Libvirt storage jobs. This project includes renaming storage volume(storage pool, snapshot,etc), moving volume from one pool to another, the capability support for storage driver (like virsh capabilities for the hypervisor drivers, e.g. what pool types it supports, what volume types each pool type supports, even may what operations/APIs the pool type support, ...etc). If these ones(or portions of them) are deserved to do, we should add them to our wiki of GSOC 2013. Students will submit their applications for these ideas at April 22nd. Could anyone please review these ideas(or portions of them)? Thanks very much in advance. -- Thanks Harry Wei -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
