restore in namespace |
- |
having images taken from live app, need to restore them inside newly created namespace. For PID we'd have to provide our own init, for NET -- setup some veth.

TCP socket migration with changed IP |
xemul@ |
it might make sense to migrate a tcp connection on a box with changed IP address _if_ both boxes are NAT-ed to the destination. We will then have to go to NAT box and fix the conntracks, but this might make sense.

Apply-images mode |
xemul@ |
Think about ability to take images and apply them to a living task(s). E.g. -- repopulate fdtable according to data from image. Another use-case -- when doing partial migration we'll need to modify one part to switch from pipes to sockets
|
crtools |
Modify restored resources run-time |
xemul@ |
Need (probably) some way to alter what is being restored. Usage example -- change the IP address of sockets from task above.

partial migration |
- |
migrate some tasks while proxying IPC to existing others (pipes->sockets, etc.)

Shared objects (mm/fs) support |
avagin@ |
Now we have the kcmp syscall and can do it. The first candidate is mm sharing, as we do know, that MySQL does so sometimes.

Paranoid dumping and restoring |
- |
Make paranoid checks for what we dump. E.g. pgid being valid (withing session) and fds drained from parasite are valid
|
crtools |
Smart paths resolution |
- |
Need a way to resolve paths to overmounted files. There are two ways: 1. Move mounts, that overlap the desired path temprarily. 2. When creating a new mount pre-open an fd keeping the mountpoint. Later, do accurate path resolve and call openat() on proper mountpoint fd

Iptables |

This is easy. Need to run ipdables-save and iptables-restore
|

Multiple namespaces |
- |
Need to handle the cases when more than one namespace of one type exists and dump them properly

migrate script |

It's not complex, but openvz-like migrate scripts should exists

Validate .img files |

For a given set of image files check, that they are in "restorable" shape

Restore a process tree |
Larisa Markeeva |
Need to restore any process tree, which could be created with help PR_SET_CHILD_SUBREAPER and CLONE_PARENT. Processes can share other resources clone(2). Look at session02
