Generation prompt

Near-white technical zine aesthetic with black ink, one strong red accent (#cc0000), sparse 2005 web sensibility, philosophical but legible. Create a polished wide infographic visual for "Being a Xen hypervisor" about Life as a Xen hypervisor. Context: Treat the reader as a peer. Give a full Xen overview: hypervisor versus dom0, domU, driver and stub domains, PV/HVM/PVH execution, CPU scheduling, memory translation and ballooning, I/O split drivers, grant references and event channels, xenstore, PCI passthrough, IOMMU isolation, live migration, observability, security boundaries, and operational failure modes. Do not over-center grants or ballooning; present them as parts of the larger architecture.. Key points to visualize: Domain model and privilege boundaries; Boot modes and guest execution; CPU scheduling and vCPU topology; Memory ownership and translation; I/O paths and split drivers; Device assignment and DMA isolation; Live migration and state transfer; Operations, observability, and failure modes. Use concise labels only; avoid paragraphs and tiny text. Leave the detailed explanatory copy to the surrounding HTML page.
