Comment 5 for bug 1825976

So i was tracking down promotion job failures and reached to this bug, This bug is affecting all ovb jobs in both upstream master check[1] and master promotion jobs[2], issue started happening with https://review.opendev.org/#/c/630644/43 merged as placement iptables rules are not there[3], still a doubt as PS37 has job passing but those logs are deleted, someone from nova can confirm this. Marking the bug as critical and promotion blocker.
