Virtualization

Design Nextcloud with TrueNAS SMB without corrupting metadata: compare separate datasets, external SMB storage, direct access, change detection, and backups.

Make a Proxmox virtual disk appear in Windows Setup by matching the VirtIO driver to the VM bus, loading it from a second ISO, and verifying storage settings.

Prepare and clone an ESXi VM that uses a USB dongle, separate passthrough issues from stale HBR filters, and reconnect hardware safely.

Learn what the vSphere On-disk Metadata Analyzer checks, when to use it, why the datastore must be quiescent, and when VOMA repair is too risky.

Safely diagnose and remove stale vSphere Replication hbr_filter entries that can prevent a cloned VMware virtual machine from powering on.

Diagnose an idle Windows VM that feels slow on ESXi by correlating CPU Ready, Co-Stop, storage latency, memory reclamation, network, RDP, and guest evidence.

Diagnose a TrueNAS VM that cannot see a new VMDK, distinguish the boot disk from data disks, and choose between a lab setup and HBA passthrough.

Trace vSphere Replication network errors from the correct ESXi VMkernel interface to the target VR server, verify ports, and avoid blind restarts.

Learn why eight vCPUs cannot appear as two faster cores, how Access 32-bit uses CPU and memory, and how to right-size a Windows VM with evidence.
