This section focuses on the scheduling mechanism and implementation of Nova-scheduler, which solves the problem of choosing which compute node to start instance on.When you create a Instance, users ask for resource requirements, such as CPU, memory, and how much disk each needs.OpenStack defines these requirements in flavor, and the user only needs to specify which flavor to use.The available flavor are managed in system->flavors.Flavor mainly defines

There are many comments on installing and configuring openstack Nova on Ubuntu. At least six netizens may encounter Ping failure. To be honest, there are many reasons for ping failure (the most common one isEuca-authorize authorization problem). If no useful information is provided, it is difficult to judge the problem by leaving a "Ping failure". We suggest you try to clarify your situation when leaving a message in the future, provide as much inform

The code for the Nova part of OpenStack has been studying for a while. Especially want to know, how to debug the code with Eclipse, also in the Forum asked others, no results, no one reply to me. Finally, I found out the way out.Let's write down the path of your exploration. I am an OpenStack environment built with Devstack. The build step can be found in one of my other blog posts.My Nova code does not hav

(this version is tested using NFS) Instances: Instance must keep running without any EBS volume. Pre-requisite settings (A) sharedStorage As mentioned above, shared storage is inevitable forLive_migration functionality. An example is NFS (my test environment ),And example setting is described below. Prepare NFS s

Open Stack Compute Infrastructure (Nova) Nova is the computational organization controller in the OpenStack cloud. All activities that support an instance (instances) lifecycle in the OpenStack cloud are handled by the Nova. This makes Nova a platform for managing computing resources, networks, certifications, and sca

Nova Physical Deployment ScenarioWe've seen that Nova is made up of a lot of sub-services, and we know that OpenStack is a distributed system that can be deployed to several nodes, and then you might ask: How do Nova's services physically be deployed?For Nova, these services are deployed on two types of nodes: compute nodes and control nodes. The Hypervisor is in

A problem was found after the VMware Mech driver implementation was completed last week. The test found that the network created by neutron, the virtual machine created with Nova, was created on different ESXi hosts, and of course there was no such problem with only one ESXi host in cluster. Switch to Nova-network, and found that there is also this problem. The bug was reported on the launchpad: With the ne

IntroductionOPS colleagues often encounter these four questions: How does Nova count OpenStack computing resources? Why FREE_RAM_MB, FREE_DISK_GB will be negative? Even if FREE_RAM_MB, FREE_DISK_GB is negative, why is the virtual machine still able to create success? The use of random scheduling due to insufficient resources will cause the virtual machine to fail, while the specified host can be created successfully? This art
