Problems solved by technology
[0013] When there are a large number of virtual machines running in a server cluster at the same time, limited by the disk I / O capacity of the shared storage or the network bandwidth connected to the shared storage, when many virtual machines access the shared storage at the same time, each virtual machine will experience a memory failure. I / O performance degrades, causing storage to become the bottleneck of the entire system
[0014] In addition, for a virtual machine stored on a shared storage device, no matter whether it is running storage-intensive applications or not, the GuestOS on the virtual machine needs to frequently access the shared storage for read and write operations, which also leads to the I / O of the virtual machine. reduced performance

Embodiment Construction
[0047] According to the technical solution provided by the present invention, according to the high-availability attribute label of the virtual machine, when the virtual machine does not have the high-availability attribute, the image file of the virtual machine is stored in the local storage space of the physical server, or according to the storage space on the shared storage space. The cache scheduling attribute label of the virtual machine in the image file schedules the operating system cache of the virtual machine to the local storage space of the physical server where the virtual machine is currently running, thus making full use of the local storage space of the physical server and avoiding all virtual machines. The I / O performance degradation problem caused by both the computer and its operating system cache being stored in the shared storage space.
[0048] In addition, since the technical solution provided by the present invention stores the image file of the virtual ...

The invention discloses a method, a system and a device for virtual machine arrangement. The method comprises the steps: a yes-no high availability attribute tag of a virtual machine is identified; according to the yes-no high availability attribute tag, yes-no the virtual machine has a high availability attribute or not is judge; if the answer is positive, a mapping file of the virtual machine is stored in a storage sharing space; and if the answer is negative, the mapping file of the virtual machine is stored in a local storage space of a physical server. The yes-no high availability attribute tag is used for identifying whether the virtual machine has the high availability attribute tag or not. The method is capable of improving input / output (I / O) performance of the virtual machine.
Description
technical field [0001] The present invention relates to the technical field of virtual machines, in particular to a virtual machine deployment method, system and device. Background technique [0002] Server virtualization is an abstraction of server computing resources. On the basis of a physical server, resources are divided into multiple independent "virtual" software operating environments, that is, divided into multiple independent virtual machines. In this way, server physical resources such as CPU, memory, and I / O are transformed into a set of logical resources that can be managed flexibly and allocated dynamically. Run their respective operating systems and applications. [0003] Virtualization technology is conducive to improving the resource utilization of servers, solving the problem of unbalanced utilization of resources in different application systems, meeting the dynamic changing needs of business applications for resources, and reducing the TCO (Total Cost of...
