It's not supported for the malta/mips64r2 combination you are trying to
use. It's clearly possible that it is supported for mips64r6, but it's a
different instruction set, so you can't run a standard Debian
distribution on it.

Lixing mentioned virtualization. In that case it is indeed supported
like on other mips64r5 CPUs. For that you need to use add the -enable-kvm
option to the qemu command.
