How can I ensure all physical and logical cores are counted by VDSM within RHEV 3?

Solution Verified - Updated 2013-08-05T14:33:59+00:00 -

Issue

After upgrading vdsm or RHEV-H, RHEV-M shows a lower number of CPUs for a given host.
How can I ensure all physical and logical cores are counted by VDSM within RHEV 3?
I have hyperthreading enabled which should show double the number of CPU cores but RHEV only shows the number of physical cores. Why?
CPU Count on Host wrong, prevents migration

Environment

Red Hat Enterprise Virtualization Manager (RHEV-M) 3.0, 3.1
Red Hat Enterprise Virtualization Hypervisor (RHEV-H) 6.2.20120423 and later
