While it's very unlikely to have QEMU that supports SEV-SNP but
doesn't support plain SEV, for completeness sake we ought to
query SEV capabilities if QEMU supports either. And similarly to
QEMU_CAPS_SEV_GUEST we need to clear the capability if talking to
QEMU proves SEV is not really supported.
This in turn removes the 'sev-snp-guest' capability from one of
our test cases as Peter's machine he uses to refresh capabilities
is not SEV capable. But that's okay. It's consistent with
'sev-guest' capability.

Commit 7c8e606b64 attempted to fix
the specification of the ramfb property for vfio-pci devices, but it
failed when ramfb is explicitly set to 'off'. This is because only the
'vfio-pci-nohotplug' device supports the 'ramfb' property. Since we use
the base 'vfio-pci' device unless ramfb is enabled, attempting to set
the 'ramfb' parameter to 'off' this will result in an error like the
following:

When the chain names and table name used by the nftables firewall
backend were changed in commit
958aa7f274, I forgot to change the test
data file base.nftables, which has the extra "list" and "add
chain/table" commands that are generated for the first test case of
networkxml2firewalltest.c. When the full set of tests is run, the
first test will be an iptables test case, so those extra commands
won't be added to any of the nftables cases, and so the data in
base.nftables never matches, and the tests are all successful.
However, if the test are limited with, e.g. VIR_TEST_RANGE=2 (test #2
will be the nftables version of the 1st test case), then the commands
to add nftables table/chains *will* be generated in the test output,
and so the test will fail. Because I was only running the entire test
series after the initial commits of nftables tests, I didn't notice
this. Until now.
base.nftables has now been updated to reflect the current names for
chains/table, and running individual test cases is once again
successful.

iifname/oifname need to lookup the string that contains the name of

no extra work is required other than changing the commandline option.
If it was the case that the interface could be deleted and re-added
during the life of the rule, we would have to use Xifname (since
deleting and re-adding the interface would result in ifindex
changing), but for our uses this never happens, so Xif works for us,

The iptables backend (which was used as the model for the nftables
backend) used the same "filter" and "nat" tables used by other
services on the system (e.g. firewalld or any other host firewall
management application), so it was possible that one of those other
services would be blocking DNS, DHCP, or TFTP from guests to the host;
we added our own rules at the beginning of the chain to allow this
traffic no matter if someone else rejected it later.
But with nftables, each service uses their own table, and all traffic
must be acepted by all tables no matter what - it's not possible for
us to just insert a higher priority/earlier rule that will override
some reject rule put in by, e.g., firewalld. Instead the firewalld (or
other) table must be setup by that service to allow the traffic. That,
along with the fact that our table is already "accept by default",
makes it possible to eliminate the individual accept rules for DHCP,
DNS, and TFTP. And once those rules are eliminated, there is no longer
any need for the guest_to_host or host_to_guest tables.

Also (again because nobody else is using the private "libvirt_network"

than creating a subordinate chain as done in the iptables backend.

When destroying a network, the network driver has always assumed that
it knew what firewall rules had been added as the network was
started. This was usually correct - I only recall one time in the past
that the firewall rules added by libvirt were changed. But if the
exact rules used for a network *were* ever changed from one
build/version of libvirt to another, then we would end up attempting
to remove rules that hadn't been added, and could possibly *not*
remove rules that had been added.
The solution to this to not make such brash assumptions about the
past, but instead to save (in the network status object at network
start time) a list of all the rules needed to remove the rules that
were added for the network, and then use that saved list during
network destroy to remove exactly what was previous added.
Beyond making net-destroy more precise, there are other benefits:
1) We can change the details of the rules we add for networks from one
build/release of libvirt to another and painlessly upgrade.
2) The user can switch from one firewall backend to another by simply
changing the setting in network.conf and restarting
libvirtd/virtnetworkd.
In both cases, the restarted libvirtd/virtnetworkd will remove all the
rules that had been previously added (based on the network status),
and then add new rules (saving the new removal commands back into the
network status)

