.　　Openstack≠ virtualization SoftwareFirst, it is not a virtualization software (this must be known),although OpenStack manages virtual machines, but does not have the functionality of virtualization , it provides a virtualized environment for the upper layer, must rely on a third-party virtualization software, such as the default supported Linux The kernel virtual machine, which is automatically brought af

KVM Virtual machine Dynamic migration requires no copying of virtual disk files, but requires the same directory structure virtual machine disk files between the virtual hosts that need to be migrated, compared to the need to copy virtual machine virtual disk files in the static migration of a KVM virtual machine. This part of this article is implemented by NFS, and of course it can be implemented by the

Multi-thread compression and Migration Technology in QEMU-KVM, qemu-kvm MultithreadingMulti-thread compression and Migration Technology in QEMU-KVM Guide Currently, the Migration technology is to directly write raw memory data to QEMUFILE to transfer virtual machines. In this case, a large amount of data is sent, this results in a higher migration t

The entire life cycle of instance from creation to deletion is managed by Nova. In the following sections, we take the different operational scenarios in the instance life cycle as an example to analyze in detail how the different Nova components work together and deepen your understanding of Nova through log analysis.Before we study Nova's operations, let's start by learning one important thing: the OpenStack logs.OpenStack's log records very detaile
