81cb05b7e8 qemu: Add tpm-crb QEMU device to the command line
Alter qemuBuildTPMDevStr to format the tpm-crb on the command line
and use the enum range checking for valid model.

Add a test case for the formation of the tpm-crb QEMU device
command line. The qemuxml2argvtest changes cannot use the newer
DO_TEST_CAPS_LATEST since building of the command line involves
calling qemuBuildTPMBackendStr which attempts to open the
path to the device (e.g. /dev/tmp0).

38848325df tests: Make sure rom.file='' for PCI devices keeps working
Even though we just introduced the rom.enabled attribute to
properly cover the use case, there might be guests out there
that use the only previously available way of disabling PCI
ROM loading by not opting in to schema validation.

To make sure such guests will keep working going forward,
introduce a test case covering the legacy workaround.

4d11d9a292 qemu: Format rom.enabled attribute for PCI devices
The attribute can be used to disable ROM loading completely
for a device.

This might be needed because, even when the guest is configured
such that the PCI ROM will not be loaded in the PCI BAR, some
hypervisors (eg. QEMU) might still make it available to the
guest in a form (eg. fw_cfg) that some firmwares (eg. SeaBIOS)
will consume, thus not achieving the desired result.

Prepare the tests for adding the new parameter. The parameter was
introduced in qemu-2.7.0, so add a forked version of the test case to
see that it is formatted properly.

This test is also an example how the new testing macros should be used.

3527f9dde6 qemu: deny privilege elevation and spawn in seccomp
If QEMU uses a seccomp blacklist (since 2.11), -sandbox on
no longer tries to whitelist all the calls, but uses sets
of blacklists:
default (always blacklisted with -sandbox on)
obsolete (defaults to deny)
elevateprivileges (setuid & co, default: allow)
spawn (fork & execve, default: allow)
resourcecontrol (setaffinity, setscheduler, default: allow)

If these are supported, default to sandbox with all four
categories blacklisted.

70255fa596 tests: Fix up test numbering in qemuxml2argvtest
Due to conditional execution of virTestRun(), the testCounter was incremented
only if all the cases were run.  When using VIR_TEST_RANGE=x-y, first x/2 of the
increments were skipped and that made figuring out a precise case a PITA.
Moving the condition into the test function makes it way nicer to find out the
test numbers to use in VIR_TEST_RANGE.

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'.

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.

a455d41e3e conf: expand network device callbacks to cover resolving NIC type
Currently the QEMU driver will call directly into the network driver
impl to modify resolve the atual type of NICs with type=network. It
has todo this before it has allocated the actual NIC. This introduces
a callback system to allow us to decouple the QEMU driver from the
network driver.

This is a short term step, as it ought to be possible to achieve the
same end goal by simply querying XML via the public network API. The
QEMU code in question though, has no virConnectPtr conveniently
available at this time.

18c24bc686 qemu: assign correct type of PCI address for vhost-scsi when using pcie-root
Commit 10c73bf1 fixed a bug that I had introduced back in commit
70249927 - if a vhost-scsi device had no manually assigned PCI
address, one wouldn't be assigned automatically. There was a slight
problem with the logic of the fix though - in the case of domains with
pcie-root (e.g. those with a q35 machinetype),
qemuDomainDeviceCalculatePCIConnectFlags() will attempt to determine
if the host-side PCI device is Express or legacy by examining sysfs
based on the host-side PCI address stored in
hostdev->source.subsys.u.pci.addr, but that part of the union is only
valid for PCI hostdevs, *not* for SCSI hostdevs. So we end up trying
to read sysfs for some probably-non-existent device, which fails, and
the function virPCIDeviceIsPCIExpress() returns failure (-1).

By coincidence, the return value is being examined as a boolean, and
since -1 is true, we still end up assigning the vhost-scsi device to
an Express slot, but that is just by chance (and could fail in the
case that the gibberish in the "hostside PCI address" was the address
of a real device that happened to be legacy PCI).

Since (according to Paolo Bonzini) vhost-scsi devices appear just like
virtio-scsi devices in the guest, they should follow the same rules as
virtio devices when deciding whether they should be placed in an
Express or a legacy slot. That's accomplished in this patch by
returning early with virtioFlags, rather than erroneously using
hostdev->source.subsys.u.pci.addr. It also adds a test case for PCIe
to assure it doesn't get broken in the future.

65108d94d0 virQEMUCapsHasPCIMultiBus: assume true if we have no version information
In status XML, we do not store the QEMU version information, we only
format all the capabilities. We dropped QEMU_CAPS_PCI_MULTIBUS
in commit 5b783379 which was released in libvirt 3.2.0.

Therefore the only way of telling if the already running domain
at the time of daemon restart has been started with a QEMU that does
use 'pci.0' or not on PPC is to look at the pci-root controller's
alias. This is not an option if the domain has a user-specified alias
for the pci-root.

Instead of reintroducing the capability, assume 'pci.0' when we have
no version information. That way the only left broken use case would
be the combination of user aliases and very old QEMU.

Partially reverts commit 3a37af1e4.

