# OpenNebula OpenNebula is a technology or product recorded in [[Scanned_20260730-1706|Scanned_20260730-1706]]. In the reconstruction, OpenNebula is an open-source cloud and virtualization management platform spanning enterprise, private, hybrid, and edge infrastructure (OpenNebula documentation). ## Historical and Technical Context [[rEFInd|rEFInd]] is a UEFI boot manager that presents operating-system choices at startup and can participate in network boot workflows ([rEFInd documentation](https://www.rodsbooks.com/refind/)). [[GRML Rescueboot|grml-rescueboot]] integrates rescue ISO images into [[GNU GRUB|GRUB]], allowing recovery media to be booted without first writing it to removable media. [[OpenNebula|OpenNebula]] is an open-source cloud and virtualization management platform spanning enterprise, private, hybrid, and edge infrastructure ([OpenNebula documentation](https://docs.opennebula.io/7.2/)). “LightMBP” likely names a lightweight MacBook Pro host; “NVMANnode” appears to be a local node name. ## Role in Scanned_20260730-1706 The page is designing a **rescue-capable multi-boot/cloud node**: keep ISO recovery media available in GRUB, consider rEFInd for UEFI selection, and associate the host with an OpenNebula-managed environment. ## Notebook Evidence - [[Scanned_20260730-1706|Scanned_20260730-1706]], PDF page 10: Boot managers and cloud node. **Evidentiary status:** The page occurrence and transcription are notebook evidence. Technical identification follows the source reconstruction’s cited research. Co-occurrence does not by itself prove ownership, deployment, or a direct operational relationship. ## Relationships and Overlays On the cited page or pages, OpenNebula appears with [[GNU GRUB|GNU GRUB]], [[GRML Rescueboot|GRML Rescueboot]], [[rEFInd|rEFInd]]. These are page-level or reconstruction-level relationships, not automatic claims of dependency. ## Cross-Notebook Significance This note overlays the QEMU, UTM, VDI, VMware, Citrix, and hybrid-cloud material in [[Scanned_20260730-1802|Scanned_20260730-1802]]. The new source adds the local provisioning, image-format, cluster, or operator-control layer beneath that earlier infrastructure map. ## Missed Signals and Open Leads “CI” may mean cloud infrastructure, continuous integration, or a local project label. “inode fs?” is too fragmentary to resolve. ## Sources - [[Scanned_20260730-1706|Scanned_20260730-1706]], especially PDF page(s) 10. - `Scanned_20260730-1706.pdf`, cited as a plain archival filename; the PDF is not linked from `wiki-notes`. - External research citations used for identification remain preserved in the source reconstruction. - [rEFInd documentation](https://www.rodsbooks.com/refind/) - [OpenNebula documentation](https://docs.opennebula.io/7.2/)
