Description
Technical field
The present invention relates to cloud storage technical field of virtualization, especially a kind of physical machine and virtual machine mutually share cloud disk
Method.
Background technique
As education cloud application is more and more extensive, the scene as teacher shares personal information on church is seen everywhere, and
Traditional mode is exactly that the shared disk of Windows or the outer net address of file, shared cloud disk are supplied to student's access, is used
More new mode is exactly that cloud disk is shared between virtual machine and virtual machine, following problem:
It provides cloud disk shared function first is that being confined to cloud platform, can only realize that virtual machine and virtual machine share cloud disk,
It can not achieve and exchange shared cloud disk between physical machine and virtual machine, can not realize and share cloud disk between physical machine and physical machine.
Second is that the Network Abnormal of discovery virtual machine, user wants useful positioning tool to put on a virtual machine, but looks for
Less than good method.
It is tested third is that Test Engineer wants that the small tool that oneself or Developmental Engineer are developed is placed on virtual machine
When, it is necessary to it is shared by other network tools, when needing to share to more virtual machines, working efficiency and its low.
In order to improve the shared shared range areas of cloud disk, the data for effectively carrying out physical machine and virtual machine cloud disk mode are handed over
Mutually, the method for needing a kind of physical machine and the mutually shared cloud disk of virtual machine, is realized between multiple virtual machines and multiple physical machines altogether
Cloud disk is enjoyed, and Test Engineer's working efficiency for testing virtual machine is effectively provided.
Summary of the invention
Present invention solves the technical problem that being to provide the method for a kind of physical machine and the mutually shared cloud disk of virtual machine, solve
Physical machine and virtual machine mutually shared cloud disk the problem of, virtual machine Network Abnormal user position tool cannot be placed on virtual machine
Upper, Test Engineer tests the problems such as Virtual Machine Worker low efficiency.
The technical solution that the present invention solves above-mentioned technical problem is:
The method includes the following steps:
Step 1: cloud platform builds Storage Virtualization environment；
Step 2: creation cloud disk
Step 3: if thening follow the steps 3 to physical machine use, if thening follow the steps 9 to virtual machine use；
Step: 4: publication cloud disk；
Step 5: setting cloud disk access authority；
Step 6: PC (physical machine) logs in cloud disk；
Step 7: data are stored by PC；
Step 8: if shared cloud disk thens follow the steps 5 to other PCs (physical machine) use；If shared cloud disk gives it
He thens follow the steps 9 at virtual machine use；
Step 9: carry cloud disk is to virtual machine；
Step 10: data are stored by virtual machine；
Step 11: if shared cloud disk thens follow the steps 12 to other PCs (physical machine) use；If shared cloud disk is given
Other virtual machine uses then follow the steps 9；
Step 12: if cloud disk, which is not issued, thens follow the steps 4；If cloud disk, which has been issued, thens follow the steps 5.
The cloud platform build Storage Virtualization environment the following steps are included:
1) physical machine volume operation PV is carried out to local disk or logical unit number LUN block equipment
2) storage volume group VG is carried out to the PV again；It is exactly the new block device that so storage volume group VG, which manages memory space,.
The creation cloud disk is:
1) destination node is selected to carry out creation cloud disk；
2) logical volume LV is created based on storage volume group VG on the target node；
3) logical volume is made to be in unactivated state, all calculate nodes can check the presence of logical volume by volume group VG；
The publication cloud disk is that cloud disk is added by object machine Target as an independent logical unit number LUN；
The setting cloud disk access authority is the access control policy that object machine Target is arranged, as only allowed user
The access of PC IP address allows the PC IP network section of user to access.
It is that user passes through ISCSI client discovery object machine Target that the PC (physical machine), which logs in cloud disk,
Logical unit number LUN list, and be connected to logical unit number LUN belonging to cloud disk, the at this time PC (physical machine) of user
It can see new disk, if disk is unformatted, user can normal use after being formatted to it.
The carry cloud disk is as follows to virtual machine process:
1) logical volume is activated in the calculate node where virtual machine, makes its available mode, and other calculate nodes are kept
The unactivated state logical volume；
2) logical volume is mounted on virtual machine, and it is exactly cloud disk that virtual machine, which defaults it, and can be written and read.
The present invention provides physical machine and virtual machine mutually shared cloud disk, effectively solves virtual machine and object by ISCSI agreement
The problem of reason machine application data interaction, avoids the Network Abnormal user of virtual machine from position tool cannot being put asking on a virtual machine
Topic, while also improving the working efficiency that Test Engineer tests virtual machine.The present invention, which solves cloud platform, can not achieve physical machine
PC, which is carried, with the mutually shared cloud disk of virtual machine, user thinks that shared data is not convenient enough, virtual to the virtual machine of cloud platform
Operation maintenance personnel cannot upload the problems such as tool of positioning Network Abnormal problem when machine Network Abnormal；It can be applied to cloud platform and user
In the information sharing of PC.
