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.
