At least the capability name should be consistent with the command name.
Since the capabilities are qemu specific there is no reason to have the
discrepancy here.
I've googled some sources on the plural of 'zero' and looks like that
indeed 'zeros' is more commonly used. At any rate. I don't really care
which you actually choose for the XML name and variables, but the
capability name should be spelled as qemu spells it.
