xl create: endless loop

[Christoph Egger <Christoph.Egger@amd.com>]

Hi!

I cannot start a guest with 'xl create' due to an endless loop in libxl.c, 
function libxl__get_free_memory_slack():

There is this code snippet:

retry:
    free_mem_slack_s = libxl__xs_read(gc, XBT_NULL, free_mem_slack_path);
    if (!free_mem_slack_s) {
        rc = libxl__fill_dom0_memory_info(gc, &target_memkb);
        if (rc < 0)
            return rc;
        goto retry;
    } else {


libxl__xs_read() returns 0 and libxl__fill_dom0_memory_info() also returns 0.
So there's a loop of retries.

Christoph
