When building OpenStack, many people will refer to the example and steps on "OS-compute-startguide-trunk" and select Ubuntuserver12.04 for installation. The above steps must be correct, but because the documents cannot be all-encompassing and the system settings will not be identical, errors are inevitable during the installation process.

Nova provides the novncproxy proxy to allow users to access virtual machines through VNC. Users can access virtual machines through websocket, Java client, or spicehtml5. The function of accessing a virtual machine through websket has been integrated into horizon, and the corresponding software needs to be installed first through the Java client. To facilitate user access to virtual machines, Nova uses a pr

In general, OpenStack requires at least two physical machines, or two nodes, the control nodes and compute nodes mentioned earlier. In general, the control node does not require excessive hardware resources, compute nodes need a relatively high hardware resources, but often the user's two nodes of the hardware information is the same, so we will also install Nova on the control node, to use the Control node hardware resource information. Second, inst

Nova is a compute service that can start a virtual machine instance. These services can be configured on a separate node or on the same node. Most services run on the controller node and run the virtual machine service on a dedicated compute node. This time, we deploy the compute to the control node.4.1 Install Compute Controller services (Installation Compute service)4.1.1 installation of compute required Packages# yum Install Openstack-

NOVA (openstack component) Openstack consists of two main modules: Nova and swift. The former is the virtual server deployment and business computing module developed by NASA, and the latter is the distributed cloud storage module developed by rackspace, which can be used together, it can also be used separately. Nova is the core, with a set of virtualization man

Conceptual digoal Logical digoal Nova is the most complicated and distributed component of openstack. A large number of processes cooperate to turn end user API requests into running virtual machines. Below is a list of these processes and their functions: Nova-API accepts and responds to end user compute api cils. it supports openstack compute API, Amazon's EC2 API and a Special admin API (for privileg
