Rockstar🎓
Top SchoolColin Xu is a Principal Member of Technical Staff with eight years’ experience specializing in GPU and virtualization software stacks across Windows and Linux. He architects and implements GPU virtualization (GVT-g, SR-IOV), device virtualization (vfio, virtio), and CPU/hypervisor solutions (KVM, QEMU, HAXM), focusing on cloud and IoT use cases. At AMD he leads GPU virtualization efforts for cloud providers, and at Intel he contributed to the widely used Intel HAXM project, fixing multi-CPU support and stability issues in VMX handling. His background spans kernel-mode graphics drivers, display and power management, and complex cross-component features like multi-pipe virtual memory switching for hypervisors. Known for advanced debugging skills and a pragmatic systems mindset, he often bridges driver, firmware and user-mode components to deliver robust virtualization solutions. Based in Shanghai, he pairs deep low-level expertise with a track record of shipping production-ready, large-scale virtualization features.
