Storage & Performance
The installers prepare local VM storage and, for performance-sensitive paths, tune CPU and device placement.
LVM
Depending on topology, the installer can create LVM-backed storage for:
- DL root/data
- DA root/data
- AIO
- Sensor VM images/data
Before execution, confirm the selected block devices and existing volume groups. Do not assume an unallocated disk is safe to reuse without reviewing the host.
CPU and NUMA
The active installers can calculate or apply CPU placement where appropriate. AIO + Sensor and DP paths may use CPU affinity to keep performance-sensitive workloads aligned with the intended hardware layout.
SR-IOV and PCI passthrough
Before enabling direct device assignment:
- enable IOMMU in BIOS
- inspect IOMMU groups
- confirm the NIC is dedicated to the target VM role
- verify the host will retain management connectivity
- plan how the device is restored if rollback is required
