Glossary

Agent (kestrel): In-guest process that acts as PID1 in default initramfs mode and proxies OpenAPI calls over vsock.
Bridge (vbr0): Linux bridge used to connect VM tap devices to the host network.
CIDATA: Volume label for NoCloud seed images used by cloud-init.
Cloud-init: Standard for VM initialization; Volant supports NoCloud via seed image.
Deployment: A named set of identical VM replicas managed by the orchestrator.
Init modes: default/custom/none — control PID1 behavior in initramfs builds.
Manifest: JSON document describing plugin runtime, boot media, devices, and more.
Rootfs: A bootable filesystem image derived from an OCI image (ext4/xfs/btrfs).
Initramfs: Compressed RAM filesystem used as initial userspace.
Tap: TUN/TAP device used to provide Ethernet to a microVM.
Vsock: Virtio socket channel used for host↔guest communication without Ethernet.
VFIO: Linux kernel framework for PCI passthrough; used for GPUs/devices.
