Subject: [PATCH 2/2] fix: Fall back to cached local ds if no valid ds found
|
||||
(#4997)
|
||||
|
||||
Rebooting an instance which has finished VMware guest
|
||||
customization with DataSourceVMware will load
|
||||
DataSourceNone due to metadata is NOT available.
|
||||
|
||||
This is mostly a re-post of PR#229, few differences are:
|
||||
1. Let ds decide if fallback is allowed, not always fall back
|
||||
to previous cached LOCAL ds.
|
||||
2. No comparing instance-id of cached ds with previous instance-id
|
||||
due to I think they are always identical.
|
||||
|
||||
Fixes GH-3402
|
||||
|
||||
(cherry picked from commit 9929a00580d50afc60bf4e0fb9f2f39d4f797b4b)
