Oh, i see what you mean. Existing naming practice would suggest naming
it -no-xenhv or just -no-xen
All these '-no-XXX' args are getting a little silly though. I'd rather
tell QEMU what I *do* want, than what I don't want. A generic arg
'-accelerator none|xen|kvm|kqemu' might be worth considering in the future.
That can be a separate discussion from these patches though - we should
just follow the -no-XXX naming for now to minimize diffs
