Detailed Description
In the prior art, if a user wants to copy files in a USB flash disk to a virtual machine, the user needs to plug the USB flash disk into a USB interface of a host where the virtual machine is located, and then mounts the USB flash disk to the virtual machine, so that the files in the USB flash disk can be read and written in the virtual machine. However, when the openstack cluster is large, the number of hosts and virtual machines increases, the virtual machines are distributed on different hosts, and this time, it is very troublesome to mount USB devices by using the conventional USB through scheme, because the hosts where the USB devices are located need to be changed back and forth or a large number of USB devices are prepared, and the virtual machines on which the USB devices are mounted cannot be migrated, which is complicated to use and has low efficiency. In order to overcome the technical problems, the application provides a management method of USB devices in a cluster, which can solve the problem that the USB devices can only be mounted on a virtual machine on a host machine, and simultaneously avoid the limitation that the virtual machine cannot migrate after the USB devices are mounted.
The embodiment of the application discloses a method for managing USB equipment in a cluster, which is applied to a host in the cluster, and can comprise the following steps as shown in FIG. 1:
Step S11, obtaining equipment information of local available USB equipment, and distributing a port number for each available USB equipment.
In this embodiment, first, device information of locally available USB devices, that is, available USB devices connected to a current physical host, is acquired, and a network port number is allocated to each available USB device.
In this embodiment, the obtaining the device information of the locally available USB device may include querying a local USB device list, and filtering virtual USB devices from the USB device list according to a target parameter field corresponding to each USB device to obtain the device information of the available USB device. That is, the computing service of each host in the cluster actively queries the USB list on the host at the time of starting, and filters out some unavailable virtual USB devices carried by the operating system, so as to obtain the device information of the available USB devices.
And step S12, acquiring a host IP, and obtaining a unique number corresponding to each available USB device based on the host IP and the port number.
In this embodiment, by obtaining the host IP and obtaining the unique number corresponding to each available USB device based on the host IP and the port number, therefore, one USB device is uniquely identified by the host IP and the network port number, and no longer is the conventional vendor ID and productor ID, which can effectively avoid the disadvantage that the cloud platform can only identify one USB device when different USB devices have the same vendor ID (manufacturer identification) or product ID (product identification).
And S13, sharing the unique numbers corresponding to all the available USB devices to a cluster database through a network protocol, so that any host in the cluster can mount the USB device to be mounted to the target virtual machine according to the unique number of the USB device to be mounted and the ID of the target virtual machine.
In this embodiment, for example, as shown in fig. 2, after determining the unique numbers of the available USB devices, the sharing service is started to share the unique numbers of the USB devices through the network protocol. In this embodiment, sharing the unique numbers corresponding to all the available USB devices to the cluster database through the network protocol may include uploading the unique numbers corresponding to all the available USB devices and associated parameter information to the cluster database through a transmission control protocol, where the parameter information includes a host name, a device manufacturer identifier, and a device product identifier. The unique number corresponding to the USB device and the associated parameter information are shared to the cluster database through a transmission control protocol (TCP, transmission Control Protocol) protocol, wherein the parameter information includes, but is not limited to, a host name of a host where the USB device is located, a manufacturer identifier (product ID) of the USB device, and a product identifier (vendor ID) of the USB device, and the data shared to the cluster database may include, but is not limited to, the unique number composed of the host IP and the port number, and the host name, the product ID, and the vendor ID. Each host in the cluster can share the available USB equipment of the host in the mode, so that when any host in the cluster needs data in a certain USB equipment, the USB equipment to be mounted is mounted to the target virtual machine according to the required unique number of the USB equipment to be mounted and the ID of the target virtual machine. Specifically, when the user wants to mount the USB device to be mounted on the virtual machine, the user may select the USB device and the target virtual machine to be mounted from the USB list of the virtual machine device management interface. Therefore, the problem that the USB equipment can only be mounted on the virtual machine on the host computer in the traditional USB through scheme is solved, and meanwhile, the limitation that the virtual machine cannot be migrated after the USB equipment is mounted is avoided. The embodiment is suitable for an OpenStack large-scale cluster scene, wherein OpenStack is an open-source cloud computing management platform project and is a combination of a series of software open-source projects.
