[pve-devel] [PATCH manager v8 4/4] ui: MachineEdit with viommu ComboBox

Markus Frank m.frank at proxmox.com
Wed Jan 24 10:49:18 CET 2024


Added a proxmoxKVComboBox for selecting a vIOMMU implementation for a
VM. If i440fx is selected, a hint tells that q35 is required for Intel vIOMMU.

The UI also needs to parse the new machine parameter as PropertyString.
