Which code exactly assumes that all memory slots are writable? > Do you want to create read only memory slots for kvm tool? What KVM tool currently does is copy the kernel into guest memory and run it from there. An idea raised recently was instead of copying it we should mmap it into the memory to reduce footprint. This is why I'm looking into adding a read only memory slot. The KVM code doesn't have to know it's read only. -- Sasha. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
