Abstract
The present invention relates to the technical field of cloud computing, and particularly relates to a method for externally resetting a password of a windows virtual machine. The method comprises: firstly, entering a background directory of a host machine where the Windows virtual machine is positioned; then mounting files of a C disk of the virtual machine to a mnt directory; next, entering a mounting directory, replacing a sam file in a WINDOWS/repair file with a WINDOWS/system32/config/SAM file; and finally, rebooting the virtual machine, and completing resetting the password of the virtual machine. According to the method, a third party tool does not need to be installed and the method is simple and fast; the method has universality and can be used for a Windows operating system; personal data of users in an original operating system cannot be damaged; and the method can be used for resetting the password of the windows virtual machine.
Description
Technical field
The present invention relates to field of cloud computer technology, refer to that a kind of outside resets the method for windows virtual machine password especially.
Background technology
Under cloud computing environment, virtual machine is widely used, and the maintenance requirement for virtual machine is more and more higher, owing to forgetting Password for client, needing to reset Windows virtual machine password is the difficult problem that O&M often runs into, and generally runs into this situation, has following solution:
1, third party's instrument is adopted to crack virtual machine password, as carry WinPE.
2, refitting VME operating system.
There is following drawback in said method:
1, adopt third party's instrument to crack virtual machine password, operate cumbersome, the time is relatively more of a specified duration, there is not versatility;
2, VME operating system of resetting can cause user data loss, inadvisable.
Summary of the invention
The technical matters that the present invention solves is to provide a kind of outside to reset the method for windows virtual machine password, solve the deficiency that classic method exists, without the need to installing third party's instrument, simple and fast, there is versatility, can use for Windows operating system, not damage original operating system users personal data, for cloud platform O&M provides a kind of practicable solution.
The present invention solves the problem, and comprises the following steps:
Described method comprises the steps:
Step 1: enter Windows virtual machine place host catalogue;
Step 2: by virtual machine C dish file mount to mnt catalogue;
Step 3: enter mount directory, replaces WINDOWS/system32/config/SAM file by sam file under WINDOWS/repair/ file;
Step 4: restart virtual machine, completes virtual machine password and resets.
Described host, refers to the physical node creating virtual machine place.
Described sam file, be the account database of windows, the relevant informations such as the login name of all users and password are all preserved in this document.
Described mnt is the abbreviation of mount, the catalogue of mounting CD-ROM drive, USB device, block device, after loading, can have more the catalogue of relevant device in mnt.
Described replacement, refers to and Windows virtual machine password is become empty.
Method of the present invention is without the need to installing third party's instrument, simple and fast; There is versatility, can use for Windows operating system; Do not damage original operating system users personal data.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described:
Fig. 1 is process flow diagram of the present invention.
Embodiment
Embodiments of the present invention have multiple, and will be that example illustrates wherein a kind of implementation method based on KVM virtualization implementation here, as shown in Figure 1, specific implementation process be as follows for process flow diagram
1, Windows virtual machine place host catalogue is entered
#cd/instances/work/admin/i-A1D93C99/
2, by virtual machine C dish file mount to mnt catalogue
#/opt/qemu1.2/bin/qemu-nbd-c/dev/nbd0emi-507A3AF8_snap.qcow2
#ntfs-3g/dev/nbd0p1/mnt/i-A1D93C99/ // attention, if windows2008 and win7 operating system, nbd0p1 will make nbd0p2 into
#cd/mnt/i-A1D93C99/|ll
3, enter mount directory, sam file under WINDOWS/repair/ file is replaced WINDOWS/system32/config/SAM file
#cpWINDOWS/repair/samcp/mnt/WINDOWS/system32/config/SAM//attention copy past is capitalization
4, restart virtual machine, complete virtual machine password and reset
#virshcreatelibvirt.xml。
