Hi!

Is there any design- or development-work done yet?
If not -- i would try to implement this feature and would submit a possible patch?

Greetings!

#4 Updated by Ruben S. Montero over 7 years ago

Hi,

We've not started the development yet. Summary of the design for this feature:

  • Depending where the snapshot is stored, they can be internal (stored within the disk) or external (stored as a separated file/dev)
  • Depending what it is saved, they can be disk, memory (RAM & CPU) or system (disk & memory)
  • Our high level requirements is to be able to snapshot a VM and to "revert" to the state. The snapshots would be independent, multiple snapshots of the same VM could be instantiated once.
  • The support for the different types of snapshots depends on the hypervisor and the storage technology used to support the VM disk images.
  • Another requirement for us is to present and homogeneous as possible functionality across technologies.

Initially we've decided to go for disks snapshots, pretty much as the snapshots that can be found in EC2. We will use the hypervisor functionality when available to produce consistent disk snapshots...

Feedback more than welcome!

Finally, we'll go for both system and disk snapshots.

Are the one.vm.snapshotcreate and one.vm.snapshotrevert calls for the "system" snapshots ie. VM state snapshots? Are you going to have separate call / driver actions for disk snapshots?

Yes

Yes, disk snapshots will be TM based

#8 Updated by Carlos Martín about 7 years ago

Improvement to consider: The DispatchManager::snapshot_create method could call LibVirtDriverKVM (in case the VM vmm is kvm) and check if all the VM disks use DRIVER=qcow2, to return a request failure before the operation is attempted by the drivers.
