Charm++ parallel programming system

Hi,everyone,

I install BigSim in a virtual machine ,and the OS is ubuntu.

I got a exception in BigNetSim as below for detail.

------------- Processor 1 Exiting: Called CmiAbort ------------
Reason: Invalid machineInfo on disk file!

The exception seem to be thrown from the bigsim_read.C file.

What's mean ?  Who can help and explain to me? 
What should I do?

Thanks.
Qin
