Hi,
After cloning the repository when I am trying to run the following command getting the password error.
test@ubuntu-big:/home/ubuntu/elijah-provisioning$ fab install
[localhost] Executing task 'install'
[localhost] run: egrep '^flags.*(vmx|svm)' /proc/cpuinfo > /dev/null
[localhost] Login password for 'test':
[localhost] Login password for 'test':
[localhost] Login password for 'test':
[localhost] Login password for 'test':
Even though I am entering the correct password, its not accepting the password. I tried with different users but getting the same error.
Can you please help me out if I am missing something. ?
Thanks

Hello。 I have a question about early start。As the paper “Just-in-Time Provisioning for Cyber Foraging” said,“We make a reasonable attempt to order the chunks according to a profiled access pattern
computed offline”,and I studied the code under this project,I haven’t found the corresponding code about how to make chucks in order。maybe I'm not careful enough,can you help me?
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:

Hi, I just start learning about your project so this is a very basic question. I was wondering whether it is possible to export a base VM image according to the base VM raw data you provide. I just tried to use command cloudlet export-base [the location I want to put my *.img file][the name I want to use] but a get an error 'Cannot find matching base disk'. I have added the base VM raw data in the list so I get confused how to fix it. Thank you for your answer.
The fluid server backend is not available on the provided link:
https://storage.cmusatyalab.org/cloudlet-app/fluid-server-bin32.tar.gz
Is there any chance on providing this?
