Xen PV Performance Status and Optimization Opportunities

In this session we examined the Xen PV performance on the latest platforms in a few cases that covers CPU/memory intensive, disk intensive and network intensive workloads. We compared Xen PV guest vs. HVM/PVOPS to see whether PV guest still have advantage over HVM on a system with state-of-the-art VT features. KVM was also compared as a reference. We also compared PV driver performance against bare-metal and pass-through/SR-IOV. The identified issues were discussed and we presented our proposal on fixing those issues.
