What CRtools is

CRtools is an utility to checkpoint/restore process tree. Unlike checkpoint/restore implemented completely in kernel space, it tries to achieve the same target operating in user space. Since the tools and overall concept are still under heavy development stage there are some known limitations applied

  1. Only pure x86-64 environment is supported, no IA32 emulation allowed.
  2. There is no way to use cgroups freezer facility yet.
  3. No network or IPC checkpoint/restore supported.
