Virtualisation (KVM host)
Running guest operating systems is a first-class use of WebGen, not an add-on. The kernel includes KVM host support; QEMU runs the guests with near-native speed. iproute2 creates bridge and tap devices so guests get real network access.
For GPU/PCI passthrough the kernel ships VFIO with the IOMMU built in — add intel_iommu=on (or amd_iommu=on) to the kernel command line to arm it, then bind a device to vfio-pci.
The intended lifecycle: boot the live ISO → install to disk → use that install as a master system that runs your daily-driver OSes as guests.
