I can consistently reproduce this using the SPDK NVMe controller (https://review.spdk.io/gerrit/c/spdk/spdk/+/7617/14) as the vfio-user device and migrating a VM (-enable kvm -cpu host
is required). This may be related to https://lists.gnu.org/archive/html/qemu-devel/2021-07/msg04194.html
Need to retest with branch https://github.com/oracle/qemu/tree/vfio-user-rfc1.1.

I tested this branch and didn't reproduce this issue, before this commit it can happen very frequently by rebooting a VM.
Thanks @changpe1 , I should check to see whether it fixes the migration repro.
@john-johnson-git QEMU seems to be adding duplicate regions and KVM doesn't like it:
