For a long time we've masked out VIR_DOMAIN_BLOCK_COPY_SHALLOW if
|
|
|
d76c62 |
there's no backing chain for the copied disk to simplify the code.
|
|
|
d76c62 |
|
|
|
d76c62 |
One of the refactors of the block copy code caused that we no longer
|
|
|
d76c62 |
update the 'flags' variable just the local copies. This was okay until
|
|
|
d76c62 |
in ccd4228afff we started storing the job flags in the block job data.
|
|
|
d76c62 |
|
|
|
d76c62 |
Given that we modify how we call qemu we also should modify @flags so
|
|
|
d76c62 |
that the correct value is recorded in the block job data.
