Libvirt bindings for Node.js®.

Example Usage

``typescript
import libvirt, {
DomainBuilder,
domainDescToXml,
domainDescFromXml,
} from "@unraid/libvirt";

const uri = process.env.LIBVIRT_URI || "qemu:///system";
const hypervisor = new libvirt.Hypervisor({ uri });

(async () => {
await hypervisor.connectOpen();

// parse xml template
const template = await domainDescFromXml("...");

// build new domain description
const domain = new DomainBuilder()
.fromTemplate(template)

.setName("test1")
.setUUID("148d0864-2354-4c27-b82c-731bdd3f320c")

.addDisk({
type: "file",
device: "disk",
driver: { name: "qemu", type: "qcow2" },
source: { file: "/home/leon/test1.img" },
target: { dev: "vda", bus: "virtio" },
})

.addInterface({
type: "network",
source: { network: "default" },
mac: { address: "52:54:00:8e:c6:5f" },
model: { type: "virtio" },
})

.build();

// define and boot domain
const xml = domainDescToXml(domain);
await hypervisor.domainCreateXML(xml);

// list active domains
const activeDomains = await hypervisor.connectListAllDomains(
libvirt.ConnectListAllDomainsFlags.ACTIVE
);

// log active domain names
const activeDomainNames = await Promise.all(
activeDomains.map((domain) => hypervisor.domainGetName(domain))
);
console.log(activeDomainNames);

await hypervisor.connectClose();
})();
