qemuSetupMemoryCgroup: Handle hard_limit properly
Since 16bcb3 we have a regression. The hard_limit is set unconditionally. By default the limit is zero. Hence, if user hasn't configured any, we set the zero in cgroup subsystem making the kernel kill the corresponding qemu process immediately. The proper fix is to set hard_limit iff user has configured any.
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
