mumu

mumu is a hobby hypervisor-ish. mumu can be a good resource to learn virtualization, hypervisors and KVM right now. In the future, who knows, it may become a real hypervisor.

hello world

it's very easy to run virtual machines under mumu.

1. Create partition vm.

cd examples/vm/hello_world
make

2. Run mumu

cd examples/mumu
g++ helloworld.cpp -lpthread
./a.out

3. Output:

KVM version 12
vcpu init success
