhat.com>
  Date:   Tue Jan 14 10:40:52 2020 +0000

    util: add API for reading password from the console

the fact that "bufptr" pointer may point to either heap or stack
allocated data was overlooked. As a result, when the strdup was
removed, we ended up returning a pointer to the local stack to
the caller. When the caller referenced this stack pointer they
got out garbage which fairly quickly resulted in a crash.

We need to copy the stack buffer into heap memory in the username
case.

However the test is still affected by the host state and the binary
gets invoked if present.

Mock the libxlDomainGetEmulatorType function to stop wasting CPU
cycles every time a 'make check' is run on a system with xen installed.

32363452af tests: refactor event test to not run lock step
The current event loop test suite has two threads running
in lockstep. This was just about viable when we have full
control over the internal details of the event loop impl.
When we're using the GLib event loop though there are
things going on that we don't know about, such as use of
eventfd() file descriptors. This will break the assumptions
in the test suite, causing non-deterministic failures.

This change switches the event loop thread to run fully
asynchronously from the test suite cases. This is slightly
weaker validation, but the only way we can get a reliable
test suite.

calculating the transaction, the code to relabel them and rollback.

To verify that stuff works we also output the list of images to relabel
into the test case output files in qemublocktest.

eb9f6cc4b3 qemu: support interface <teaming> functionality
The QEMU driver uses the <teaming type='persistent|transient'
persistent='blah'/> element to setup a "failover" pair of devices -
the persistent device must be a virtio emulated NIC, with the only
extra configuration being the addition of ",failover=on" to the device
commandline, and the transient device must be a hostdev NIC
(<interface type='hostdev'> or <interface type='network'> with a
network that is a pool of SRIOV VFs) where the extra configuration is
the addition of ",failover_pair_id=$aliasOfVirtio" to the device
commandline. These new options are supported in QEMU 4.2.0 and later.

Extra qemu-specific validation is added to ensure that the device
type/model is appropriate and that the qemu binary supports these
commandline options.

The result of this will be:

1) The virtio device presented to the guest will have an extra bit set
in its PCI capabilities indicating that it can be used as a failover
backup device. The virtio guest driver will need to be equipped to do
something with this information - this is included in the Linux
virtio-net driver in kernel 4.18 and above (and also backported to
some older distro kernels). Unfortunately there is no way for libvirt
to learn whether or not the guest driver supports failover - if it
doesn't then the extra PCI capability will be ignored and the guest OS
will just see two independent devices. (NB: the current virtio guest
driver also requires that the MAC addresses of the two NICs match in
order to pair them into a bond).

2) When a migration is requested, QEMu will automatically unplug the
transient/hostdev NIC from the guest on the source host before
starting migration, and automatically re-plug a similar device after
restarting the guest CPUs on the destination host. While the transient
NIC is unplugged, all network traffic will go through the
persistent/virtio device, but when the hostdev NIC is plugged in, it
will get all the traffic. This means that in normal circumstances the
guest gets the performance advantage of vfio-assigned "real hardware"
networking, but it can still be migrated with the only downside being
a performance penalty (due to using an emulated NIC) during the
migration.

fb0509d06a conf: parse/format <teaming> subelement of <interface>
The subelement <teaming> of <interface> devices is used to configure a
simple teaming association between two interfaces in a domain. Example:

  <interface type='bridge'>
    <source bridge='br0'/>
    <model type='virtio'/>
    <mac address='00:11:22:33:44:55'/>
    <alias name='ua-backup0'/>
    <teaming type='persistent'/>
  </interface>
  <interface type='hostdev'>
    <source>
      <address type='pci' bus='0x02' slot='0x10' function='0x4'/>
    </source>
    <mac address='00:11:22:33:44:55'/>
    <teaming type='transient' persistent='ua-backup0'/>
  </interface>

The interface with <teaming type='persistent'/> is assumed to always
be present, while the interface with type='transient' may be be
unplugged and later re-plugged; the persistent='blah' attribute (and
in the one currently available implementation, also the matching MAC
addresses) is what associates the two devices with each other. It is
up to the hypervisor and the guest network drivers to determine what
to do with this information.

cad65f222f qemu: add capabilities flag for failover feature
Presence of the virtio-net-pci option called "failover" indicates
support in a qemu binary of a simplistic bonding of a virtio-net
device with another PCI device. This feature allows migration of
guests that have a network device assigned to a guest with VFIO, by
creating a network bond device in the guest consisting of the
VFIO-assigned device and a virtio-net-pci device, then temporarily
(and automatically) unplugging the VFIO net device prior to migration
(and hotplugging an equivalent device on the migration
destination). (The feature is called "failover" because the bond
device uses the vfio-pci netdev for normal guest networking, but
"fails over" to the virtio-net-pci netdev once the vfio-pci device is
unplugged for migration.)

