Broadcom Working On VMware Zero-Copy Buffer Sharing Between VMs And Hypervisor

Interesting feature work for VMware virtualization on Linux now being pursued by Broadcom is to support zero-copy buffer sharing between the VM(s) and host hypervisor, which would equate to an efficiency and performance win...

Why this matters
Why now

The continuous demand for greater efficiency and performance in virtualized environments drives ongoing optimization efforts.

Why it’s important

This development could significantly enhance the performance and efficiency of virtualized Linux workloads, particularly crucial for high-demand applications and data centers.

What changes

VMware virtualization on Linux may become more performant and resource-efficient for I/O operations between VMs and the hypervisor.

Winners
  • · Broadcom
  • · VMware users
  • · Data center operators
  • · Cloud providers
Losers
  • · Less optimized virtualization platforms
Second-order effects
Direct

Reduced CPU overhead and memory footprint for I/O operations in VMware on Linux.

Second

Improved consolidation ratios and lower operational costs for virtualized Linux environments.

Third

Enhanced competitive positioning for VMware in high-performance Linux workloads against other virtualization or containerization platforms.
