Subject: [PATCH 1/8] libxl: fix crash when initializing driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit 54a401af478 split out DriverConfigInit from DriverConfigNew, but
then called it a bit late from libxlStateInitialize. The cfg is used in
libxlDriverConfigLoadFile and when uninitialized results in a crash.
Calling DriverConfigInit immediately after DriverConfigNew fixes the
crash.
