libvirt currently silently allows <timer
name="kvmclock"/> and some
other timer tags in the guest XML definition for timers that do not
exist on non-x86 systems. We should not silently ignore these tags
since the users might not get what they expected otherwise.

This would render previously as valid accepted domains invalid, e.g. on
s390x using kvmclock: As long as the user does not specify the "present"
attribute the domain starts without error since qemus cpu parameter is
not extended.
The feedback of all other archs would be good to have.
@Daniel: What's your opinion?
