Paths for external devices (well, so far only vTPM) are not
|
||||
stored in the status XML. Therefore, we need to regenerate them
|
||||
after we've been restarted and reconnecting to a running domain.
|
||||
Otherwise these will remain NULL which may later lead to a NULL
|
||||
dereference.

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.
