# PCMan File Manager ## Identification [[Inter-process Communication|IPC]] is the general process-to-process communication category; [[D-Bus|D-Bus]] is a specific message-bus implementation. [[PCMan File Manager|PCManFM]] is a Linux file manager. [[QEMU|QEMU]] provides emulation/virtualization; [[SPICE Protocol|SPICE]] provides remote display and device redirection; [[QCOW2|qcow2]] is QEMU's copy-on-write disk format; [[Virtual Machine Manager|virt-manager]] is a graphical libvirt/QEMU manager. ## Notebook evidence - [[Scanned_20260730-1659#PDF page 12 — D-Bus, QEMU, SPICE, qcow2, and virt-manager|PDF page 12: D-Bus, QEMU, SPICE, qcow2, and virt-manager]] — D-Bus is a message bus for local inter-process communication; PCManFM is a lightweight Linux file manager. QEMU supplies machine virtualization/emulation, SPICE supplies remote-display and USB-redirection facilities, qcow2 supplies copy-on-write virtual disks, and virt-manager supplies a management GUI. QEMU’s documentation describes qcow2’s metadata and snapshot-oriented design, while the project’s support page points users toward virt-manager for a graphical workflow. ## Relationships and overlays The source places this record in an evidence cluster with [[D-Bus|D-Bus]] · [[Inter-process Communication|Inter-process Communication]] · [[QCOW2|QCOW2]] · [[QEMU|QEMU]] · [[SPICE Protocol|SPICE Protocol]] · [[Virtual Machine Manager|Virtual Machine Manager]]. The occurrence contributes to the notebook's larger model of [[Identity Continuity|identity continuity]], [[Device Sovereignty|device sovereignty]], and [[Continuity Architecture|continuity architecture]]. ## Evidentiary status and open leads Recover the intended guest OS, QEMU version, USB-redirection target, and the ambiguous grab-key notation. ## Source - [[Scanned_20260730-1659|Scanned_20260730-1659]]