Since the device is a singleton and shouldn't use additional hardware

6885b51e5f qemu: Add TLS support for Veritas HyperScale (VxHS)
Alter qemu command line generation in order to possibly add TLS for
a suitably configured domain.

Sample TLS args generated by libvirt -

    -object tls-creds-x509,id=objvirtio-disk0_tls0,dir=/etc/pki/qemu,\
    endpoint=client,verify-peer=yes \
    -drive file.driver=vxhs,file.tls-creds=objvirtio-disk0_tls0,\

    -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,\
    id=virtio-disk0

Update the qemuxml2argvtest with a couple of examples. One for a
simple case and the other a bit more complex where multiple VxHS disks
are added where at least one uses a VxHS that doesn't require TLS
credentials and thus sets the domain disk source attribute "tls = 'no'".

Update the hotplug to be able to handle processing the tlsAlias whether
it's to add the TLS object when hotplugging a disk or to remove the TLS
object when hot unplugging a disk.  The hot plug/unplug code is largely
generic, but the addition code does make the VXHS specific checks only
because it needs to grab the correct config directory and generate the
object as the command line would do.

the default DHCP range is x.x.x.15-x.x.x.30. Since we don't
expose these settings yet, it's safer to require shorter prefix
to have room for the defaults.

be6a415e51 qemu: set bind mode for chardev while parsing XML
Currently while parsing domain XML we clear the UNIX path if it matches
one of the auto-generated paths by libvirt.  After that when the guest
is started new path is generated but the mode is also changed to "bind".

In the real-world use-case the mode should not change, it only happens
if a user provides a mode='connect' and path that matches one of the
auto-generated path or not provides a path at all.

Before *reconnect* feature was introduced there was no issue, but with
the new feature we need to make sure that it's used only with "connect"
mode, therefore we need to move the mode change into parsing in order
to have a proper error reported by validation code.

e255cf02b2 qemuBuildMemoryBackendStr: Handle one more corner case

This code is so complicated because we allow enabling the same
bits at many places. Just like in this case: huge pages can be
enabled by global <hugepages/> element under <memoryBacking> or
on per <memory/> basis. To complicate things a bit more, users
are allowed to omit the page size which case the default page
size is used. And this is what is causing this bug. If no page
size is specified, @pagesize is keeping value of zero throughout
whole function. Therefore we need yet another boolean to hold
[use, don't use] information as we can't sue @pagesize for that.

e5a0579996 qemu: Enable NUMA node tag in pci-root for PPC64
This patch addresses the same aspects on PPC the bug 1103314 addressed
on x86.

PCI expander bus creates multiple primary PCI busses, where each of these
busses can be assigned a specific NUMA affinity, which, on x86 is
advertised through ACPI on a per-bus basis.

For SPAPR, a PHB's NUMA affinities are assigned on a per-PHB basis, and
there is no mechanism for advertising NUMA affinities to a guest on a
per-bus basis. So, even if qemu-ppc manages to get some sort of multi-bus
topology working using PXB, there is no way to expose the affinities
of these busses to the guest. It can only be exposed on a per-PHB/per-domain
basis.

So patch enables NUMA node tag in pci-root controller on PPC.

The way to set the NUMA node is through the numa_node option of
spapr-pci-host-bridge device. However for the implicit PHB, the only way
to set the numa_node is from the -global option. The -global option applies
to all the PHBs unless explicitly specified with the option on the
respective PHB of CLI. The default PHB has the emulated devices only, so
the patch prevents setting the NUMA node for the default PHB.

The following cmd line is generated:

  -object

df13c0b477 qemu: Add support for guest CPU cache
This patch maps /domain/cpu/cache element into -cpu parameters:

- <cache mode='passthrough'/> is translated to host-cache-info=on
- <cache level='3' mode='emulate'/> is transformed into l3-cache=on
- <cache mode='disable'/> is turned in host-cache-info=off,l3-cache=off

Any other <cache> element is forbidden.

The tricky part is detecting whether QEMU supports the CPU properties.

The 'host-cache-info' property is introduced in v2.4.0-1389-ge265e3e480,
earlier QEMU releases enabled host-cache-info by default and had no way
to disable it. If the property is present, it defaults to 'off' for any
QEMU until at least 2.9.0.

The 'l3-cache' property was introduced later by v2.7.0-200-g14c985cffa.
Earlier versions worked as if l3-cache=off was passed. For any QEMU
until at least 2.9.0 l3-cache is 'off' by default.

QEMU 2.9.0 was the first release which supports probing both properties
by running device-list-properties with typename=host-x86_64-cpu. Older
QEMU releases did not support device-list-properties command for CPU
devices. Thus we can't really rely on probing them and we can just use
query-cpu-model-expansion QMP command as a witness.

Because the cache property probing is only reliable for QEMU >= 2.9.0
when both are already supported for quite a few releases, we let QEMU
report an error if a specific cache mode is explicitly requested. The
other mode (or both if a user requested CPU cache to be disabled) is
explicitly turned off for QEMU >= 2.9.0 to avoid any surprises in case
the QEMU defaults change. Any older QEMU already turns them off so not
doing so explicitly does not make any harm.
