The domain startup process is split into multiple phases. One of
|
|
them is preparing the domain (at that point live) XML, private
|
|
data, various paths, etc - see qemuProcessPrepareDomain(); the
|
|
other prepares the host - see qemuProcessPrepareHost(). It's
|
|
obvious that the domain XML preparation function must be called
|
|
before the host preparation function (e.g. the host preparation
|
|
might try to create a file which path is generated in the domain
|
|
preparation phase). Nevertheless, let's document this
|
|
expectation.
