When any error occurs while processing the websockets handshake,
QEMU just terminates the connection abruptly. This is in violation
of the HTTP specs and does not help the client understand what they
did wrong. This is particularly bad when the client gives the wrong
path, as a "404 Not Found" would be very helpful.
Refactor the handshake code so that it always sends a response to
the client unless there was an I/O error.

NVIDIA has defined a specification for creating GPUDirect "cliques",
where devices with the same clique ID support direct peer-to-peer DMA.
When running on bare-metal, tools like NVIDIA's p2pBandwidthLatencyTest
(part of cuda-samples) determine which GPUs can support peer-to-peer
based on chipset and topology. When running in a VM, these tools have
no visibility to the physical hardware support or topology. This
option allows the user to specify hints via a vendor defined
capability. For instance:
<qemu:commandline>
<qemu:arg value='-set'/>
<qemu:arg value='device.hostdev0.x-nv-gpudirect-clique=0'/>
<qemu:arg value='-set'/>
<qemu:arg value='device.hostdev1.x-nv-gpudirect-clique=1'/>
<qemu:arg value='-set'/>
<qemu:arg value='device.hostdev2.x-nv-gpudirect-clique=1'/>
</qemu:commandline>
This enables two cliques. The first is a singleton clique with ID 0,
for the first hostdev defined in the XML (note that since cliques
define peer-to-peer sets, singleton clique offer no benefit). The
subsequent two hostdevs are both added to clique ID 1, indicating
peer-to-peer is possible between these devices.
QEMU only provides validation that the clique ID is valid and applied
to an NVIDIA graphics device, any validation that the resulting
cliques are functional and valid is the user's responsibility. The
NVIDIA specification allows a 4-bit clique ID, thus valid values are
0-15.

After iothread is enabled internally inside QEMU with GMainContext, we
may encounter this warning when destroying the iothread:
(qemu-system-x86_64:19925): GLib-CRITICAL **: g_source_remove_poll:
assertion '!SOURCE_DESTROYED (source)' failed
The problem is that g_source_remove_poll() does not allow to remove one
source from array if the source is detached from its owner
context. (peterx: which IMHO does not make much sense)
Fix it on QEMU side by avoid calling g_source_remove_poll() if we know
the object is during destruction, and we won't leak anything after all
since the array will be gone soon cleanly even with that fd.

When gcontext is used with iothread, the context will be destroyed
during iothread_stop(). That's not good since sometimes we would like
to keep the resources until iothread is destroyed, but we may want to
stop the thread before that point.
Delay the destruction of gcontext to iothread finalize. Then we can do:
iothread_stop(thread);
some_cleanup_on_resources();
iothread_destroy(thread);
We may need this patch if we want to run chardev IOs in iothreads and
hopefully clean them up correctly. For more specific information,
please see 2b316774f6 ("qemu-char: do not operate on sources from

On a modern server-class ppc host with the following CPU topology:
Architecture: ppc64le
Byte Order: Little Endian
CPU(s): 32
On-line CPU(s) list: 0,8,16,24
Off-line CPU(s) list: 1-7,9-15,17-23,25-31
Thread(s) per core: 1
If both KVM PR and KVM HV loaded and we pass:
-machine pseries,accel=kvm,kvm-type=PR -smp 8
We expect QEMU to warn that this exceeds the number of online CPUs:
Warning: Number of SMP cpus requested (8) exceeds the recommended
cpus supported by KVM (4)
Warning: Number of hotpluggable cpus requested (8) exceeds the
recommended cpus supported by KVM (4)
but nothing is printed...
This happens because on ppc the KVM_CAP_NR_VCPUS capability is VM
specific ndreally depends on the KVM type, but we currently use it
as a global capability. And KVM returns a fallback value based on
KVM HV being present. Maybe KVM on POWER shouldn't presume anything
as long as it doesn't have a VM, but in all cases, we should call
KVM_CREATE_VM first and use KVM_CAP_NR_VCPUS as a VM capability.
This patch hence changes kvm_recommended_vcpus() accordingly and
moves the sanity checking of smp_cpus after the VM creation.
It is okay for the other archs that also implement KVM_CAP_NR_VCPUS,
ie, mips, s390, x86 and arm, because they don't depend on the VM
being created or not.

On a server-class ppc host, this capability depends on the KVM type,

get the HV specific value, even if we explicitely requested PR on
the command line.
This can have an impact if we're using hugepages or a balloon device.
Since we've already created the VM at the time any user calls
kvm_has_sync_mmu(), switching to kvm_vm_check_extension() is
enough to fix any potential issue.

vmstate_save_state is called in lots of places.
Route error returns from the easier cases back up; there are lots
of more complex cases where their own error paths need fixing.

Route the errors from vsmtate_save_state back up through
vmstate_save and out to the normal device state path.
That's the normal error path done.

vmstate_subsection_save (and back down, all rather recursive).
