示例1: snapshot

def snapshot(self, instance, image_id):
"""Create snapshot from a running VM instance
:param instance: instance to be snapshotted
:param image_id: id of image to upload to
Steps involved in a XenServer snapshot:
1. XAPI-Snapshot: Snapshotting the instance using XenAPI. This
creates: Snapshot (Template) VM, Snapshot VBD, Snapshot VDI,
Snapshot VHD
2. Wait-for-coalesce: The Snapshot VDI and Instance VDI both point to
a 'base-copy' VDI. The base_copy is immutable and may be chained
with other base_copies. If chained, the base_copies
coalesce together, so, we must wait for this coalescing to occur to
get a stable representation of the data on disk.
3. Push-to-glance: Once coalesced, we call a plugin on the XenServer
that will bundle the VHDs together and then push the bundle into
Glance.
