X-Git-Tag: CVE-2013-2230~52
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=59cc0fe5aa00d472bdd19bfb40be219249cfd0c7;p=thirdparty%2Flibvirt.git

qemu: Set RLIMIT_MEMLOCK when memoryBacking/locked is used

If a domain is configured to have all its memory locked, we need to set
RLIMIT_MEMLOCK so that QEMU is actually allowed to lock the memory.
