Rather than build a guest and installer instance depending on where
we are in the UI, track each input property in an explicit class, so
we can rebuild the guest/installer on demand with data accumulated
up to that point.
This makes the flow easier to follow and simplifies a lot of hacks we
have to do when backing up through the wizard, because we are trying
to unwind changes from an existing object, rather than just blowing
it away and easily reassembling it with updated info.

For the dialog flow, these options are the same, the only effect
is that there's no longer an initial network boot phase.
PXE is dependent on an external server setup that is not common
in the scheme of things, so giving it a first class option on the
front of the new VM wizard isn't really sensible. Users that want
to PXE boot can easily do so via the 'customize before install'
option, or just manually create a VM and edit the boot device as
they see fit.
Explicitly advertising a Manual option is nicer for users that
just want to create a VM and deal with install later, among many
other minor use cases.

macvtap is problematic for inexperienced users so we shouldn't
be broadly advertising it, plus our device listing was incomplete
anyways.
Both bridge and macvtap device listing are largely dependent on
the libvirt virInterface APIs, which have varying degrees of
completeness across distros and are not particularly reliable to
begin with.
Drop both of these in favor of the available support for manually
specifying a device name

Similar to the bridge option. We will be removing the explicit
device listing support soon, so this will be required for specifying
a macvtap device

For a decade, qemu and xen and virt-manager work together to
make setting a manual keymap redundant. Advertising it in the UI does
more harm than good, because users may think they need to specify
one when in the vast majority of cases it will give worse behavior.
With the XML editing UI, users still have a way to do this by hand
if they really know what they are doing.

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
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.
The memory hotplug changes only work on libvirt 5.3.0, among a few
other pieces. Still do the XML compare but skip domain define if
the new check_version_define comparison fails.
Name and forward mode config are always visible. ipv4, ipv6, and
domain name are under their own expanders which are collapsed by
default.
This will fit better with the XML editor pattern and reduce the
urge to squeeze more UI elements into the now smaller wizard
This makes it easier for people to change install media afterwards
if they want:
https://bugzilla.redhat.com/show_bug.cgi?id=1508377
But also this makes it more clear that if users want to use virtio-win,
they need to add an additional CDROM and not try to reuse the install
CDROM device
On first run of the app we will check to see if libvirt and qemu
are installed, and if not, offer to install them. In theory anyways.
In practice this stuff breaks repeatedly and is a pain to test because
every desktop has their own API provider with subtly different behavior.
My last round of testing about 12 months ago: apper on KDE was completely
busted and apparently unmaintained (although that may have changed lately),
gnome-software is the latest packagekit provider on gnome and completely
changes the semantics of the API compared to old style gnome-packagekit
that break a lot of virt-manager assumptions.
So I'm tired of it and want it all gone. Still use systemd to try and
check if libvirtd is running, and provide error messages at startup
to guide people.
The new UI is handled in mediacombo. It's a combobox+entry. The
combobox is prepopulated with host cdrom/floppy devices, and
previously used media paths from gsettings
The new VM wizard no longer has separate UI for cdrom device vs
ISO media. The choosecd dialog is gone all together, and media
is changed with the 'apply' button like all other details changes
This is just a big nasty commit.
Turn the OS inspection page into an always available page that
shows the libosinfo name from the domain metadata XML. Use oslist.py
and have it absorb more of the common behavior needed by create.py
and details.py. Add UI tests for it all
I know openstack uses tcp consoles but for end users I've never
really heard about it. RHEL compiles out udp as well. I'm fine telling
users to go to the cli and use virt-xml for this use case.
Use this opportunity to drop a lot of code that only simplified the
case when there are tons of char options we need to consider
On KDE the testManagerWindowCleanup test clicks right on the border and
the drag operation fails, bringing down the test. Clicking a bit lower

Kind of a big mess but it was difficult to untangle piecemeal.
Basically this drops nearly all the centralized window tracking
in engine.py and moves it to each UI class. If manager.py wants
to open a details window it does it directly, and vmmDetails tracks
the window object list itself. This simplifies things and makes
the code easier to follow.
There's still some weirdness with vmmConnect and connection callbacks,
but future patches will break those apart.
Could mean a code error but more likely is just slightly racy
UI bits disappearing that we weren't looking for anyways, so hide
it behind a debug statement
If we wait for windows to become active in the window manager before
we try to do any clickyclicky, this solves a lot of the race
conditions I was trying to work around widget by widget
