I am embarrassed to say that I missed it in the trash dump that is
my inbox.  Apologies Manfred and thanks for your quick response.
Manfred's response certainly explained the problem clearly.

Yes, the 20.04 problem is why I started down the road of using FAI
to build the VMs.  I was having problems getting xen tools to build
bootable 20.04 domu.  Likely my own problem, but I am a lot more
familiar with FAI then xen-tools.  Thanks for helping get moving
again.  In spite of the fact that I wear glasses I often find that
4 eyes is not enough for me to see what is in front of my face.

Thanks,

Bill