In this embodiment, the target virtual machine is a virtual machine created based on Libvirt, and the host mounts the USB device to be mounted to the target virtual machine according to the unique number of the USB device to be mounted and the ID of the target virtual machine, which may include receiving a mounting request, where the mounting request includes the unique number of the USB device to be mounted and the ID of the target virtual machine, generating redirection configuration information based on the unique number of the USB device to be mounted and the ID of the target virtual machine, and mounting the USB device to be mounted to the target virtual machine by using Libvirt service based on the redirection configuration information. Specifically, the computing service of the host may splice redirdev xml files of the device, that is, configuration files, according to the virtual machine ID selected by the user and the host IP and port number corresponding to the USB device, and send the request to libvirt, libvirt, and mount the USB device to be mounted to the target virtual machine after receiving the request.
In this embodiment, after sharing unique numbers corresponding to all the available USB devices to a cluster database through a network protocol, uploading associated information corresponding to all the available USB devices and including the unique numbers to a cloud management platform, and adding corresponding parameter information to each USB device through the cloud management platform, where the parameter information includes a device use state and a device use permission.
It can be appreciated that all USB devices in the cluster can be managed by the cloud management platform, and bong can improve the security of device sharing by setting the use authority for the USB devices, such as setting that the USB devices can be used by those virtual machines. Specifically, the database can be queried through Api (Application Programming Interface, application program interface) service of the host to obtain all available USB device lists and USB related information in the cluster, including unique numbers composed of host IP and port numbers, host names, product IDs, vendor IDs, etc., and the unique numbers are uploaded to the cloud platform management interface, and the interface uniformly displays the available USB device lists in the cluster, and manages the device use states and device use rights. For example, as shown in fig. 3, an administrator logs in a virtual machine management platform, selects a cloud host from a cloud management platform list, selects a USB device to be mounted from a cloud host operation list, selects a corresponding host, selects a USB device to be mounted from a host USB list, and sets permission to implement sharing control, so that the USB device to be mounted is in a usable state.
In this embodiment, after the USB device to be mounted is mounted to the target virtual machine, updating, by the cloud management platform, a device usage state of the USB device to be mounted, and adding corresponding mounting information, where the mounting information includes attribute information of the target virtual machine. The state of the USB device to be mounted is set to be a use state, and relevant mounting information is added to the USB device to be mounted, wherein the mounting information comprises, but is not limited to, attribute information of a target virtual machine corresponding to the USB device to be mounted, such as a virtual machine ID, a memory and the like, so that information of the virtual machine associated with the USB device can be displayed.
In this embodiment, after adding the corresponding parameter information to each USB device through the cloud management platform, the method may further include monitoring the device usage status in real time, and automatically updating the device usage rights according to the type of the device usage status. When the use state of the equipment is monitored to be the use state, the equipment use permission of the corresponding equipment is automatically updated to be unusable, so that the abnormality caused by excessive equipment connection is avoided.
Therefore, in this embodiment, by allocating a port number to each USB device, and then using the host IP and the port number as the unique numbers to identify one USB device, further sharing the USB device on any host in the cluster according to the unique numbers through the network protocol, so that the virtual machine on any host in the cluster can connect the required USB device through the host IP and the port number, thereby implementing redirection of the USB device, uniformly managing all USB devices in the cluster, and avoiding the limitation that the virtual machine cannot migrate after mounting the USB device.
Correspondingly, the embodiment of the application also discloses a device for managing the USB equipment in the cluster, which is shown in fig. 4, and comprises the following steps:
the device information acquisition module 11 is configured to acquire device information of locally available USB devices, and allocate a port number to each of the available USB devices;

And the sharing module 13 is configured to share the unique numbers corresponding to all the available USB devices to a cluster database through a network protocol, so that any host in the cluster mounts the USB device to be mounted to the target virtual machine according to the unique number of the USB device to be mounted and the ID of the target virtual machine.
From the above, in this embodiment, by acquiring device information of local available USB devices and allocating a port number to each of the available USB devices, acquiring a host IP, obtaining a unique number corresponding to each of the available USB devices based on the host IP and the port number, sharing the unique numbers corresponding to all the available USB devices to a cluster database through a network protocol, so that any host in the cluster mounts the USB device to be mounted to the target virtual machine according to the unique number of the USB device to be mounted and the ID of the target virtual machine. Therefore, by allocating port numbers to each USB device and then using the host IP and the port numbers as unique numbers to identify one USB device, USB devices on any host in the cluster can be further shared out through a network protocol according to the unique numbers, virtual machines on any host in the cluster can be connected with required USB devices through the host IP and the port numbers, redirection of the USB devices is realized, the problem that the USB devices can only be mounted on the virtual machine on the host in the traditional USB direct scheme is solved, and meanwhile, the limitation that the virtual machines cannot migrate after the USB devices are mounted is avoided.
