Turns out this check is excessively strict: there are ways other than <memtune><hard_limit> to raise the memory locking limit for QEMU processes, one prominent example being tweaking /etc/security/limits.conf. Actually, it seems that limits.conf doesn't work with libvirt as mentioned by Daniel in another thread. I didn't know this myself btw. This makes this series even more important because only through libvirt we can set this limit to infinity.
Well, it *does* work if you set it up properly, eg. raise the memory locking limit for the user under which libvirtd will run instead of the user under which QEMU processes will run. Doing so is very counter-intuitive, though. -- Andrea Bolognani / Red Hat / Virtualization
