I have a volume group that I migrated from 1 physical drive to two
RAID 0 drives. Looking at the disk access it appears that I have no
stripe. All data access seems to be on the first drive. How do I
re-configure the volume group to stripe accross the two physical
drives?

I think you've to recreate the Logical Volume(s) using the stripes option (-i)

Not really the answer I wanted. I assumed that the default was for LVM
to stripe and by adding bot disks to the volume group before migrating
it of the physical extent I would be OK. I migrations can loose stripe
then surely that is an issue?
The Volume was created as part of a xen server virtual machine install
so I have limited control over initial LV creation parameters.
