− | ZDTM stands for zero-down-time-migration. It's test suite developed for testing how OpenVZ live migration works. We use this test suite for checking how crtools do their job. The suit consists of many small atomic tests -- each puts a process into some "state" (opens a file, maps a memory segment, puts data in a pipe, etc.), then asks to be checkpointed and restored. The in checks that the "state" was preserved (file is still open, memory is still mapped, pipe contains what was put into it). | + | ZDTM stands for zero-down-time-migration.
