Example Problem Description
- Bug: https://bugzilla.redhat.com/show_bug.cgi?id=12345
- Affects: Operating Systems Affected
symptoms
### Run packstack behind a proxy
workaround
The installer fails to apply Puppet with the following error:
Error: Could not set 'present' on ensure: Network is unreachable - connect(2) at /var/tmp/packstack/f879707404cb448bb629827308990223/modules/packstack/manifests/provision/glance.pp:12
The installer cannot download the demo image because the puppet-glance module does not support proxy.
symptoms
### Nova instance provision fails when host is not mapped to any cell
- Bug: https://bugzilla.redhat.com/show_bug.cgi?id=1480326
- Affects: RHEL 7
- Installation: packstack
workaround
You can either disable the demo provisioning or use a local image.
- Disable the demo provisioning
# packstack --allinone --provision-demo=n
- Use a local image
# curl http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img -o /root/cirros-0.3.5-x86_64-disk.img
# packstack --allinone --provision-image-url=/root/cirros-0.3.5-x86_64-disk.img
The instance fails to start with the following error:
> Setup is incomplete.: HostMappingNotFound: Host '<hostname>' is not mapped to any cell
The host is not mapped to any cell:
[root@host ~(keystone_admin)]# nova-manage cell_v2 list_hosts

Manually run cell_v2 discover_hosts
[root@host ~(keystone_admin)]# nova-manage cell_v2 discover_hosts --verbose
[root@host ~(keystone_admin)]# nova-manage cell_v2 list_hosts
