[Qemu-devel] [trivial one-liner] be more specific in -mem-path error messages

[Michael Tokarev]

The error message qemu gives when hugetlbfs is not
accessible is cryptic at best:

  mkstemp: Permission denied

Make it a bit more specific instead:

 unable to create backing store for hugepages: Permission denied

Thanks!
