+static uint32_t vmport_cmd_get_time(void *opaque, uint32_t addr)
+    CPUState *env = opaque;
+    struct timeval tv;
+    gettimeofday(&tv, NULL);
+    env->regs[R_EAX] = tv.tv_sec;
+    env->regs[R_EBX] = tv.tv_usec;

FWIW, this is incorrect. You are presenting the host's version of wall clock time, not the guest's version.
