An overview of the Verizon Cloud Architecture and what Xen Features are in use. This will include planned features as well. A major part is the goal of Quality of Service (QoS) in all areas. This includes CPU, Memory, Network, and Disk. Also the network is based on level 2 so is more flexible. We provide a GUI as well as an API (the GUI uses the API for all tasks). Another design goal is to correctly handle scale. We also plan to offer full access to the guest console (VGA and serial). The tool stack is distributed and runs as guests on Xen.
Enhancements to Xen/Qemu required to support seamless import of VMWare guests include: emulation of devices available in VMWare, support for VMWare tools back-door, PCI bridge emulation enhancements, as well as fine-grained control over the placement of PCI devices, CPUID, and PCI hole size.
