I was able to figure out the problem. After testing three types of servers/workstation, I was able to figure out what the issue is. It is a combination of both hardware and software. The older Intel-V technology used in PCs made in 2009 seem to work with Centos 6.x/KVM with a guest running Mcafee endpoint encryption(MEE). Newer Intel-V technology will give you a black screen when running MEE on a windows 7 guest and having Centos 6.x/KVM as the host. Here is the workaround. You need to use the elrepo repository and enable the kernel-ml in /etc/yum/repos.d and use a newer kernel (3.4). KVM has been built into the kernel since 2.6.20 and the kmods are based on the kernel version. Using a newer kernel will allow MEE to come up. I am not sure if the Centos 6.x kernel base will ever have MEE working on a guest when the host is Centos 6.x/KVM.
