I've set-up bifrost which is spawning two VMs to test with.  I'm using the xena branch

for both bifrost and ironic.  Bifrost sets these VMs up as whole-disk-images.  I've

undeployed one VM and trying to deploy the same VM by using the default kickstart

file and a RHEL7 ISO file but I'm not having any success.  Could you suggest what

configuration changes are expected in this case to get this to work? What would you expect

deploy-interface and instance-info to look like?

BTW And I've applied portions (changes to cache_ramdisk_kernel() only) of the patch for https://review.opendev.org/c/openstack/ironic/+/827924.
