my xen version is 4.2.1

not matter how I modify the function : libxl_set_memory_target 

in libxl.c, ie: add return 0, or assert ...

the xl command behaves the same.

an example is:

run a guest domain, and use command: xl mem-set GUESTID 33333333

then it will output an error as: libxl: error: libxl.c:3455:libxl_set_memory_target: memory_dynamic_max must be less than or equal to memory_static_max

this error message is in tools/libxl/libxl.c, near LINE 3428, in the if (new_target_memkb > memorykb){LIBXL__LOG.}

change the message to any characters, recompile and install xen, reboot

xl mem-set GUESTID 33333333, the original message come out again!

I have been trapped in this for ten hours. Has anyone ever modified the libxl.c successfully?

libxl.c forms part of libxenlight.so.$VERSION, so unless you are reinstalling your librarys rather than just reinstalling `xl`, you really wont see any difference.
