I had been running VirtualBox-5.0-5.0.10_104061_el7-1.x86_64 against kernel-3.10.0-229.14.1.el7.x86_64 with out issue.  After installing the latest kernel mentioned by Etienne, and attempting to rebuild the vboxdrv modules, I had similar failures.  Afterward, I attempted to upgrade to VirtualBox-5.0-5.0.12_104815_el7-1.x86_64, I discovered the libdevmapper issue noted in the previous post which prevented the newer version from installing.

Unfortunately, the testing build for EL7: https://www.virtualbox.org/download/testcase/VirtualBox-5.0-5.0.11_104721_el7-1.x86_64.rpm, does not install due to the same libdevmapper issue.  I had hoped maybe the devmapper issue was introduced in builds between the latest testbuild and the release build for 5.0.12, no such luck.

The CentOS and Oracle Linux public yum repo's latest version is device-mapper-libs-1.02.107-5.el7.x86_64.  Is that in the pipeline for release to SL7 soon?

I am confused.  As I thought I understood the current EL situation, Red 
Hat owns CentOS and distributes EL full source, per GPL, Linux, etc., 
licenses, through CentOS for all non-RH rebuilds (e.g., Oracle) to use 
(sans Red Hat logos, services, etc.).  In this case, two questions:

(1) Is Fermilab/CERN not funded well enough to have the same 
rebuliding/packaging resources as Oracle just to rebuild from the RH 
CentOS sources, and thus is delayed in production binary (RPM) release 
compared to Oracle?  Both Fermilab and CERN are funded through their 
respective governments that support fundamental research.

(2) If (1) is true, during the interval before the "current" RH 
production release is a SL release, can one simply use the CentOS or 
Oracle RPMs (e.g., in this case, 
device-mapper-libs-1.02.107-5.el7.x86_64.rpm) to maintain compatibility 
with Oracle licensed-for-free products (e.g., VirtualBox)?
