It'd be great if qemu could autodetect this, i.e. presumably use
getconf(PAGE_SIZE) for this.
As has been explained to me by the qemu ppc people, autodetecting this
is wrong because this way qemu will start with different configuration
on different hosts, and the virtual machines will be unpredictable
non-migratable. I don't know how important this is, though - probably
being able to start in the first place is more important.
