From e40b659d320b3c6894862b87adf1011e31cbf8fc Mon Sep 17 00:00:00 2001 From: Chuck Short Date: Tue, 31 Jan 2012 20:53:24 -0500 Subject: Add support for LXC volumes. This introduces volume support for LXC containers in Nova. The way that this works is that when a device is attached to an LXC container is that, the xml is parsed to find out which device to connect to the LXC container, binds the device to the LXC container, and allow the device through cgroups. This bug fixes LP: #924601.
