The KVM Agent had two mechanisms for reporting its capabilities and memory to the Management Server. On startup it would ask libvirt the amount of Memory the Host has and subtract and add the reserved and overcommit memory. When the HostStats were however reported to the Management Server these two configured values on the Agent were no longer reported in the statistics thus showing all the available memory in the Agent/Host to the Management Server. This commit unifies this by using the same logic on Agent Startup and during statistics reporting. memory=3069636608, reservedMemory=1073741824 This was reported by a 4GB Hypervisor with this setting: host.reserved.mem.mb=1024 The GUI (thus API) would then show: Memory Total 2.86 GB This way the Agent properly 'lies' to the Management Server about its capabilities in terms of Memory. This is very helpful if you want to overprovision or undercommit machines for various reasons. Overcommitting can be done when KSM or ZSwap or a fast SWAP device is installed in the machine. Underprovisioning is done when the Host might run other tasks then a KVM hypervisor, for example when it runs in a hyperconverged setup with Ceph. In addition internally many values have been changed from a Double to a Long and also store the amount of bytes instead of Kilobytes. Signed-off-by: Wido den Hollander <wido@widodh.nl> |

Apache CloudStack 
Apache CloudStack is open source software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform. CloudStack is used by a number of service providers to offer public cloud services, and by many companies to provide an on-premises (private) cloud offering, or as part of a hybrid cloud solution.
CloudStack is a turnkey solution that includes the entire "stack" of features most organizations want with an IaaS cloud: compute orchestration, Network-as-a-Service, user and account management, a full and open native API, resource accounting, and a first-class User Interface (UI).
CloudStack currently supports the most popular hypervisors: VMware vSphere, KVM, XenServer, XenProject and Hyper-V as well as OVM and LXC containers.
Users can manage their cloud with an easy to use Web interface, command line tools, and/or a full-featured query based API.

Notice of Cryptographic Software
This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See http://www.wassenaar.org/ for more information.
The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code.
The following provides more details on the included cryptographic software:
- CloudStack makes use of JaSypt cryptographic libraries.
- CloudStack has a system requirement of MySQL, and uses native database encryption functionality.
- CloudStack makes use of the Bouncy Castle general-purpose encryption library.
- CloudStack can optionally interacts with and controls OpenSwan-based VPNs.
- CloudStack has a dependency on and makes use of JSch - a java SSH2 implementation.
