Hi,
2 weeks ago I also opened a ticket. I tooks me 10 days to persuade a TAC to simulate same situation in their LAB, At first they did not want is as they dont have it in bug list :-)
From my point of view it seems to be problem with LIS. 12.1.4.1 version has LIS 3.5 included but 14.1.2.1 has version 3.1 (Hyper-V says this information). Probably they changed Kernel from
12.1.4.1 version cat /etc/centos-release
CentOS release 6.6 (Final)
to
14.1.2.1 version cat /etc/centos-release
CentOS Linux release 7.3.1611 (Core)
but forgot to update LIS
Currently Im still waiting for update from TAC
I´ll post here result once I get it
