Currently interrupt priorities are set to 0 (highest) at the very beginning of the guest execution which is not correct and makes the guest produce random interrupt error messages such as: "Interrupt 0x1001 (real) is invalid, disabling it". This also prevents interrupt states from correct migration.
This initializes priority to 0xFF as the emulated XICS does.
