Subject: libxc sr xl migration debug
|
||
|
|
|
||
|
|
xl: fix description of migrate --debug
|
||
|
|
|
||
|
|
xl migrate --debug used to track every pfn in every batch of pages.
|
||
|
|
But these times are gone. The code in xc_domain_save is the consumer
|
||
|
|
of this knob, now may enable verification mode.

v03:
|
||
|
|
- adjust to describe what --debug would do when the code which
|
||
|
|
consumes this knob is fixed.
|
||
|
|
v02:
|
||
|
|
- the option has no effect anymore
