Embodiment
The virtual machine monitor of the embodiment of the invention, in dummy machine system and the client operation system state acquiring method, in the process of creating GOS, VMM is recorded as the virtual memory that GOS distributes, and the corresponding relation between virtual memory and the actual physics internal memory, when needs obtain the state of GOS, according to the corresponding relation between virtual memory and the actual physics internal memory, obtain the related data that writes down in the physical memory, be saved in the DUMP file.
The embodiments of the invention dummy machine system comprises physical hardware, VMM and GOS, wherein:
As shown in Figure 1, described VMM comprises:
Distribution module is used to client operating system to distribute virtual memory;
Mapping block is used to set up the mapping relations between described virtual memory and the actual physics internal memory;
Preserve module, be used for corresponding sign and described mapping relations of preserving described client operating system;
First acquisition module is used for after the state of receiving obtains instruction, according to the sign of the client operating system in the described instruction, determines to identify the first corresponding mapping relations with described client operating system in the described preservation module;
Second acquisition module is used for obtaining the first actual physics internal memory that described first mapping relations write down;
The first data message read through model is used for reading first data message of the described first actual physics internal memory;
The first data message writing module is used for first data message of the described first actual physics internal memory is write true I/O equipment.
Certainly, this data message writing module is unnecessary in some cases, only utilizes first data message to carry out subsequent analysis at needs and uses just needs.
Certainly, more simply be, preserve the directly corresponding sign of described client operating system and the actual physics internal memory of the actual use of this client operating system (just preserving the corresponding relation between the actual physics internal memory of client operating system and its actual use) preserved of module, first acquisition module and second acquisition module unite two into one, and the first actual physics internal memory that directly obtains client operating system gets final product.
Comprehensive two kinds of above-mentioned implementations can be found, preserve and have preserved a corresponding relation in the module, utilize described corresponding relation can obtain the actual physics memory information that client operating system uses; And acquisition module can be determined to obtain the first corresponding actual physics internal memory of first client operating system of indicating in the instruction with described state according to this corresponding relation.
Two kinds of forms of expression of this corresponding relation are as follows:
The actual physics internal memory of client operating system ID to should client operating system using; Or
The virtual memory of client operating system ID to should client operating system using, the corresponding actual physics internal memory of this virtual memory.
Can both determine the actual physics internal memory that client operating system uses by any one corresponding relation.
Below above-mentioned VMM is elaborated.
VMM is responsible for the management work of all GOS, suppose when GOS A starts, save as 256M in the physical vlan of distribution module for GOS A distribution, and the physical vlan internal memory can not make the real operation of GOS A, the operation of GOS A need be based upon on the basis of actual physical internal memory, therefore, VMM need arrive the actual physics internal memory with the physical vlan memory-mapped of distributing, this moment is by setting up this physical vlan memory-mapped to the actual physics internal memory the mapping relations between the two, by such processing, though what GOS A saw may be continuous 256 MB of memory, what GOS A used in operational process is the actual physics internal memory corresponding with this 256M virtual memory.
After by above-mentioned processing, need be for the mapping relations between this GOS A preservation physical vlan internal memory and the actual physics internal memory, so that follow-up analysis.
In some periods, GOS (can be GOS A, also can be other GOS) need obtain the system state of GOS A, and send a state to VMM and obtain instruction this moment, and state obtains the sign that comprises GOS A in the instruction.
VMM is according to the sign of the GOS A in the instruction, obtain and the physical vlan internal memory of the corresponding preservation of the sign of GOS A and the mapping relations between the actual physics internal memory, obtain the actual physics internal memory that writes down in the mapping relations, the actual physics internal memory that obtain this moment is exactly the actual use of a GOS A physical memory, it can be one section internal memory, as the 0-256M in the physical memory of main frame, also may be that the multistage physical memory is formed, as these two sections of 0-128M and 256-384M.
After obtaining the physical memory of the actual use of GOS A, read through model just can read the data message in the physical memory of the actual use of this GOS A, and utilizes writing module to be written to actual I/O equipment (but as hard disk imprinting disk, USB flash disk, portable hard drive etc.).
In case GOS breaks down, the reason of bringing fault might be the data self in the physical memory, also might be the distribution situation of data in physical memory, only can obtain data self in the prior art, and can't obtain the distribution of data in the actual physics internal memory, so its limitation is arranged in the fault analysis current political situation, and utilize the embodiment of the invention, not only can obtain data, can also obtain the distribution of data in the actual physics internal memory, therefore help fault analysis more.
Simultaneously, for prior art, the generation of DUMP file needs DUMP device drives spin lock to open, and needs to load the DUMP device drives, otherwise can't produce the DUMP file, in case and GOS breaks down, when above-mentioned condition is false, just can't obtain the DUMP file, and for the embodiment of the invention, can utilize other normal GOS to send instruction, comprise in this instruction that the sign of fault GOS gets final product, so the situation of DUMP file can not occur to generate to VMM.
Simultaneously and since cancelled in the embodiment of the invention to GOS whether loading equipemtn drive in time restriction, the time of obtaining internal memory can be faster.
The dummy machine system of the embodiment of the invention comprises client operating system, virtual machine monitor, wherein:
Be provided with state in the described client operating system and obtain instruction sending module, be used for sending the state that comprises the client operating system sign and obtain instruction to VMM;
