Subject: [PATCH] qemu: Always re-detect backing chain
|
|
|
9119d9 |
|
|
|
9119d9 |
Since 363e9a68 we track backing chain metadata when creating snapshots
|
|
|
9119d9 |
the right way even for the inactive configuration. As we did not yet
|
|
|
9119d9 |
update other code paths that modify the backing chain (blockpull) the
|
|
|
9119d9 |
newDef backing chain gets out of sync.
|
|
|
9119d9 |
|
|
|
9119d9 |
After stopping of a VM the new definition gets copied to the next start
|
|
|
9119d9 |
one. The new VM then has incorrect backing chain info. This patch
|
|
|
9119d9 |
switches the backing chain detector to always purge the existing backing
|
|
|
9119d9 |
chain and forces re-detection to avoid this issue until we'll have full
|
|
|
9119d9 |
backing chain tracking support.
