Description of problem:
When installing the kernel-rt package without the kernel-rt-kvm package, I get the following warnings:
depmod: WARNING: /lib/modules/3.10.0-666.rt56.585.el7.x86_64/kernel/drivers/gpu/drm/i915/gvt/kvmgt.ko needs unknown symbol gfn_to_memslot

The problem is that the kvmgt.ko module needs symbols exported by kvm.ko, which is provided by kernel-rt-kvm.
The consequence of this problem is that the user will be unable to load kvmgt if kernel-rt-kvm is not installed. If kernel-rt-kvm is installed afterwards, depmod -a needs to be run again otherwise the user will still be unable to load kvmgt.
I think the best solution is to include kvmgt in the kernel-rt-kvm package. Although I don't know if anyone will ever be using kvmgt under the RT kernel or if it works at all under the RT kernel.
Version-Release number of selected component (if applicable): kernel-rt-3.10.0-666.rt56.585.el7.x86_64
How reproducible:
Steps to Reproduce:
1. Install the kernel-rt package without kernel-rt-kvm
