net-user-passt.args was generated early during testing of the passt
qemu commandline, when qemuxml2argvtest was using
DO_TEST("net-user-passt"). This was later changed to
DO_TEST_CAPS_LATEST(), so the file net-user-passt.x86_64-latest.args
is used instead, but the original (now unused) test file was
accidentally added to the original patch. This patch removes it.

This attribute was added to support setting the --interface option for
passt, but in a post-push/pre-9.0-release review, danpb pointed out
that it would be better to use the existing <source dev='xxx'/>
attribute to set --interface rather than creating a new attribute (in
the wrong place). So we remove backend/upstream, and change the passt
commandline creation to grab the name for --interface from source/dev.

Currently, the ThreadContext object is generated whenever we see
.host-nodes attribute for a memory-backend-* object. The idea was
that when the backend is pinned to a specific set of host NUMA
nodes, then the allocation could be happening on CPUs from those
nodes too. But this may not be always possible.
Users might configure their guests in such way that vCPUs and
corresponding guest NUMA nodes are on different host NUMA nodes
than emulator thread. In this case, ThreadContext won't work,
because ThreadContext objects live in context of the emulator
thread (vCPU threads are moved around by us later, when emulator
thread finished its setup and spawned vCPU threads - see
qemuProcessSetupVcpus()). Therefore, memory allocation is done by
emulator thread which is pinned to a subset of host NUMA nodes,
but tries to create a ThreadContext object with a disjoint subset
of host NUMA nodes, which fails.

This consists of (1) adding the necessary args to the qemu commandline
netdev option, and (2) starting a passt process prior to starting
qemu, and making sure that it is terminated when it's no longer
needed. Under normal circumstances, passt will terminate itself as
soon as qemu closes its socket, but in case of some error where qemu
is never started, or fails to startup completely, we need to terminate

This implements XML config to represent a subset of the features
supported by 'passt' (https://passt.top), which is an alternative
backend for emulated network devices that requires no elevated
privileges (similar to slirp, but "better").
Along with setting the backend to use passt (via <backend
type='passt'/> when the interface type='user'), we also support
passt's --log-file and --interface options (via the <backend>
subelement logFile and upstream attributes) and its --tcp-ports and
--udp-ports options (which selectively forward incoming connections to
the host on to the guest) via the new <portForward> subelement of
<interface>. Here is an example of the config for a network interface
that uses passt to connect:
<interface type='user'>
<mac address='52:54:00:a8:33:fc'/>
<ip address='192.168.221.122' family='ipv4'/>
<model type='virtio'/>
<backend type='passt' logFile='/tmp/xyzzy.log' upstream='eth0'/>
<portForward address='10.0.0.1' proto='tcp' dev='eth0'>
<range start='2022' to='22'/>
<range start='5000' end='5099' to='1000'/>
<range start='5010' end='5029' exclude='yes'/>
</portForward>
<portForward proto='udp'>
<range start='10101'/>
</portForward>
</interface>
In this case:
* the guest will be offered address 192.168.221.122 for its interface
via DHCP
* the passt process will write all log messages to /tmp/xyzzy.log
* routes to the outside for the guest will be derived from the
addresses and routes associated with the host interface "eth0".
* incoming tcp port 2022 to the host will be forwarded to port 22
on the guest.
* incoming tcp ports 5000-5099 (with the exception of ports 5010-5029)
to the host will be forwarded to port 1000-1099 on the guest.
* incoming udp packets on port 10101 will be forwarded (unchanged) to
the guest.

You may notice that neither of our domaincapsdata test shows any

these store the full host CPU expansion (hostCPU.fullQEMU)
because that is runtime piece of information and not formatted

Now that we have qemuMonitorGetCPUModelExpansion() aware of

2) Arch is either x86 or arm.
It may look like modifying the first call to
qemuMonitorGetCPUModelExpansion() inside of
virQEMUCapsProbeQMPHostCPU() would be sufficient but it is not.
We really need to ask QEMU for full expansion and the first call
does not guarantee that.
For the test data, I've just copied whatever
'query-cpu-model-expansion' returned earlier, therefore there are
no hv-* props. But that's okay - the full expansion is not stored
in cache (and thus not formatted in

In one of recent commits I've introduced a new test case to
commandtest. In the test case I'm using poll() to wait for data
on a pipe (the write end is passed to commandhelper). However, on
FreeBSD the POLLIN semantic is a bit different:
POLLIN Data other than high priority data may be read
without blocking.
Well, the pipe is non-blocking, so even if there's no data to be
read the flag is set (and subsequent read() returns 0). On the
other hand, POLLHUP is set too, BUT, if the commandhelper manages
to write everything into the pipe and die right after we'd get
both POLLIN and POLLHUP after the very first time poll() returns.
That's very unfortunate, but okay - we can just check whether
read() returned zero and break from the reading loop.
