Hm.  Actually all the problems I've had I've traced to environments (bad
network setup for one, device permissions for another).  I finally got a
maverick xen host in a working environment - and vmbuilder -ec2 worked
there.

What does /proc/devices on your host show?  What sort of storage setup
do you have?  The 'Is device-mapper driver missing from kernel?' is
odd, and presumably comes from grub in the chroot.  It almost sounds
like your host is multipathed.  What does 'df -h' and 'mount' on the
host show?

Does a regular 'vmbuilder xen ubuntu' work for you?
