Guest code may want to call functions that have variable arguments. To do so, we either need to compile with -mno-sse or enable SSE in the VCPUs. As it should be pretty safe to turn on the feature, and -mno-sse would make linking test code with standard libraries difficult, we choose the feature enabling.
