Description
Technical field
The present invention relates to virtual desktop infrastructure technologies fields, and in particular to a kind of virtual machine broadcasting client computer of VDI
Music CD method and system.
Background technology
VDI, full name in English Virtual Desktop Infrastructure, i.e. virtual desktop architecture.It is not
The desktop PC of an operation Windows 7 or Windows 10 is configured to each user, but passes through the clothes in data center
Be engaged in device operation Windows 7 or Windows 10, and desktop is virtualized；User is by coming from client device (client computer
Or home PC) client calculate agreement and be attached with virtual desktop, user access their desktop be like access it is traditional
Locally-installed desktop it is the same.
Music CD (audio CD), also known as CD-DA (Compact Disc-Digital Audio).Audio number on CD
According to being stored on one or more tracks (tracks).Each track is typically a song.At most may be used on one standard CD-DA
To there is 99 tracks.One track may include several sectors.Each sector includes the data of 2352 bytes, and has additional byte
For error detection and correction and control structure.
In the scene of greenfield deployment, user generally uses thin-client, when if necessary to use client CD-ROM drive, generally
Using USB CD-ROM drives, then USB CD-ROM drives are redirected by USB redirecting techniques and are used to virtual machine.But actual user's
In usage scenario, often exists and need the existing old PC of user being linked into VDI systems, these old PC have often carried SCSI
(Small Computer System Interface, small computer system interface) CD-ROM equipment, so in order to improve user
To the degree of recognition and overall solution cost of product, it is necessary to which solution allows virtual function asking using client computer SCSI CD-ROM equipments
Topic.
A kind of thinking for solving the problems, such as this at present is：Client computer CD-ROM drive is passed through into iscsi (Internet Small
Computer System Interface, Internet Small Computer Systems Interface) it is shared away as block device, then exist
Server end logs in iscsi, by the block device that client computer iscsi carries are server, then passes through libvirt
(libvirt is the API to increase income for managing virtual platform, is a kind of background program and management tool, it can be used for pipe
Manage KVM, Xen, VMware ESX, QEMU and other virtualization technologies.) update-device interfaces in interface are by virtual machine
In CD replace with the block device that carry is logged in above by iscsi, to achieve the purpose that the CD-ROM drive using client computer.But
Due to the particularity of music CD itself, it is the same that the Linux system of server-side without the image of Buddha reads common optical data disk, uses standard
Read interfaces read music CD, institute's method described above can not solve virtual machine normal use distal end SCSI CD-ROM drives and play music
CD。
Music CD as also largely existing at present, and will a kind of long-standing CD therefore how to allow virtual function
It is the problem that desktop virtualization product must solve that the SCSI CD-ROM drives of normal use client computer, which carry out music CD broadcastings,.
Invention content
In view of the deficiencies in the prior art, the purpose of the present invention is to provide the virtual machines of VDI a kind of to play client
The method and system of the music CD of machine make the SCSI CD-ROM drives of virtual function normal use client computer carry out music CD broadcastings, user
Use simple, transparent, performance higher.
To achieve the above objectives, the technical solution adopted by the present invention is that：A kind of virtual machine of VDI plays the music of client computer
The method of CD, the VDI include server and client computer, and the virtual machine operates on the server：