It still can have only one useful value ("iptables"), but once a 2nd
value is supported, it will be selectable by setting
"firewall_backend=nftables" in /etc/libvirt/network.conf.
If firewall_backend isn't set in network.conf, then libvirt will check
to see if FIREWALL_BACKEND_DEFAULT_1 is available and, if so, set
that. (Since FIREWALL_BACKEND_DEFAULT_1 is currently "iptables", this
means checking to see it the iptables binary is present on the
system). If the default backend isn't available, that is considered a
fatal error (since no networks can be started anyway), so an error is
logged and startup of the network driver fails.
NB: network.conf is itself created from network.conf.in at build time,
and the advertised default setting of firewall_backend (in a commented
out line) is set from the meson_options.txt setting
"firewall_backend_default_1". This way the conf file will have correct
information no matter what ordering is chosen for default backend at
build time (as more backends are added, settings will be added for
"firewall_backend_default_n", and those will be settable in
meson_options.txt and on the meson commandline to change the ordering
of the auto-detection when no backend is set in network.conf).
virNetworkLoadDriverConfig() may look more complicated than necessary,
but as additional backends are added, it will be easier to add checks
for those backends (and to re-order the checks based on builders'
preferences).

(This paragraph is for historical reference only, described only to
avoid confusion of past use of the name with its new use) In a past
life, virFirewallBackend had been a private static in virfirewall.c
that was set at daemon init time, and used to globally (i.e. for all
drivers in the daemon) determine whether to directly execute iptables
commands, or to run them indirectly via the firewalld passthrough
API. This was removed in commit d566cc55, since we decided that using
the firewalld passthrough API is never appropriate.
Now the same enum, virFirewallBackend, is being reintroduced, with a
different meaning and usage pattern. It will be used to pick between
using nftables commands or iptables commands (in either case directly
handled by libvirt, *not* via firewalld). Additionally, rather than
being a static known only within virfirewall.c and applying to all
firewall commands for all drivers, each virFirewall object will have
its own backend setting, which will be set during virFirewallNew() by
the driver who wants to add a firewall rule.
This will allow the nwfilter and network drivers to each have their
own backend setting, even when they coexist in a single unified
daemon. At least as important as that, it will also allow an instance
of the network driver to remove iptables rules that had been added by
a previous instance, and then add nftables rules for the new instance
(in the case that an admin, or possibly an update, switches the driver
backend from iptables to nftable)
Initially, the enum will only have one usable value -
VIR_FIREWALL_BACKEND_IPTABLES, and that will be hardcoded into all
calls to virFirewallNew(). The other enum value (along with a method
of setting it for each driver) will be added later, when it can be
used (when the nftables backend is in the code).

firewall, it takes one of the objects out of the list of commands to

to Add a "rule" (now "cmd" aka command) to the list that will, when
applied/run, remove a rule from the host firewall.)

When testPipeFeeder copies the XML document into the padded buffer, it
tells virStrcpy that 'xmlsize' bytes are available. This is under
reporting size by 1 byte, and as a result it fails to copy the trailing
'\n' replacing it with '\0'. The return value of virStrcpy wasn't
checked, but was reporting this truncation.
When testPipeFeeder then sends the padded buffer down the pipe, it asks
to send 'emptyspace + xmlsize + 1' bytes, which means it sends the data,
as well as the trailing '\0' terminator.
Both bugs combined mean it is sending '\0\0' as the last bytes, instead
of '\n' which was intended. When virFileReadAll reads data from the
pipe, it ends up adding another '\0' resulting in a very NUL terminated
string ('\0\0\0'). This is all harmless, but should be fixed regardless.

