Hi Jeageun, you should take a look at util/m5/README.md for an explanation of how the m5 utility works and how it should be used in different environments. It looks like it's trying to use the instruction based mechanism to call into gem5, and that won't work in KVM. In KVM, you have to use the magic address based mechanism. That's all spelled out in that README. There are also instructions there for building the utility if your version is too old and doesn't have the updates reflected in that document. The older m5 utility would have to be recompiled to use a different mechanism, where with the new version you can select what mechanism to use from the command line.
