The shortest end-to-end path to your first ZSvirt VM: install the management node from the ISO, initialize hosts, storage, network, and image storage, create a VM from an ISO or a ready-to-use system image, and verify connectivity — all in about 30 minutes.
ZSvirt TeamBroadcom has confirmed that public VDDK downloads are gone and that the VDDK is not a customer entitlement. If you already have a copy it still works — but rebuilding an environment or starting a new project will hit a wall. Here is what changed, and why the window to migrate is open now.

ZSvirt TeamThis article explores the design, implementation, and benefits of the shortcut key system introduced in the ZSvirt virtualization platform. It addresses common user challenges such as long operation paths and low efficiency, detailing how the system assigns shortcuts based on high-frequency scenarios, core functions, and mainstream conventions. The piece covers the technical architecture, including event listeners and command registration, and provides an overview of supported shortcuts for resource lists, task windows, and global search.
ZSvirt TeamZStack offers an architecture where 99% of tasks are executed asynchronously, enabling a single management node to handle hundreds of thousands of physical servers, millions of virtual machines, and tens of thousands of concurrent tasks. This article explores the motivation, design, and implementation of ZStack's asynchronous architecture.
Frank ZhangTo tackle challenges such as significant operations overhead, duplication of effort, testability that microservices usually face, ZStack encompasses all services in a single process called management node, building an in-process microservices architecture.
Frank ZhangZStack offers a lock-free architecture built on queues, allowing tasks to control their parallelism level easily from 1 (synchronized) to N (parallel). This article explains how ZStack avoids distributed locks using consistent hashing and memory-based work queues.
Frank ZhangZStack, with a versatile plugin system, allows features to be implemented as plugins (both in-process or out-of-process) which can not only extend ZStack's functionality, but also hook into business logic to change default behaviours.
Frank ZhangEvery ZStack service is stateless. Making services highly available and scaled out can be as easy as starting redundant service instances then load balancing them. This article explains how ZStack builds a stateless distributed system using consistent hashing and a centralized message bus.
Frank ZhangTags in ZStack not only help users aggregate resources but also control behaviors of the software. ZStack has a complete specification defining category, form, and usage of tags for users, plugins, and third-party software.
Frank ZhangWith a workflow engine, every step in ZStack wrapped in individual flow can be rolled back on error. This article explains ZStack's workflow engine that breaks monolithic business logic into fine-grained, rollbackable steps for system integrity.
