Thanks for the reply. Sorry for the typo in the earlier mail. I have PV-HVM of CentOS 7 & I need to convert it to PV kernel. Basically here I am trying to see whether my PV_HVM kernel is vulenrable to this issue given in the following link http://seclists.org/oss-sec/2015/q3/212 In the above link, it was mentioned that the PV kernel is not vulnerable to this bug, but HVM is. It didnt say anything about PV-HVM. Can you please help me in this regard?