the buffer. It can be prevented from hanging on ppc64 by increasing the
size of the buffer.
What is happening is a result of differing page sizes, altering the
overall pipe capacity size, since pipes on linux default to 16 pages
in size and thus have architecture specific capacity when measured
in bytes.
* On x86, testPipeFeeder opens R+W, tries to write 140kb and
write() blocks because the pipe is full. This gives time for
virsh to start up, and it can open the pipe for O_RDONLY
since testPipeFeeder still has it open for write. Everything
works as intended.
* On ppc64, testPipeFeeder opens R+W, tries to write 140kb
and write() succeeds because the larger 64kb page size
resulted in greater buffer capacity for the pipe. It thus
quickly closes the pipe, removing the writer, and triggering
discard of all the unread data. Now virsh starts up, tries
to open the pipe for O_RDONLY and blocks waiting for a new
writer to open it, which will never happen. Meson kills
the test after 30 seconds.
NB, every now & then, it will not block because virsh starts
up quickly enough that testPipeFeeder has not yet closed the
write end of the pipe, giving the illusion of correctness.
The key flaw here is that it should not have been using O_RDWR
in testPipeFeeder. Synchronization is required such that both
virsh and testPipeFeeder have their respective ends of the pipe
open before any data is sent. This is trivially arranged by
using O_WRONLY in testPipeFeeder.

The mpx feature was removed from the corresponding qemu cpu models.
With mpx in the libvirt cpu models, libvirt believes the feature
to be implicitly enabled when creating qemu VMs, while in fact it is
disabled.
This became an issue when commit 94eacd5a5f introduced new vmx-*
features, of which some are dependent on mpx (see "feature_dependencies"
table in qemu target/i386/cpu.c), e.g. vmx-exit-clear-bndcfgs and
vmx-entry-load-bndcfgs. These features cannot be enabled by qemu
without also mpx being enabled, leading to the error message
error: Failed to create domain from testdomain.xml

When using vSPC (Virtual Serial Port Concentrator) in vSphere the actual

Instead of parsing the vspc URL with something along the lines of
`virURIParse(vspc ? vspc : fileName)`, which could lead to us reporting
information that is very prune to misuse (the vSPC seemingly has a
protocol on top of the telnet connection; redefining the domain would
change the behaviour; the URL might have a fragment we are not saving;

Commit v10.0.0-265-ge67bca23e4 added a `active_config` and
`defined_config` to nodedev mdev internal XML handling.
`defined_config` can be filled at XML parse time, but `active_config`
must be filled in by nodedev driver. This wasn't implemented for the
test driver however, which caused virt-manager test suite regressions.
Working example:
```
$ virsh --connect test:///home/crobinso/src/virt-manager/tests/data/testdriver/testdriver.xml nodedev-dumpxml mdev_8e37ee90_2b51_45e3_9b25_bf8283c03110

<parent>css_0_0_0023</parent>
<capability type='mdev'>
<type id='vfio_ccw-io'/>

Broken example:
```

Memory at a6800000 (64-bit, non-prefetchable) [size=16K]
For cold plugged devices this is not a problem, because firmware
sets PCI controllers in a way that make devices behind them just
work. Problem arises if such PCI device is to be hot plugged.
Since the PCI device wasn't present at cold boot, firmware could
not take it into calculations and the amount of reserved memory
is not sufficient.
Introduce a know that allows users overriding value computed by

If path to the build directory contains spaces (e.g. meson setup

not just a colon but also a space character is a delimiter for
LD_PRELOAD [1]. Hence, a test using mock tries to preload
something like libvirt.git/a b/libsomethingmock.so which is
interpreted by glibc as two separate strings: "libvirt.git/a",
"b/libsomethingmock.so".
One trick to get around this is to set LD_PRELOAD to just the
shared object file (without path) and let glibc find the mock in
paths specified in LD_LIBRARY_PATH (where only a colon or a
semicolon are valid separators [1]). This can be seen in action
by running say:

Add a check for file existence to the virSecurity*RestoreFileLabel functions,

caused failures in qemusecuritytest, which mocks stat, chown, etc as part of

The machine types historically have a default USB controller populated
via '-usb' which libvirt assumed implicitly. Qemu will use 'pci-ohci'
for both if '-usb' is used.
Unfortunately an USB controller instantiated via '-usb' is unusable as
the bus name libvirt generates doesn't reflect the real name qemu uses,
and thus no libvirt-defined USB devices can be put on the controller.
This patch will populate the default USB controller into the XML and
select it's model to 'pci-ohci' unconditionally as the machine would
fail to start with '-usb' if that controller model is not available.
This patch doesn't try to make any other assumptions about
auto-populated model of USB controllers, which means that for an
explicit USB controller without model a different model will be picked.
Note that this will likely cause ABI differences and break migration for
the two machine types, in the corner case when the default USB
controller would be populated, but given that both are obsolete board
types and USB was unusable it doesn't make sense to keep supporting this
specific case when '-usb' was formatted.