Full functioning of the feature also requires support in the
virtio-net driver in the guest OS (since that is where the bond device
resides), but if the "failover" commandline option is present for the
virtio-net-pci device in qemu, at least the qemu part of the feature
is available, and libvirt can add the proper options to both the
virtio-net-pci and vfio-pci device commandlines to indicate qemu
should attempt doing the failover during migration.

This patch just adds the qemu capabilities flag "virtio-net.failover".

3b8feb4793 qemu: capabilities: Replace aliased machine type by copy of the canonical machine
The previous approac of just purging the alias combined with the fact
that we filled in fake machine types in the test data meant that if a
test case used an alias machine type such as 'pc' or 'q35' it would not
properly resolve to the actual data returned by qemu.

This started to be a problem since the CPU driver now looks at the
default CPU reported with the machine type.

This patch replaces the original approach of just removing the alias by
replacing it with a copy of the machine type data which the type would
alias to. This means that we are using the real data while we don't
modify the test output after every qemu upgrade.

Additionally this change will allow us to drop adding the fake machine
types later.

The test fallout is from actually excercising the CPU driver with
actual data.

068efae5b1 qemu: add support for running QEMU driver in embedded mode
This enables support for running QEMU embedded to the calling
application process using a URI:

   qemu:///embed?root=/some/path

Note that it is important to keep the path reasonably short to
avoid risk of hitting the limit on UNIX socket path names
which is 108 characters.

When using the embedded mode with a root=/var/tmp/embed, the
driver will use the following paths:

                logDir: /var/tmp/embed/log/qemu
           swtpmLogDir: /var/tmp/embed/log/swtpm
         configBaseDir: /var/tmp/embed/etc/qemu
              stateDir: /var/tmp/embed/run/qemu
         swtpmStateDir: /var/tmp/embed/run/swtpm
              cacheDir: /var/tmp/embed/cache/qemu
                libDir: /var/tmp/embed/lib/qemu
       swtpmStorageDir: /var/tmp/embed/lib/swtpm
 defaultTLSx509certdir: /var/tmp/embed/etc/pki/qemu

These are identical whether the embedded driver is privileged
or unprivileged.

This compares with the system instance which uses

                logDir: /var/log/libvirt/qemu
           swtpmLogDir: /var/log/swtpm/libvirt/qemu
         configBaseDir: /etc/libvirt/qemu
              stateDir: /run/libvirt/qemu
         swtpmStateDir: /run/libvirt/qemu/swtpm
              cacheDir: /var/cache/libvirt/qemu

       swtpmStorageDir: /var/lib/libvirt/swtpm

e7a65484ba qemu: Refuse to use "ps2" on machines that do not have this bus
The "ps2" bus is only available on certain machines like x86. On
machines like s390x, we should refuse to add a device to this bus
instead of silently ignoring it.

Looking at the QEMU sources, PS/2 is only available if the QEMU binary
has the "i8042" device, so let's check for that and only allow "ps2"
devices if this QEMU device is available, or if we're on x86 anyway
(so we don't have to fake the QEMU_CAPS_DEVICE_I8042 capability in
all the tests that use <input ... bus='ps2'/> in their xml data).

test: let qemuhotplugtest report details of init fails
If virHostdevManagerGetDefault in qemuhotplugtest fails it works
for quite a while to later segfault when accessing
mgr->activePCIHostdevs.

Report the error details and break on a failed init to see the
real issue right away.

5f2fa393f7 util: storagefile: Properly set transport type when parsing NBD strings
When parsing legacy NBD backing file strings such as
'nbd:unix:/tmp/sock:exportname=/' we'd fail to set the transport to
VIR_STORAGE_NET_HOST_TRANS_UNIX. This started to be a problem once we
actually started to generate config of the backing store on the command
line with -blockdev as the JSON code would try to format it as TCP and
fail with:

 internal error: argument key 'host' must not have null value

Set the type properly and add a test.

3caa28dc50 src: replace gmtime_r/localtime_r/strftime with GDateTime
gmtime_r/localtime_r are mostly used in combination with
strftime to format timestamps in libvirt. This can all
be replaced with GDateTime resulting in simpler code
that is also more portable.

There is some boundary condition problem in parsing POSIX
timezone offsets in GLib which tickles our test suite.
The test suite is hacked to avoid the problem. The upsteam
