Virtualization Use Cases – Cost Reduction

Consolidation :

• Redeploy multiple discrete systems/domains onto a single multi-core processor

Benefits:– Cost effective : bill-of-material, power

– Preserve investment : software re-use

– Improved hardware utilization

– Flexibility

Virtualization Use Cases – Reliability & Protection

Sandboxing :

• Add untrusted software to a system, e.g. operator applications

• Run GPL based software in isolation• Run test software safely• Isolate security-sensitive tasks :

access rights control, rule definitions, key management, …

High availability

• active/standby configuration without additional hardware

Virtualization Use Cases – Flexibility & Scalability

Run legacy software / OS on LinuxAdd functionality to existing system by dropping in a VMUse different versions of the Linux kernelBetter resource management• Allocation of physical CPUs / control CPU load• Create/destroy VMs as neededMaps well to split workload• e.g. control plane, data planeIn-service upgrade

Shift from Separate Boxes to Modules that Support Applications• Simplification• Reduced cost• Free up space• Redundancy

Locomotive Chassis: Networking Based32-bit• ARM® Cortex Ax-series• Choose processor based on interface need

64-bit• ARM® Cortex A53-series• Could supplant x86-based applications

To date we have targeted KVM for these modules

Locomotive Chassis: Processing BasedVariant #1• Intel® BayTrail Processor (2014)

• “Starter Set”

Variant #2• Intel® Broadwell Processor (2015)

• “High Test”

To date, we have used Xen for virtualization solutions

Linux ContainersDon’t Shoot the Messenger…• Being considered for ARM®-based

solutions where operating systems could share a common kernel

• Performance on 32-bit becomes important

Xen Processor Support

• Currently both Intel-based processors we are using are not supported by the Xen set we are using

• Expansion extremely important to us – need to be able to add processors in the future and have them join the same pool of resources

Local Management of Guests

• Need rules-based capability for HyperVisor to automatically restart guests, or even start a different guest

• HyperVisor to Guest handshaking / status• Better pool management – HyperVisor can

coordinate with others in the pool, and make smarter decisions including migration of guests where it makes sense

Standardized Imaging

• Probably something easy… but…• Need non-UUID fixed ways to move entire

HyperVisor images from one module to another• Includes pooled pairs being able to be swapped

out and have pools maintained (network-based rules)
