ManageIQ vs virt-manager

ManageIQ is a free, open-source cloud management platform for discovering and managing connected infrastructure. It inventories virtualization, container, network, and storage systems, maps relationships, and tracks changes. Its service catalog lets users order resource bundles and manage their lifecycle through policy, compliance, delegated operations, chargeback or showback, and retirement. ManageIQ scans virtual machines, hosts, and containers without agents, including foreign and uncooperative VMs. For optimization, it captures utilization metrics and supports identifying unused systems, right-sizing recommendations, capacity planning, and what-if scenarios. The agentless virtual appliance can run standalone or in a federated deployment. Other deployment options include appliances on cloud and virtualization platforms, a Docker monolithic container, and podified deployments on Kubernetes and OpenShift. A REST API uses HTTP requests and responses with JSON. Listed providers include AWS, Azure, Google Cloud, IBM Cloud, Kubernetes, OpenStack, Red Hat, and VMware, but supported operations vary by provider. Docker and Vagrant downloads are intended for proof-of-concept and non-production use.

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.
