This is where for_thibaut points at for me:
commit bf6830e2416f67571ee2e7196f3625725adec170

vhost: set the correct queue index in case of migration with multiqueue
When a live migration is started the log address to mark dirty pages is
provided
to the vhost backend through the vhost_dev_set_log function.
This function is called for each queue pairs but the queue index is wrongly
set:
always set to the first queue pair. Then vhost backend lost descriptor
addresses
of the queue pairs greater than 1 and behaviour of the vhost backend is
unpredictable.
The queue index is computed by taking account of the vq_index (to retrieve
the
queue pair index) and calling the vhost_get_vq_index method of the backend.

hash might change if I find any issues.
If this is not what you see, you need to re-fetch the tag.
Please let me know whether this tag works for you.
