System emulation

Incompatible changes

  • The ARM 'virt' board now has a second PCI MMIO region of 512G size. It is useful for large devices like ivshmem and video cards. However, old Linux kernel builds with LPAE disabled are incapable to handle such controller. In this case, older guests will no longer successfully detect the PCI controller. In order to keep those guests running, it is possible to disable this region by adding "highmem=off" machine option.
