Comment 8 for bug 1637601

Problem:

We setup 2 Ubuntu KVM host with the same mount point and try to migration the guest between 2 HOST. The migration is success, the guest appear on other Host after the migration but it shows some I/O error on the guest.
<...>

On the first host, run this

root@micro:~# virsh migrate --live --domain microg5 qemu+ssh://10.33.10.115/system --verbose --undefinesource --persistent --timeout 60
Migration: [100 %]

The guest appear on other HOST:

root@tiny:~# virsh list --all
Id Name State

2 tinyg1 running
3 tinyg2 running
5 tinyg4 running
6 tinyg5 running
7 tinyg6 running
9 tinyg3 running
12 microg5 running <<< this guest is from HOST "Micro"

Checking status of the guest, I can see this error....

root@microg5:~# dmesg |tail -20
