Re: [libvirt] [PATCH v3] qemu: Forbid <memoryBacking><locked> without <memtune><hard_limit>

In order for memory locking to work, the hard limit on memory locking (and usage) has to be set appropriately by the user. The documentation mentions the requirement already: with this patch, it's going to be enforced by runtime checks as well, by forbidding a non-compliant guest from being defined as well as edited and started. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1316774 --- Changes from [v2] * Address review feedback: - move the check from BuildCommandLine to Validate. Changes from [v1] * Address review feeback: - check in BuildCommandLine rather than in PostParse, so that non-compliant guests will merely fail to start rather than disappear completely.
