You can change it by specifying /domain/memtune/hard_limit in domain
XML; see http://libvirt.org/formatdomain.html#elementsMemoryTuning

Libvirt will use the hard_limit value for RLIMIT_MEMLOCK, but only if
needed. So it will be set only if any of the following is true:
    - you are on PPC64
    - the /domain/memoryBacking/locked is set
    - a VFIO device passthrough is used
    - an RDMA migration is initiated.
