The bug tracker here https://bugs.centos.org/view.php?id=10930 shows Severity as major. I'm new to CentOS administration. In your experience how fast do those bugs get patched?lixdeg wrote: Yes. This issue seems to be not that important to them.
I found a post from 17th of May, where someone already posted a workaround to this issue.
Not many CentOS under virtualization. Or not many hosts with AES cpu flags.
Also did you follow the solution here https://bugs.centos.org/view.php?id=10930#c26705 to fix it?
I have two XenPV VM's, one running CentOS and one running CloudLinux, and after the 6.8 update I'm getting the exact same errors as you on both of them.
