Andrija Panic commented on CLOUDSTACK-8353:
-------------------------------------------
Guys, any progress on this ? We are on 4.5.1, and 1 major customer is regularyy
affected with BSOD on Windows 2008 R2.
Not sure what to do, or what a workarround would be - they have many, many
servers, and its impossible to quickly upgrade to Windows 2012 R2 (which works
fine)
Any ideas, comments, please ?
