Description Jaroslav Henner 2013-08-15 17:34:30 EDT

Description of problem:
config_drive_cdrom = false should ensure the config drive will be HDD, not a CD ROM, but it is ineffective. Nova creates VM with 

    <disk type="file" device="cdrom">
      <driver name="qemu" type="raw" cache="none"/>
      <source file="/var/lib/nova/instances/3eeb598a-6871-49bf-8016-fb519531e296/disk.config"/>
      <target bus="ide" dev="hdd"/>
    </disk>

cloud-init doesn't detecting this disk, fallbacks to network metadata discovery and because of bug BZ#984311, it keeps outputting
2013-08-15 17:22:37,764 - url_helper.py[WARNING]: Calling 'http://169.254.169.254/2009-04-04/meta-data/instance-id' failed [85/120s]: url error [[Errno 113] No route to host]
for several minutes upon boot.

Version-Release number of selected component (if applicable):
openstack-nova-common-2013.1.3-1.el6ost.noarch
openstack-nova-compute-2013.1.3-1.el6ost.noarch

How reproducible:
1/1

Steps to Reproduce:
1. openstack-config --set /etc/nova/nova.conf HYPERV config_drive_cdrom false
2. openstack-config --set /etc/nova/nova.conf DEFAULT config_drive_cdrom false
3. for svc in /etc/init.d/openstack-*; do $svc condrestart; done
4. boot an instance
5. observe the log, or check whether the config disk is an sr0
/dev/disk/by-label/config-2 ../../sr0

Actual results:
disk is CDROM

Expected results:
disk is HDD (/dev/vdb)

Additional info:
Setting urgen because it is kinda regression and it causes workaround of other bug ineffective.

Comment 1 Jaroslav Henner 2013-08-16 05:10:49 EDT

ndipanov adivced to set

openstack-config --set /etc/nova/nova.conf DEFAULT config_drive_format vfat

this did the trick. Config drive is now back a HDD.

Comment 2 Alan Pevec 2013-08-16 06:36:06 EDT

So we need a relnote?

Comment 3 Alan Pevec 2013-08-16 07:36:30 EDT

Nikola will change default in nova-dist.conf so we don't need RHOS relnote.
For upstream I've added a relnote in https://wiki.openstack.org/wiki/ReleaseNotes/2013.1.3#Known_Issues_and_Limitations

Comment 6 Omri Hochman 2013-08-26 08:08:43 EDT

Verified  openstack-nova-2013.1.3-2 (puddle 2013-08-20.1): 

Followed the bug steps - after I set debug=True in nova.conf -> it allowed to observe the Instance creation XML in compute.log, that include:
disk type="file" device="disk"
