Xen not running hvms (but CPU supports vmx)

Question

I am trying to create an HVM DomU on a Centos5 system. When I run the command

virt-install -n build1a -r 2048 --vcpus=4 --os-type=linux --hvm --disk path=/dev/guests/build1a --network=bridge:eth0 --vnc --vncport=1 --location http://mirror.centos.org/centos-5/5.6/os/x86_64/

It immediately fails with

ERROR    Host does not support virtualization type 'hvm' 

I am running a Core-i5 and here is the output of egrep '^flags.*(vmx|svm)' /proc/cpuinfo

flags       : fpu tsc msr pae cx8 apic mtrr cmov pat clflush acpi mmx fxsr sse sse2 ss ht syscall nx lm constant_tsc ida arat pni vmx est ssse3 cx16 sse4_1 sse4_2 popcnt lahf_lm

Any ideas would be greatly appreciated.

It turns out that I didn't have virtualization enabled in the bios.
