Since commit c4eedd793 disallowed qcow2 encrypted images to be
used for domains, it no longer makes sense to allow a qcow2
encrypted volume to be created or resized.
Add a test that will exhibit the failure of creation as well
as the xml2xml validation of the format still being correct.
Update the documentation to note the removal of the capability
to create and use qcow/default encrypted volumes.

entropy. Therefore we should mention that in the docs.

This is a regression in behavior caused by commit 37359814. It was
intended to limit the schema to allow only a single subelement of
<rule>, but it is also acceptable for <rule> to have no subelement at
all.
To prevent the same error from reoccurring in the future, the
examples/xml/nwfilter directory was added to the list of nwfilter
schema test directories.

We only formatted the <sev> element when QEMU supported the feature when
in fact we should always format the element to make clear that libvirt
knows about the feature and the fact whether it is or isn't supported
depends on QEMU version, in other words if QEMU doesn't support the
feature we're going to format the following into the domain capabilities
XML:
<sev supported='no'/>
This patch also adjusts the RNG schema accordingly in order to reflect
the proposed change.

The launch-security element can be used to define the security
model to use when launching a domain. Currently we support 'sev'.
When 'sev' is used, the VM will be launched with AMD SEV feature enabled.
SEV feature supports running encrypted VM under the control of KVM.
Encrypted VMs have their pages (code and data) secured such that only the
guest itself has access to the unencrypted version. Each encrypted VM is
associated with a unique encryption key; if its data is accessed to a
different entity using a different key the encrypted guests data will be
incorrectly decrypted, leading to unintelligible data.

(PDH) key and certificate chain which can be used by the guest owner to

keys used for attestation or to provide secret during launch.

TSEG (Top of Memory Segment) is one of many regions that SMM (System Management
Mode) can occupy. This one, however is special, because a) most of the SMM code
lives in TSEG nowadays and b) QEMU just (well, some time ago) added support for
so called 'extended' TSEG. The difference to the TSEG implemented in real q35's
MCH (Memory Controller Hub) is that it can offer one extra size to the guest OS
apart from the standard TSEG's 1, 2, and 8 MiB and that size can be selected in
1 MiB increments. Maximum may vary based on QEMU and is way too big, so we
don't need to check for the maximum here. Similarly to the memory size we'll
leave it to the hypervisor to try satisfying that and giving us an error message
in case it is not possible.

The process used to build the snapshots no longer works because the box
it runs on is outdated. Analysing the web logs shows the majority of
traffic to these links is from search engine bots. With those removed,
there is about 1 hit per day from (probable) humans.
Most users needing a tarball are better served by using official
releases. Those needing latest code are better served by using git
checkout. The tarball snapshots are not compelling enough to invest time
in fixing the script that produces them.

Recently, bhyve started supporting specifying guest CPU topology.
It looks this way:
bhyve -c cpus=C,sockets=S,cores=C,threads=T ...
The old behaviour was bhyve -c C, where C is a number of vCPUs, is
still supported.
So if we have CPU topology in the domain XML, use the new syntax,
otherwise keep the old behaviour.
Also, document this feature in the bhyve driver page.

Problems with the old encryption include weak crypto, corruption of

former, only the pages unit and size are formatted, while for
the latter the pages unit, size, and availability data is formatted.
The virt-xml-validate would fail because it expected something
extra in the host page size output. So split up pagesElem a bit
and create pagesHost and pagesNuma for the differences.
