Kuburitswa kweiyo CRIU 3.18 (Checkpoint uye Restore In Userspace) toolkit yakadhindwa, yakagadzirirwa kuchengetedza uye kudzoreredza maitiro munzvimbo yemushandisi. Iyo Toolkit inobvumidza iwe kuchengetedza iyo mamiriro eimwe kana boka remaitiro, uye wobva watangazve basa kubva panzvimbo yakachengetwa, kusanganisira mushure mekugadzirisazve system kana pane imwe sevha, pasina kutyora yakatosimbiswa network yekubatanidza. Iyo kodhi yeprojekiti yakagoverwa pasi peGPLv2 rezinesi.
Nzvimbo dzekushandisa tekinoroji yeCRIU dzinosanganisira kuve nechokwadi kuti OS inotangazve pasina kukanganisa kuenderera kwekuita kwemaitiro akareba, Kurarama kutama kwemidziyo yakasarudzika, kukurumidza kutangwa kwemaitiro anononoka (unogona kutanga kushanda kubva kuhurumende yakachengetwa mushure mekutanga), kuita kernel. inogadziridza pasina kutangisa masevhisi, nguva nenguva kuchengetedza mamiriro ekufamba kwenguva refu.computing mabasa kuti utangezve basa kana pakaitika tsaona, kuenzanisa mitoro pamanodhi mumasumbu, kudzokorora maitiro pane mumwe muchina (forogo kune iri kure system), kugadzira snapshots ye mashandisirwo emushandisi panguva yekushanda kwekuongorora pane imwe sisitimu kana kana zvichifanira kudzima zvimwe zviito muchirongwa. CRIU inoshandiswa mumidziyo manejimendi masisitimu akadai seOpenVZ, LXC/LXD uye Docker. Shanduko dzinodiwa kuti CRIU ishande dzinosanganisirwa muLinux kernel huru.
Mukuburitswa kutsva:
- Zvinokwanisika kushandisa CRIU pasina midzi kodzero.
- Yakawedzerwa tsigiro yeSIGTSTP chiratidzo (inopindirana kumbomira chiratidzo icho, kusiyana neSIGSTOP, chinogona kugadziriswa nekuregeredzwa).
- Yakawedzerwa "--skip-file-rwx-cheki" paramende kuti usvetuke mvumo yefaira yekutarisa (r/w/x) panguva yekupora.
- Yakawedzera rutsigiro rweIP_PKTINFO uye IPV6_RECVPKTINFO sarudzo.
- Kune mapuratifomu eARM, rutsigiro rwe Hardware breakpoints rwakaitwa.
- Yakawedzera kuchengetedza optimization kune yakanyanya sparse ghost mafaera (-ghost-fiemap).
