Some OSes, as Fedora, have variants (which we rely to be standardised on
osinfo-db side), which we can use to return the most generic tree
possible, in case no profile is specified, in order to avoid failing to
install a "Workstation" system because a "Server" variant tree was used.

QEMU version 2.12.1 introduced a performance feature under commit
be7773268d98 ("target-i386: add KVM_HINTS_DEDICATED performance hint").
Support for this performance hint was added in libvirt 5.7.0 by commit
cb12c59dac04 ("qemu: support for kvm-hint-dedicated performance hint").
This patch extends virt-install's existing --features option to insert the
appropriate XML into the guest definition if this feature is specified
on the command line.
E.g. --features='kvm.hint-dedicated.state=on' would result
in the following XML:
<features>
...
<kvm>
<hint-dedicated state='on'/>
</kvm>
...
</features>

Some osed have multiple short-ids, like debian10 also has debianbuster.
Use the API if it's available. This will make it easier to remove
our back compat aliases eventually
This was originally added so we had stable paths in the XML. It's
not required anymore, and if it becomes an issue we should fix it
by scrubbing the compared xml
Let's set "media" as installation source for all the ISOs, even the
net-installer ones, as this can be dealt with on osinfo-db side.

Let's not expose the user/root password in the CLI and, instead, let's
rely on a file passed by the admin and read the password from there.
'CVE-2019-10183' has been assigned to the virt-install --unattended
admin-password=xxx disclosure issue.

libvirt already does this for pretty much all QEMU guests, but
ARM virt guests for example don't get a memory balloon by default
at that level of the stack.
virt-manager is in a good position to make sure defaults are
consistent across architectures, and there's no downside in having
the device in the XML passed to libvirt anyway.

We're going to slightly change how the device is handled in
a minute, and we want to make sure we don't break existing
functionality while doing so.
Note that the existing singleton-config-* test cases already
provide coverage for both enabling and disabling the memory
balloon in virt-install.

Init a shared log instance in virtinst/logger.py, and use that
throughout the code base, so we aren't calling directly into
'logging'. This helps protect our logging output from being
cluttered with other library output, as happens with some
'requests' usage
ALLSTORES was implicitly using dict() ordering. This exposed
a bug in our code on debian ci which was nice, but it should
be deterministic. Hardcode the ordering
Not sure I want to go down that route if we can avoid it. Instead
just fold the full_id support into the existing option handling.
Streamline the OSVariantData usage throughout the cli tools
Replace the unreleased --os-variant OSNAME,install=location with just
--install OSNAME
Unwind the --unattended dependency on upfront --os-variant while
we are at it, since they are all intertwined. Now we can just do:
virt-install --install OSNAME
and
virt-install --install OSNAME --unattended
This reverts commit 66fe00ddee.
Turns out it's not that simple. Indeed libvirt sets the default
when no <vcpus> XML is present, but if you do --vcpus cpuset=X
libvirt will error that there's no vcpu value set. So for back
compat and generate safety let's keep setting it.
--install kernel_args=X acts like --extra-args. If
kernel_args_overwrite=yes is also specified, it overwrites whatever
default kernel args we would have used for the install method.
This adds a field in gsettings and preferences UI to enable
XML editing. It's off by default. The XML tab page is still visible,
but the textview is not editable, and there's a warning at the top:
XML editing is disabled in 'Preferences'.
Only enable it if you know what you are doing.
When the setting is enabled, the warning goes away and the textview
is editable. This puts a roadblock up for people that don't know what
they are doing, but still advertises the feature and keeps the
UI surface difference fairly small between on/off states.
It was disabled with commit 2aca20141e back in 2015, but
these days we have it enabled for all other architectures and
there doesn't seem to be a good reason for s390x to keep being
the outlier.

This uses the same logic as virt-manager. The name is mostly
derived from --os-variant naming, but we have fallback defaults too.
Print the name to stdout so users are informed about what we are
doing.
This puts all the default resource setting in one place, and the
only place that was depending on it, as virt-manager explicitly sets
the values on its own. This will be used in future patches to add
more default setup and report the values to the user
These include platform checks - libvirt & QEMU - as well as
configuration - SEV is only supported with UEFI.
Another configuration requirement made in this patch is Q35 machine,
since ADM recommends Q35 in their setups even though SEV can work with
the legacy PC machine type, but we'd have to turn on
virtio-non-transitional for all virtio devices with some other potential
pitfalls along the way.

The data in question are 'cbitpos' denoting which addressing bit is the
encryption bit and 'reduced_phys_bits' denoting how many physical
address space we lose by turning on the encryption. Both of these are
hypervisor dependent and thus will be the same for all the guest
residing on the same host, but need to be specified for future migration
purposes.
But given we can probe them from domain capabilities, we don't need the
user to provide them and thus enhancing cli user experience. This
requires a new _SEV domaincapabilities XML class to be created so that
we can query the specific properties.

Policy is a 4-byte bitfield used to turn on/off certain behaviour within
the SEV firmware. For a detailed table of supported flags, see
https://libvirt.org/formatdomain.html#launchSecurity.
Most of the flags are related to advanced features (some of them don't
even exist at the moment), except for the first 2 bits which determine
whether debug mode should be turned on and whether the same key should
be used to encrypt memory of multiple guests respectively.
>From security POV, most users will probably want separate keys for
individual guests, thus the value 0x03 was selected as the policy
default.

Introduce both the launchSecurity XML and parser classes. While at it,
add launchSecurity as a property instance to the Guest class too.
The parser requires the 'type' argument to be mandatory since in the
future it will determine different code paths, therefore
'--launchSecurity foo=bar' is incorrect.

And pass it down to treemedia, which acts on our script wrapper
object. This is conceptually a bit simpler because we can see in
one place what data feeds the script build process, depending on
installer props
* Make all API calls go through the _OsMedia object
* Move most of the unattended specific processing to unattended.py
* Rename requires_internet to is_netinst to clarify what it is checking
SupportCache.check_support(SUPPORT_FOOBAR, args) becomes
SupportCache.foobar(args)
And SupportCache absorbs the caching infrastructure from
VirtinstConnection.
For now we add some hackery to hide the API change from callers, but
this will be undone in the next patch
