Hi, oVirt provides VM Pools: https://www.ovirt.org/documentation/admin-guide/chap-Pools.html but the VMs in pool are designed to be stateless and so, on that user case, the user specific data should stored on an external (not on the VM disk) storage area like an NFS or SMB/CIFS share mounted inside the VM at user login time. Probably you can achieve something closer to your initial idea relying on oVirt-CinderLib integration over a capable SAN or a Ceph storage. https://ovirt.org/develop/release-management/features/storage/cinderlib-integration.html Please be aware that in 4.3 cinder-lib integration is still a "tech-preview" grade feature and the design of the whole solution will probably require a relevant integration/configuration effort on your side to correctly achieve copy-on-write behaviour on storage side. > > Fabio > _______________________________________________ > Users mailing list -- users@ovirt.org > To unsubscribe send an email to users-le...@ovirt.org > Privacy Statement: https://www.ovirt.org/site/privacy-policy/ > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/users@ovirt.org/message/3XITFLEJDICOFY3KQTBHFASBF7KANJCV/ >
