Is there any interest in it? For Sparc32 this could be possible, the page table structures are not unlike i386 ones. Given the death of Sparc32 distros I don't think there would be much interest. On Sparc64 there are no in-memory structures for MMU, instead page table entries are pushed into TLB when needed. I think kqemu would have to mess with the OS page structures or install its own TLB handler. As Sparc architecture is much better on virtualisation than x86, it should be possible to port kvm instead.
