Update the domain XML that will be used when I<domain> is later
|
||||||
|
started. The I<xml> argument must be a file name containing
|
||||||
|
the alternative XML, with changes only in the host-specific portions of
|
||||||
|
the domain XML. For example, it can be used to change disk file paths.
|
||||||
|
|
||||||
|
The managed save image records whether the domain should be started to a
|
||||||
|
running or paused state. Normally, this command does not alter the
|
||||||
|
recorded state; passing either the I<--running> or I<--paused> flag
|
||||||
|
will allow overriding which state the B<start> should use.
