virt-manager vs ZStack

virt-manager is a desktop interface for managing virtual machines through libvirt, chiefly for KVM, with support for Xen and LXC as well. It connects to local and remote hosts and displays live performance and resource-use statistics for running domains. Setup wizards help create domains and assign resources and virtual hardware, while an embedded VNC and SPICE viewer provides a graphical guest console. The interface also manages host virtual networks, storage pools, and network interfaces. Companion command-line tools handle provisioning, cloning, and editing virtual machines. virt-manager runs on Linux and OpenBSD hosts, supports both guest architectures, and includes snapshots and GPU acceleration. Installation options listed include Fedora, Debian, Gentoo, and OpenBSD packages, plus a source release. It is distributed under the GNU General Public License; current releases are GPG signed, with verification instructions. Documentation and a FAQ are available, support questions go to GitHub Discussions, and bug tracking is on GitHub.

ZStack Cloud is self-hosted infrastructure software for managing compute, networking, and storage in data centers. The product range spans private cloud, virtualization, AI infrastructure, hyperconverged infrastructure, storage, networking, container cloud, and multi-cloud management. ZCF combines compute, storage, networking, containers, and security in a software-defined private-cloud platform with a unified portal, operations, and identity management. It manages hosts, disks, images, and snapshots, and supports scheduling and elastic scaling. ZStone provides block, file, and object storage; Zaku manages Kubernetes clusters and containers alongside virtual machines. ZStack Cloud Enterprise integrates with Alibaba Cloud and offers a RESTful API, backup and recovery options, high-availability policies, and a UI migration service for mainstream Windows and Linux cloud hosts. Listed free plans provide full features for three months for ZStack ZSphere or one year for ZStack Cloud. ZStack describes its products as enterprise infrastructure, including for private clouds in organizations' own data centers. ZLR enterprise disaster recovery is marked as coming soon.