The 'size' of a 'shmem' device is parsed and formatted as a "scaled"

precission loss combined with the fact that the value was validated only

on first parse a value < 1 MiB would be accepted, but would be formatted
to the XML as 0 MiB as it was non-zero but truncated and a subsequent

Fix the issue by moving the validator, which ensures that the number is

Rather than always binding to the vfio-pci driver, use the new
function virPCIDeviceFindBestVFIOVariant() to see if the running
kernel has a VFIO variant driver available that is a better match for
the device, and if one is found, use that instead.
virPCIDeviceFindBestVFIOVariant() function reads the modalias file for
the given device from sysfs, then looks through
/lib/modules/${kernel_release}/modules.alias for the vfio_pci alias
that matches with the least number of wildcard ('*') fields.
The appropriate "VFIO variant" driver for a device will be the PCI
driver implemented by the discovered module - these drivers are
compatible with (and provide the entire API of) the standard vfio-pci
driver, but have additional device-specific APIs that can be useful
for, e.g., saving/restoring state for migration.
If a specific driver is named (using <driver model='blah'/> in the
device XML), that will still be used rather than searching
modules.alias; this makes it possible to force binding of vfio-pci if
there is an issue with the auto-selected variant driver.

The long-deprecated use of <driver name='vfio|xen|kvm'/> in domain xml
for <hostdev> devices was only ever necessary during the period when
libvirt (and the Linux kernel) supported both VFIO and "legacy KVM"
styles of hostdev device assignment for QEMU. This became pointless
many years ago when legacy KVM device assignment was removed from the
kernel, and support for that style of device assignment was completely
disabled in the libvirt source in 2019 (commit
v5.6.0-316-g2e7225ea8c).
Nevertheless, there were instances of <driver name='vfio'/> in the
unit test data that were then (unnecessarily) propagated to several
more tests over the years. This patch cleans out those unnecessary
explicit settings of driver name='vfio' in all QEMU unit test data,
proving that the attribute is no longer (externally) needed. (A later
patch which adds a 2nd attribute to the <driver> element will include
a test case that explicitly exercises the driver name attribute).

Xen only supports a single type of PCI hostdev assignment, so it is
superfluous to have <driver name='xen'/> peppered throughout the
config. It *is* necessary to have the driver type explicitly set in
the hostdev object before calling into the hypervisor-agnostic "hostdev
manager" though (otherwise the hostdev manager doesn't know whether it
should do Xen-specific setup, or VFIO-specific setup).
Historically, the Xen driver has checked for "default" driver name
(i.e. not set in the XML), and set it to "xen', during the XML
postparse, thus guaranteeing that it will be set by the time the
object is sent to the hostdev manager at runtime, but also setting it
so early that a simple round-trip of parse-format results in the XML
always containing an explicit <driver name='xen'/>, even if that
wasn't specified in the original XML.
The QEMU driver *doesn't* set driver.name during postparse though;
instead, it waits until domain startup time (or device attach time for
hotplug), and sets the driver.name then. The result is that a
parse-format round trip of the XML in the QEMU driver *doesn't* add in
the <driver name='vfio'/>.
This patch modifies the Xen driver to behave similarly to the QEMU
driver - the PostParse just checks for a driver.name that isn't
supported by the Xen driver, and any explicit setting to "xen" is
deferred until domain runtime rather than during the postparse, thus
Xen domain XML also doesn't get extraneous <driver name='xen'/>.
This delayed setting of driver.name of course results in slightly
different xml2xml parse-format results, so the unit test data is
modified accordingly.
