Virt Manager: Warning KVM not available

Post by jmazzella » 2017/01/06 03:48:13

I have a newly installed CentOS 7 with Virtualization Host selected during install. When I attempt load a VM using Virt Manager, there is an error stating Warning KVM not available....

I found some internet resources that listed the packages that were needed and to use lsmod | grep kvm to see if the modules are loaded (which the appear they are not? ) see below.... ( I also ran a command that seemed to confirm that the cpu's are VM compatible.)

Not sure where the issue is ... perhaps not all software is installed?

Thanks in advance for your help.

Regards,
-John

I found the issue. It was a new Dell R710 with the cpu virt disabled in the BIOS.
