September 2014 Windows Updates Issue on Hyper-V hosts?
I performed some End of Month updates this weekend which froze the login screen on my Hyper-V hosts, no mouse movement, Ctrl+Alt+Del did nothing, non responsive. We were forced to perform a hard reset on the machines that is currently hosting around 100 VMs. I am glad we were able to recover from this malfunction but I am having issues trying to determine what exactly caused this issue.
Has anyone else seen this issue on Windows Server 2012 R2 platform and where should I start my investigation?
I have not noticed any issues on my physical servers, workstations, etc. except on the Hyper-V hosts.
