When working CRIU uses two directories to keep the data in.
This is the one specified with the
-D|--images-dir $path option. If not given CRIU uses current working directory. This is where all images are put.
Prev images directoryEdit
When using the memory changes tracking facility it's important to tell CRIU where images from previous run are. This is done by specifying the path with the
Remember, that the path given should be relative to the images directory, e.g. like this
# criu dump --images-dir ./images-1 --track-mem # criu dump --images-dir ./images-2/ --prev-images-dir ../images-1 --track-mem
Symlinks in paths of absolute paths will not work as well unfortunately.
