Special:Badtitle/NS1198:Checkpointing and live migration/13/en

It is a critical requirement that file system at the moment of restore must be identical to the file system at the moment of checkpointing. If this requirement is not met, depending on the severity of changes, the process of restoration can be aborted or the processes inside a VE can see this as an external corruption of open files. When a VE is restored on the same node where it was checkpointed, it is enough to not touch the file system accessible by the VE. When a VE is transferred to another node it is necessary to synchronize the VE file system before restore. vzctl does not provide this functionality and external tools (i.e. rsync) are required.
