Unfortunately, this patch breaks migration under TCG because the XIVE
source flag is not updated on the target side. KVM is not impacted
because the emulated sources are not used. This needs to be addressed
in a v2.
That said, even without this patch, TCG migration is broken. some CPUs

When an interrupt has been handled, the OS notifies the interrupt
controller with a EOI sequence. On a POWER9 and POWER10 systems using
