We need it for our work. Hey Christian, I knew you do a lot of testing with BookE, I didn't know you used KVM there. Good to know it's working for you. In that case I withdraw my question. BookE KVM has not been too much trouble, but some things come up that really need testing before patching, so a QEMU HV implementation would be good to have (I mean QEMU running the host). mpe has a hardware but probably no time$ to do much testing (especially of other peoples' untested patches). So having that would help keep kernel support going. Thanks, Nick
