As can be seen from VmCheck_GetVersion() in open-vm-tools code,
CMD_GETVERSION should return vmware-vmx-type in ECX register.
Default is to fake host as VMware ESX server. But user can control
this value by "-global vmport.vmware-vmx-type=X".

vmware-vmx-version is a number returned from CMD_GETVERSION which specifies
to guest VMware Tools the the host VMX version. If the host reports a number
that is different than what the guest VMware Tools expects, it may force
guest to upgrade VMware Tools. (See comment above VERSION_MAGIC and
VmCheck_IsVirtualWorld() function in open-vm-tools open-source code).
For better readability and allow maintaining compatability for guests
which may expect different vmware-vmx-version, make vmware-vmx-version a
VMPort object property. This would allow user to control it's value via
"-global vmport.vmware-vmx-version=X".

This is used as a signal for VMware Tools to know if a command it
attempted to invoke, failed or is unsupported. As a result, VMware Tools
will either report failure to user or fallback to another backdoor command
in attempt to perform some operation.
A few examples:
* open-vm-tools TimeSyncReadHost() function fallbacks to
CMD_GETTIMEFULL command when CMD_GETTIMEFULL_WITH_LAG
fails/unsupported.
* open-vm-tools Hostinfo_NestingSupported() function verifies
EAX != -1 to check for success.
* open-vm-tools Hostinfo_VCPUInfoBackdoor() functions checks
if reserved-bit is set to indicate command is unimplemented.

vmport_ioport_read() returns the value that should propagate to vCPU EAX
register when guest reads VMPort IOPort (i.e. By x86 IN instruction).
However, because vmport_ioport_read() calls cpu_synchronize_state(), the
returned value gets overridden by the value in QEMU vCPU EAX register.
i.e. cpu->env.regs[R_EAX].
To fix this issue, change vmport_ioport_read() to explicitly override
cpu->env.regs[R_EAX] with the value it wish to propagate to vCPU EAX
register.

Add the VMBus infrastructure -- bus, devices, root bridge, vmbus state
machine, vmbus channel interactions, etc.
VMBus is a collection of technologies. At its lowest layer, it's a message
passing and signaling mechanism, allowing efficient passing of messages to and
from guest VMs. A layer higher, it's a mechanism for defining channels of
communication, where each channel is tagged with a type (which implies a
protocol) and a instance ID. A layer higher than that, it's a bus driver,
serving as the basis of device enumeration within a VM, where a channel can
optionally be exposed as a paravirtual device. When a server-side (paravirtual
back-end) component wishes to offer a channel to a guest VM, it does so by
specifying a channel type, a mode, and an instance ID. VMBus then exposes this
in the guest.
More information about VMBus can be found in the file
vmbuskernelmodeclientlibapi.h in Microsoft's WDK.

-numa node,memdev=mem0

Default RAM backend depends on numa_uses_legacy_mem(), which is
infulenced by -numa options on CLI or set-numa-node QMP command
at preconfig time. If QEMU is started with '-preconfig'
without -numa, it will lead to creating default RAM backend
even if later set-numa-node is used to assing RAM to NUMA nodes
using 'memdev' NUMA option.
That at best will waste RAM object created by default and with
next patch adding a check to prevent usage of conflicting
'-M memory-backend' and '-numa memdev'
options, it will make QEMU error out if user tries to configure
NUMA at preconfig time with memdev option, making set-numa-node
unusable.
To fix issue, move preconfig loop before default RAM backend is
created, so that numa_uses_legacy_mem() would take into account
effects of set-numa-node commands executed at preconfig time.

Just build the container when run-coverity-scan is invoked with
--update-tools-only --docker. This requires moving the "docker build"
logic into the update_coverity_tools function.
The only snag is that --update-tools-only --docker requires access to
the dockerfile. For now just report an error for --src-tarball, and
"docker build" will fail if not in a source tree. Another possibility
could be to host our container images on a public registry, and use
"FROM qemu:fedora" to make the Dockerfile small enough that it can be
included directly in the run-coverity-scan script.

Our trusted docker wrapper allows run-coverity-scan to run with both
docker and podman.
For the "run" phase this is transparent; for the "build" phase however
scripts are replaced with a bind mount (-v). This is not an issue
because the secret option is meant for secrets stored globally in the
system and bind mounts are a valid substitute for secrets that are known
to whoever builds the container.

It is possible, that shutdown on target occurs earlier than migration
finish. In this case we crash in bdrv_release_dirty_bitmap_locked()
on assertion "assert(!bdrv_dirty_bitmap_busy(bitmap));" as we do have
busy bitmap, as bitmap migration is ongoing.
We'll fix bitmap migration to gracefully cancel on early shutdown soon.
Now let's fix iotest 194 to wait migration completion before shutdown.
Note that in this test dest_vm.shutdown() is called implicitly, as vms

Actually, not waiting migration finish is a wrong thing, but the test

When setting the memory tables, qemu uses a memory region's userspace
address to look up the region's MemoryRegion struct. Among other things,
the MemoryRegion contains the region's offset and associated file
descriptor, all of which need to be sent to the backend.
With VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS, this logic will be
needed in multiple places, so before feature support is added it
should be moved to a helper function.
This helper is also used to simplify the vhost_user_can_merge()
function.
