I have the same problem on CentOS 6.3 :-
/proc/cpuinfo shows only 16 VCPUs.
It should have 24 VCPUs based on the HW config:- Hyperthreaded 2 x Intel
Xeon E5-2620
uname -a says :-
3.7.9-1.el6xen.x86_64
xen-hypervisor-4.2.1-4.el6.x86_64
xen-runtime-4.2.1-4.el6.x86_64
kernel-xen-release-6-4.noarch

kernel-xen-firmware-3.7.9-1.el6xen.x86_64
xen-4.2.1-4.el6.x86_64
xen-licenses-4.2.1-4.el6.x86_64
kernel-xen-3.7.9-1.el6xen.x86
grub.conf looks like this :-
