[libvirt] [PATCH v3 00/13] Implement memory control api

Changelog from v2: * Implement virDomainGetMemoryParameters api * Add virDomainGetMemoryParameters to memtune command in virsh * Provide domainGetMemoryParameters implementation for remote, QEmu and LXC drivers * Auto-generate code using rpcgen and remote_generate_stubs.pl * Squash all the changes related to remote driver and remote protocol into one single patch. * Patch re-ordering Changelog from v1: * Patch re-ordering for compilation * Folded python bindings changes to patch 01 * Added defines for string constants for memory tunables * Typo fix: min_guarantee * Moved initialization of function pointers in driver.h patch This patch series implement public api for controlling various memory tunables exported by the OS. This is based on the following RFC[1]. * Implement virDomainSetMemoryParameters api * Provide implementation for remote, QEmu and LXC drivers * Enable memory controller support fro QEmu * virsh command for runtime changes to the memory parameters * Domain configuration parsing for memory control parameters * Cgroup memory controller code for memory hard_limit/soft_limit, swap hard_limit To Do * Python bindings is just a place holder, need to implement 1. https://www.redhat.com/archives/libvir-list/2010-August/msg00607.html 2. https://www.redhat.com/archives/libvir-list/2010-August/msg00699.html --- Nikunj A.
