[Self] Snapshots

[pdonias]

• Create snapshot:

  • self users can snapshot their VMs
  • a snapshot uses all the types of resources even if it was created by an admin
  • a self user can't snapshot if there aren't enough resources available
  • an admin is always able to snapshot even if it uses more than the available resources
  • a "snapshot with memory" uses the same resources as a standard snapshot

• Delete snapshot:

  • self users can only delete their snapshots
  • deleting a snpashot releases its resources

• Delete VM:

  • deallocate the VM's resources
  • deallocate the snapshots' resources

• Revert:

  • a self user can revert any snapshot on their VMs
  • reverting a snapshot updates the quotas
  • if reverting a snapshot means using more than the available resources, then the revert fails
  • an admin is always able to revert even if it uses more than the available resources
  • the VM keeps its original resource set (if any) through the reverting process
  • properly re-alloc the snapshot's IP addresses

• "Snapshot before": (moved to client side, thus behaves as normal snapshot)

  • the "snapshot before" feature tries to create a snapshot (and consume some resources) (chore(xo-web,xo-server): move "snapshot before" feature to the client #4893)
  • if there aren't enough resources to "snapshot before", the whole revert operation fails (chore(xo-web,xo-server): move "snapshot before" feature to the client #4893)
  • an admin is always able to "snapshot before" (chore(xo-web,xo-server): move "snapshot before" feature to the client #4893)

• Remove user from resource set:

  • all their permissions on VMs are revoked (fix(xo-server/self): remove ACLs when user is removed from resource set #4874)
  • all their permissions on snapshots are revoked

• Add a VM to a resource set:

  • its snapshots are also added to the resource set, except the backup-related ones
  • all the quotas allocations are forced because this is always done by an admin

• Remove a VM from a resource set

  • all the resource set's subjects have their permissions on the VM revoked
  • all the resource set's subjects have their permissions on the VM's snapshots revoked
  • the VM's resource usage is removed from quotas
  • the VM's snapshots' are removed from the resource set
  • the VM's snapshots' resource usages are removed from the quotas

• Share a VM within a resource set

  • "share" its snapshots (ie the RS subjects get permissions on them) except the backup-related ones

• Convert to template

  • self-users can't convert their VMs
  • when an admin converts a VM to a template, the VM is removed from the resource set

• self-users can create a VM from a snapshot

• self-users can export a snapshot

• Recompute all limits:

  • take snapshots into account but
  • ignore backup-related snapshots

Should not ignore self user snapshot but ignore admin snapshots
