Subject: [PATCH] blkdeviotune: fix bug with saving values into live XML
|
|
|
9119d9 |
|
|
|
9119d9 |
When you updated some blkdeviotune values for running domain the values
|
|
|
9119d9 |
were stored only internally, but not saved into the live XML so they
|
|
|
9119d9 |
won't survive restarting the libvirtd.
