[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH V4 01/24] xl / libxl: push parsing of SSID and CPU pool ID down to libxl
This patch pushes parsing of "init_seclabel", "seclabel",
"device_model_stubdomain_seclabel" and "pool" down to libxl level.
Originally the parsing is done in xl level, which is not ideal because
libxl won't have the truely relavent information. Now libxl holds
important information by itself. This is useful when we do serialization
and deserialization of domain configurations on libxl level.
The libxl IDL is extended to hold the string of labels and pool name.
And if there those strings are present they take precedence over the
numeric representations.
As all relavent structures have a field called X_name / X_label now, a
string is also copied there so that we can use it directly.
In order to be compatible with users of older versions of libxl, this
patch also defines LIBXL_HAVE_SSID_AND_CPUPOOLID_PARSING. If it is
defined, those strings are available. And if those strings are not NULL,
libxl will do the parsing and ignore the numeric values.
