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.

Add an info message that these can be set via the
'Customize before install' option. Duplicating this doesn't add a ton
of value here IMO

we did with bridge/macvtap domain <interface>

* macvtap is kinda problematic in general because it doesn't provide
out of the box host<->guest communication, and it requires a
special XML option just to get working ipv6. Users that know they
want it usually know this distinction, but if someone chooses it
without understanding the implications it can cause confusion.
This puts it hovering the intermediate/advanced user line which
makes me want to not advertise it as prominently as we currently do,
with an explicit list of host interfaces

Part of this is that the only source_mode that will work in a useful

portgroups are a way to group logical chunks of settings inside

advanced enough to edit the XML directly.

This removes it all. The openvswitch piece was not properly wired

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.
Signed-off-by: Cole Robinson <crobinso@redhat.com>
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 XML editor ui is a two tabbed notebook, one 'Details' tab
and one 'XML' tab. The latter has a gtksourceview and allows editing
the raw libvirt XML for whatever the selected object is.
API users will programmatically insert the xmleditor notebook into
their UI, with the existing UI under the details tab.
vmmVMWindow handles all the menuing, and coordinating between the
console, snapshots, and details panel. Simplifies the details
code a bit which will help when we add xmlediting
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
Rather than a mix of radio buttons and other combo boxes.
This follows the pattern we more commonly use in other UI, and
makes it easier to hide UI elements that aren't relevant for
specific choices, like the possibly large SR-IOV selector
This wizard is sufficiently obscure that I don't think it's
really valuable to try to explain networking concepts with
UI labels. If users don't know what they are trying to create
by using this wizard, there's no way we are going to adequately
explain to them what they are looking at. The example values
should be self explanatory enough anyways
This only applies for inter VM traffic when ipv6 networking is
disabled, which IMO is pretty obscure. If users want ipv6
connectivity, just enabling ipv6 will handle it appropriately
