Specify the memory size by using '-m size=2048k' instead of just '-m 2'.
The new syntax is used when memory hotplug is enabled. To preserve
memory sizing, if memory hotplug is disabled the size is rounded down to
the nearest mebibyte.

We can launch qemu with it, but it will not work since it's not even
probed by the kernel at the mapped address with different machine types
since they are expected to be connected to ISA and not even its newer
LPC counterpart found on q35. And it does not exist on non-x86
architectures.

These are allegedly necessary to keep the output consistent,
but now that we're using a privileged config for the driver we
get the desired behavior out of the box, and as a bonus the
paths match what you would actually see on a regular host.

QEMU deprecated the '-no-acpi' option, thus we should switch to the
modern way to use '-machine'.
Certain ARM machine types don't support ACPI. Given our historically
broken design of using '<acpi/>' without attribute to enable ACPI and
qemu's default of enabling it without '-no-acpi' such configurations
would not work.
Now when qemu reports whether given machine type supports ACPI we can do
a better decision and un-break those configs. Unfortunately not
retroactively.

The iTCO watchdog is part of the q35 machine type since its inception,
we just did not add it implicitly.

This is already possible with qemu, and actually already happening with
q35 machines and a specified watchdog since q35 already includes a
watchdog we do not include in the XML. In order to express such
posibility multiple watchdogs need to be supported.
