Proposals for this user

* KVM I/O Performance on Large Storage Systems

An examination of KVM I/O performance in three large storage environments (direct-attached storage with multiple disk arrays, remote storage, and a typical storage cloud), identification of key performance issues and attributes in each of those environments, and our recent results in addressing those performance issues and optimizing I/O performance for KVM in those environments.
