What version of QEMU is this? The initialization is O(n^2) because the guest initializes one device at a time, so you rebuild the FlatView first with 0 devices, then 1, then 2, etc. This is very hard to fix, if at all possible. However, each FlatView creation should be O(n) where n is the number of devices currently configured. Please check with "info mtree -f" that you only have a fixed number of FlatViews. Old versions had one per device. Paolo
