On October 24th StorPool storage will participate in the CloudStack European User Group Day in London. The event is organized by our friends from ShapeBlue and will bring together the Apache CloudStack community. This time the visitors will have the chance to enjoy an all-day event, full with exciting and useful sessions. StorPool’s team is happy to share that we will also contribute to the CloudStack community with a speaker at the event. Our CloudStack Developer, Slavka Peleva, will present the session “Storage based snapshots for KVM VMs in CloudStack.”
Storage-based Snapshots for KVM VMs in CloudStack
Currently, in CloudStack live snapshots of KVM VMs are supported only through libivirt/QCOW snapshots. However, other primary storage providers can implement (atomic) snapshots. At StorPool’s session, Slavka Peleva will present how StorPool integrated this functionality in CloudStack and what are its benefits and use cases.
Slavka will present a significant enhancement to the CloudStack/KVM VM snapshot functionality. Now, a whole VM snapshot is supported only with qcow2 internal snapshots. This has two major drawbacks – the VM is suspended during the process and only qcow backend is supported – so no advanced storage provider can be used.
StorPool has designed and implemented an alternative VM snapshot framework for CloudStack/KVM employing the underlying storage provider capability to create snapshots. This new approach delivers VM snapshots with minimal impact on the working VM and works with all storage providers. We have also implemented and extension to the default storage provider so it can operate in the new framework.
StorPool provides a primary CloudStack storage solution. We integrated our storage solution deeply with CloudStack and has a native driver in the host OS, which provides block devices in /dev/storpool/volname as raw disk images for qemu/KVM. The integration offers the functionality to manage volumes and snapshots directly in the storage system via its API. If you are curious to learn more about how to build a cloud with StorPool and CloudStack, meet us in London.
