Currently we hardcode these defaults for installing VMs:
<on_poweroff>destroy</on_poweroff>
<on_reboot>destroy</on_reboot>
<on_crash>destroy</on_crash>
And these for post-install config:
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
But this has some issues. on_crash=restart is problematic in that most
configs don't support it, and some like virtuozzo actively reject it.
Additionally this we should leave as much to libvirt defaults as we
can, which are more sensible in this case.
Drop everything except setting on_reboot=destroy for the install time
case (which is required for our config changes). Since on_poweroff
and on_crash already default to 'destroy', the install time config
is unchanged, and the post-install config now on_crash=destroy instead
of 'restart'.
The s390 on_crash=preserve workaround is dropped, which was intended
to avoid a reboot loop caused by on_crash=reboot
Each guest type can have its own capabilities and we should always ask
only for those capabilities.
The old approach was to get capabilities from libvirt and then for
example cycle trough all guests and return True, if any guest type
supports kvm or pae, etc.
Now we check those capabilities only for the correct guest type
according to defaults and input from user.

Make it clear which ones are used for the caps unit tests, and which
are for cli/UI testing and can be updated at will. And drop a bunch
of outdated stuff.
We are just mirroring the behavior that virt-manager (and boxes) have
used for a while now.
In my experience the average user is confused by their VMs suspending,
so for our sake I'd rather make people opt into this feature.
The image compression setting has a noticably detrimental effect on
spice graphics quality. It's meant to be used for spice VDI but the
vast majority of people don't use spice in a way that makes bandwidth
usage matter.
Boxes has already done this for a while as well:

Turn it off by default if creating the VM on a local connection.
