Subject: [PATCH] migration/ram: Accelerate the loading of CSV guest's
|
||
|
|
encrypted pages
|
||
|
|
|
||
|
|
When memory encryption is enabled, the guest memory will be encrypted with
|
||
|
|
the guest specific key. The patch introduces an accelerate solution which
|
||
|
|
queued the pages into list and load them togather by COMMAND_BATCH.
