about pcie-hot-plug on aarch64

[Jaze Lee]

Hello,
    We run Openstack Stein on arm. It  runs nova-compute(use libvirt
as virt driver) on arm host. We found when built with disks (use ceph
rbd) on arm hosts, the vm can not attach all disk correctly. For
example, built with six disks, the vm may attach three disks. No
obvious error can be fond in nova-compute, libvirt. We compare aarch64
and x86, find when detach disk, the dmesg of the vm's os is different.
May be the pciehg parameter is different?

Did anyone met the problem?  Or some suggestions?


x86:
Nothing at all
