Hi Ruby:

I couldn't use your whole changeset since it introduced a different issue. With your patch, I was seeing the

following error and it never reached the code creating squashfs.img as a directory. So I removed the patch

and only applied the pxe_util.py changes in cache_ramdisk_kernel() and I've made further progress.

| last_error | Failed to prepare to deploy: Cannot validate driver deploy. Some parameters were missing in node's instance_info. Missing are: ['root_gb'] |

Is this root_gb a new requirement? More background: At the moment, I don't have baremetal devices and I'm starting my work by

using VMs bifrost created for me. Also I'm using the xena branch of bifrost/ironic.

Ironic folks:

I'm trying to spawn a RHEL7 image using a kickstart file and having issues with stage2 file.
First I used bifrost to initially setup a couple of VMs. (There is no openstack/glance).
I'm now using one of those VMs to boot up with RHEL7. I changed the VM config
with the following:

| deploy_interface | anaconda
| instance_info | {'kernel': 'http://myip:8080/RHEL7/vmlinuz', 'ramdisk': 'http://myip:8080/RHEL7/initrd.img', 'image_source': 'http://myip:8080/RHEL7/initrd.img', 'stage2': 'http://myip:8080/RHEL7/squashfs.img', 'ks_cfg': 'http://myip:8080/RHEL7/ks.cfg.template', 'ks_template': 'http://myip:8080/RHEL7/ks.cfg.template'}

ironic.conf changes I made are as follows:
enabled_deploy_interfaces = direct,ramdisk,anaconda
[anaconda]
default_ks_template = file:///etc/ironic/ks.cfg.template

The error I'm getting is as follows:
$ baremetal node show testvm1 --field last_error
| last_error | Deploy step deploy.deploy failed with IsADirectoryError: [Errno 21] Is a directory: '/httpboot/4e41df61-84b1-5856-bfb6-6b5f2cd3dd11/LiveOS/squashfs.img'.
Tail end of traceback is as follows:
