Because of past qemu bugs we set this to default off and required a workaround to enable it. However these issues appear to be fixed, and we should enable this by default for people (with the ability to turn it off if it's causing crashes in their environment). Metacloud/Cisco has been running default this way the entire time without issue. Change-Id: I4545cc99683d311c41c8d6d8dc9787ea6ec6cbc9

upgrade:
|
|
- |
|
|
Nova now defaults to using the live snapshot feature of libvirt
|
|
when taking snapshots. This was previously disabled by default due
|
|
to crashes on load seen with older libvirt versions. It has been
|
|
used in production by many clouds, and appears stable in real
|
|
world environments. If you see crashes of guests during snapshots,
|
|
you can disable this with the ``disable_libvirt_livesnapshot``
|
|
config value in ``[workarounds]``.
