Title:
boot from image(create a new volume) lost image property
Status in OpenStack Dashboard (Horizon):
Expired
Bug description:
when we create a instance by boot from image(create a new volume), if the
image has one or more property, it will boot without the property.
for example, we add a property 'hw_qemu_guest_agent=yes' on image ubt1204,
Property | Value |
+--------------------------------+--------------------------------------+
| Property 'hw_qemu_guest_agent' | yes |
| checksum | 2823c8bf0336349b23f20fb75ec60626 |

then,we create a instance on horizon by boot from image(create a new volume),
in the libvirt.xml of this instance, it doesn't contain below config:
<channel type="unix">
<source
path="/var/lib/libvirt/qemu/org.qemu.guest_agent.0.instance-000000a4.sock"
mode="bind"/>
<target type="virtio" name="org.qemu.guest_agent.0"/>
</channel>
and if we create a instance by boot from image, the libvirt.xml
contain the above config
I read the code and found :
if we create a instance by boot from image(create a new volume), image_ref in
instance is null, below is the code to create libvirt.xml:
def to_xml(self, context, instance, network_info, disk_info,
image_meta=None, rescue=None,
block_device_info=None, write_to_disk=False):
# We should get image metadata everytime for generating xml
if image_meta is None:
(image_service, image_id) = glance.get_remote_image_service(
context, instance['image_ref'])
image_meta = compute_utils.get_image_metadata(
context, image_service, image_id, instance)
# NOTE(danms): Stringifying a NetworkInfo will take a lock. Do
# this ahead of time so that we don't acquire it while also
# holding the logging lock.
network_info_str = str(network_info)
LOG.debug(_('Start to_xml '
'network_info=%(network_info)s '
'disk_info=%(disk_info)s '
'image_meta=%(image_meta)s rescue=%(rescue)s'
'block_device_info=%(block_device_info)s'),
{'network_info': network_info_str, 'disk_info': disk_info,
'image_meta': image_meta, 'rescue': rescue,
'block_device_info': block_device_info})
conf = self.get_guest_config(instance, network_info, image_meta,
disk_info, rescue, block_device_info)
xml = conf.to_xml()
if write_to_disk:
instance_dir = libvirt_utils.get_instance_path(instance)
xml_path = os.path.join(instance_dir, 'libvirt.xml')
libvirt_utils.write_to_file(xml_path, xml)
LOG.debug(_('End to_xml instance=%(instance)s xml=%(xml)s'),
{'instance': instance, 'xml': xml})
return xml
image_ref is null so it can't generate full libvirt.xml
