It seems we did not follow the structure with 'stdio_handler', but adding it either right after 'dump_guest_core' or at the end of file would be better than squeezing it between rpc entries.As Michal suggested in: https://www.redhat.com/archives/libvir-list/2018-August/msg01693.html max_queued and state_lock_timeout both refer to the same area, so I put it here :)
My point was that the position in qemu.conf does not match the grouping in libvirtd_qemu.aug So if it's related to max_queued, it should also be in the rpc_entry group in the aug file. Jano
