Instead of manually building a list of all options from BDRVQcowState
|
|
|
9ae3a8 |
values just reuse the options that were used to open the image.
|
|
|
9ae3a8 |
qcow2_open() won't fully use all of the options in the QDict, but that's
|
|
|
9ae3a8 |
okay.
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
This fixes all of the driver-specific options in qcow2, except for
|
|
|
9ae3a8 |
lazy-refcounts, which was special cased before.
