It's hard for our friends to deploy the openstack environment. By default, there will be an image of the Ubuntu system. What if you want to use centos or other systems? The next step is to create a system. If you create any system that is supported by openstack, you don't have to worry about the lack of system resources;
If you have problems installing and configuring virt-manager, see my previous article;
Background and overviewSwift was originally a highly available distributed object Storage service developed by Rackspace, and in 2010 contributed to the OpenStack open source community as one of its initial core sub-projects, providing virtual machine image storage services for its Nova subproject. Swift is built on a less expensive standard hardware

It is clear that traditional commercial storage needs to adapt to this trend of computing development and respond.
Open-stack is favored by major storage vendors, OpenStack Cinder can easily access commercial storage, that is to say, the st
block storage device provided by Target supports a variety of implementations, and the LV is used in our experimental environment. The Cinder storage node Cinder-volume uses the TGT software by default to manage and monitor ISCSI target, nova-compute using ISCSIADM to perform initiator-related operations on compute nodes.Let's take a look at the flowchart of Attach operation

For beginners, OpenStack manual deployment is cumbersome and takes more time to learn. But we can use deployment scripts to install OpenStack.
Online there is a known as the most stupid OpenStack deployment tool called Devstack. I used to think it was quite a fool. The component is pu

IBM and RedHat may soon join the OpenStack support camp, which will largely promote the development of this cloud open source code project. GigaOm first reported the news that IBM and RedHat will join the OpenStack team, but the news has not yet been confirmed by both companies and OpenStack. OpenStack is a cloud compu

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?
