cloudlet with ”-m“ option goes wrong

[t00197857]

thanks for your last reply。In addition，I‘m very intrested in your study。I have succeeded in making such a overlay without “-m“，but with the “-m” option（I want to test free memory ），it went wrong。 I don‘t understand this。 Does this option really support ，or maybe something is wrong with me。（The precise.raw comes from yours）The log is as below：

Besides，I have a question about the issue about profilng for chunks in order。 “This part (in FUSE file system) tells you disk & memory access order when the VM is launched. Base on this information, you can create your own profiler“. Do you have a specific method about how to create the profiler If the access order information is known by us？Thanks very much。
