This article describes 4th generation resource management, how to be used in Virtuozzo 7.test [[VSwap]] functionality
{{Virtuozzo}} == Introduction == Each container is assigned RAM and SWAP limits. When a container hitsthe RAM limit a (slow) swapout starts. When it hits the SWAP limit anOOM killer is invoked for that container. Note, that when a container hits its RAM limit, but there is enough RAMon the host pages do not go to *real* swap, but instead are cached inhost RAM. Real swapout starts when there is no more real RAM. The sameis fair for FS page cache - clean cache pages are moved to the host RAMinstead of being dropped when a container hits its RAM limit so that nopagein will happen on the next read provided there is enough free RAM onthe host. The base functionality will be available in * vzkernel-3.10.0-123.1.2.vz7.5.17* vcmmd-7.0.6 == How to test == [originally written by xemul@ for vswap]
We need the following set of atomic tests
6) No leaks happen after container stop. This will be done using kmemleak - see PSBM-34183
More details will come later.
