Proxmox

Notes for building, maintaining, and troubleshooting Proxmox VE clusters and VMs/CTs.

Core topics

• Storage: ZFS, LVM-thin, Ceph (if used), backups, pruning
• Networking: bridges, VLANs, firewall rules, SDN
• Virtualization: VM vs LXC, virtio, CPU types, PCIe passthrough
• Backups: Proxmox Backup Server, schedules, retention, restores

Common workflows

• Create a VM template (cloud-init)
• Add VLAN-aware bridges
• GPU/iGPU passthrough checks (IOMMU, vfio, ROMs)
• Snapshot + rollback before upgrades

Useful pages

Tip: Include exact commands + the expected output (or “what good looks like”).
