7:14 a.m.
Changelog from v3:
* Add unsigned int flags to the public api and make corresponding changes
further down till the drivers(qemu, lxc and remote)
* Move exporting of the api's to patch two
* Added memtune test in tests/qemuxml2xmltest.c
* Fix: src/conf/domain_conf.c - print memtune element only if tunable
is present
* Fix: src/qemu/qemu_driver.c - call cgroup apis only if nonzero
* Fix: src/lxc/lxc_controller.c - call cgroup apis only if nonzero
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
