problem with 64-bit guests on VirtualBox after latest updates

[Andre Robatino]

After the latest batch of F12 updates, VirtualBox won't run 64-bit
guests anymore, giving the following error message:

VT-x/AMD-V hardware acceleration has been enabled, but is not operational.
Your 64-bit guest will fail to detect a 64-bit CPU and will not be able
to boot.
Please ensure that you have enabled VT-x/AMD-V properly in the BIOS of
your host computer.

I have the Virtualization package group installed.  Unloading the
kvm_amd module allows 64-bit guests to run again.  Can someone with the
Virtualization group installed who hasn't applied the Dec. 1 updates
check if kvm_amd is loaded?  Is this a Fedora bug?  If so, which
component, so I can report it?
