pass "" instead of NULL (not setting is good too).
However we can get problems here. Disk detaching treats source
as ids. Fortunately disk detaching is not supported for cdroms
yet and for hard disks we can not get empty source - this is prohibitited
by xml parsing code.

vz: fix vzCheckUnsupportedDisks format checks for cdroms
Current version of the function does not check format of cdroms at all.
At the same time prlsdkGetDiskInfo give hints that cdroms always
have format VIR_STORAGE_FILE_RAW. So fix vzCheckUnsupportedDisks.
About structure of checks. As we don't have means to store format
in SDK we always have only one format in every situation. So instead
of setting boolean let's get allowed format instead and finally compare
it to the requested. This structure of checks seems stable to me
because we have only one format in every situation.

virmock.h: Introduce VIR_MOCK_CALL_STAT
There is some magic going on when it comes to stat() or lstat().
Basically, stat() can either be a regular function, an inline

the same as the inline func. Don't ask why is that, just read the
documentation in sys/stat.h and make sure you have a bucket next
to you. Anyway, currently there will not be both stat and __xstat
symbols at the same time, as one of them gets overwritten to the
other one during compilation. But this is not true anymore once
we start chaining our mocking libraries. Therefore we need a

Note: This change fixes xlconfigtest failures when the old

determine if it is the old or new qemu so it can properly set

Both virGetLastError and virGetLastErrorMessage call virLastErrorObject method
that returns a thread-local error object. However, if a direct call to malloc

pointer. This isn't the case with virGetLastErrorMessage that also treated it
incorrectly as no error, but returned the literal "no error".
This patch tweaks the checks in the virGetLastErrorMessage function, so that
if virLastErrorObject failed, it returned "unknown error" which is equivalent
