[libvirt] [PATCH 0/6] Fixes for memory locking limit

The code dealing with RLIMIT_MEMLOCK contained a few assumptions that hold for x86 but don't necessarily work as well for other platforms, eg. that qemu will need to lock memory only when VFIO passthrough is involved. This series removes such assumptions by removing ad-hoc code and making sure that the function containing the correct logic is called instead; it also implements the platform-specific calculations needed to calculate the correct RLIMIT_MEMLOCK value for ppc64 guests. Patches 1-4 are architecture-agnostic, patches 5-6 are specific to ppc64. Cheers. Andrea Bolognani (6): process: Log when limiting the amount of locked memory qemu: Use qemuDomainRequiresMlock() in qemuBuildCommandLine() qemu: Use qemuDomainRequiresMlock() when attaching PCI hostdev qemu: Reduce memlock limit after detaching hostdev qemu: Always set locked memory limit for ppc64 domains qemu: Add ppc64-specific math to qemuDomainGetMlockLimitBytes() src/qemu/qemu_command.c | 9 ++--- src/qemu/qemu_domain.c | 89 +++++++++++++++++++++++++++++++++++++++++++++++-- src/qemu/qemu_hotplug.c | 29 ++++++++++++---- src/util/virprocess.c | 4 +++ 4 files changed, 116 insertions(+), 15 deletions(-) -- 2.5.0
