ASF subversion and git services commented on CLOUDSTACK-1191: ------------------------------------------------------------- Commit bef3a2edb7f23035a7d397d2d68caf6cecc0f497 in branch refs/heads/rbd-snap-clone from Wido den Hollander <w...@widodh.nl> [ https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;h=bef3a2e ] CLOUDSTACK-1191: rbd: Use cloning for deploying templates instead of a copy RBD format 2 supports cloning (aka layering) where one base image can serve as a parent image for multiple child images. This enables fast deployment of a large amount of virtual machines, but it also saves spaces on the Ceph cluster and improves performance due to better caching. Qemu-img doesn't support RBD format 2 (yet), so to enable these functions the RADOS/RBD Java bindings are required. This patch also enables deployment of System VMs on RBD storage pools. Since we no longer require a patchdisk for passing the boot arguments we are able to deploy these VMs on RBD. > Implement RBD snapshotting, backups and cloning > ----------------------------------------------- > > Key: CLOUDSTACK-1191 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1191 > Project: CloudStack > Issue Type: Improvement > Security Level: Public(Anyone can view this level - this is the > default.) > Components: KVM, Snapshot, Storage Controller, Volumes > Affects Versions: 4.2.0 > Reporter: Wido den Hollander > Assignee: Wido den Hollander > Labels: ceph, kvm, libvirt, rbd > Fix For: 4.2.0 > > > The current RBD implementation lacks these features. > The new storage subsystem will allow us to implement these features as > described on the wiki: > https://cwiki.apache.org/confluence/display/CLOUDSTACK/RBD+improvements+based+on+new+Storage+subsystem -- This message is automatically generated by JIRA.
