Hi! I have downloaded the latest p.haul from https://github.com/xemul/p.haul and have a first tried and need some helps. My steps are 1. wrote a simple program #include <stdio.h> #include <sys/types.h> #include <unistd.h> int main() { int i=0; while(1) { printf("count %d (%d)\n", i++, getpid()); fflush(stdout); sleep(1); } } And compile to an executable file 'aa'. 2. Setup a machine A with CRIU 2.0 3. Setup a machine B same as machine A 4. Run 'criu service -daemon' on both machine A and B 5. Run 'p.haul-wrap service' on machine A 6. Run "setsid ./aa < /dev/null &> /dev/null &" on machine B 7. Run "p.hau-wrap client <machine A IP> pid <pid of aa> On the machine A, I got the log below. It looks like the process cannot be restored on the machine A.
