[PATCH] lxc: report error message raised by the failing function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The code that calls VIR_WARN after a function fails, doesn't
report the error message raised by the failing function.
Such error messages are now reported in lxc/lxc_driver.c
