Fig. 2 is the schematic flow sheet of the method for the embodiment of the present invention.
Detailed description of the invention
The virtual machine monitor of the embodiment of the present invention, in dummy machine system and client operation system state acquiring method, in the process creating GOS, VMM is recorded as the virtual memory of GOS distribution, and the corresponding relation between virtual memory and actual physics internal memory, when needing the state obtaining GOS, according to the corresponding relation between virtual memory and actual physics internal memory, obtain the related data of record in physical memory, be saved in DUMP file.
Embodiments of the invention dummy machine system includes physical hardware, VMM and GOS, wherein:
As it is shown in figure 1, described VMM includes:
Distribution module, for distributing virtual memory for client operating system;
Mapping block, for setting up the mapping relations between described virtual memory and actual physics internal memory;
Preserve module, preserve the mark of described client operating system and described mapping relations for correspondence;
First acquisition module, for, after the state that receives obtains instruction, identifying according to the client operating system in described instruction, it is determined that the first mapping relations corresponding with described client operating system mark in described preservation module;
Second acquisition module, for obtaining the first actual physics internal memory of record in described first mapping relations;
First data message read through model, for reading the first data message in described first actual physics internal memory;
First data message writing module, for writing true I/O equipment by the first data message in described first actual physics internal memory.
Certainly, this data message writing module is unnecessary in some cases, only utilizes the first data message to carry out subsequent analysis at needs and uses just needs.
Certainly, simpler is, preserve the mark of the module directly described client operating system of corresponding preservation and the actual physics internal memory (namely preserving the corresponding relation between client operating system and its actually used actual physics internal memory) that this client operating system is actually used, first acquisition module and the second acquisition module unite two into one, and directly obtain the first actual physics internal memory of client operating system.
Two kinds of implementations of summary, it is found that preserve in module and save a corresponding relation, utilize described corresponding relation can obtain the actual physics memory information that client operating system uses; And acquisition module can determine according to this corresponding relation and obtains, with described state, the first actual physics internal memory that in instruction, the first client operating system of instruction is corresponding.
Two kinds of forms of expression of this corresponding relation are as follows:
Client operating system ID to should client operating system use actual physics internal memory; Or
Client operating system ID to should client operating system use virtual memory, this virtual memory correspondence actual physics internal memory.
The actual physics internal memory that client operating system uses can be determined by any one corresponding relation.
Below above-mentioned VMM is described in detail.
VMM is responsible for the management work of all GOS, assuming that when GOSA starts, distribution module is save as 256M in the GOSA physical vlan distributed, and physical vlan internal memory can not make GOSA really behave, GOSA runs on the basis needing to be based upon the physical memory of reality, therefore, VMM needs the physical vlan internal memory of distribution is mapped to actual physics internal memory, mapping relations therebetween are set up now by being mapped on actual physics internal memory by this physical vlan internal memory, by such process, although what GOSA saw is probably continuous print 256 MB of memory, but GOSA uses the actual physics internal memory corresponding with this 256M virtual memory in running.
After by above-mentioned process, it is necessary to preserve the mapping relations between physical vlan internal memory and actual physics internal memory for this GOSA, in order to follow-up analysis.
In some period, GOS (can be GOSA, it is also possible to be other GOS) needs to obtain the system mode of GOSA, now sends a state to VMM and obtains instruction, and state obtains the mark that instruction includes GOSA.
The VMM mark according to the GOSA in instruction, obtain the mapping relations between the physical vlan internal memory and the actual physics internal memory that identify corresponding preservation of GOSA, obtain the actual physics internal memory of record in mapping relations, the actual physics internal memory now obtained is exactly the actually used physical memory of GOSA, it can be one section of internal memory, 0-256M in the physical memory of main frame, it is also possible to multistage physical memory forms, such as 0-128M and 256-384M these two sections.
After obtaining the actually used physical memory of GOSA, read through model just can read the data message in the actually used physical memory of this GOSA, and utilize writing module be written to reality I/O equipment (as hard disk, can imprinting disk, USB flash disk, portable hard drive etc.).
Once GOS breaks down, the reason bringing fault is likely to be the data in physical memory self, it could also be possible that the distribution situation that data are in physical memory, prior art is only capable of obtain data self, and data distribution in actual physics internal memory cannot be obtained, so having its limitation in the accident analysis current political situation, and utilize the embodiment of the present invention, not only can obtain data, it is also possible to obtain data distribution in actual physics internal memory, therefore advantageously in accident analysis.
Simultaneously, for prior art, the generation of DUMP file needs DUMP device drives spin lock to open, and needs to load DUMP device drives, otherwise cannot produce DUMP file, and once GOS breaks down, when above-mentioned condition is false, DUMP file just cannot be obtained, and for the embodiment of the present invention, the normal GOS that can utilize other sends instruction to VMM, and this instruction includes the mark of fault GOS, so not havinging the situation that cannot generate DUMP file.
Simultaneously as eliminate in the embodiment of the present invention GOS, whether loading equipemtn drives restriction in time, and the time obtaining internal memory can be faster.
The dummy machine system of the embodiment of the present invention includes client operating system, virtual machine monitor, wherein:
The state that is provided with in described client operating system obtains instruction sending module, obtains instruction for sending the state including client operating system mark to VMM;
Described VMM includes:
Distribution module, for distributing virtual memory for described client operating system;
Mapping block, for setting up the mapping relations between described virtual memory and actual physics internal memory;

Certainly, simpler is, preserving the mark of the module directly described client operating system of corresponding preservation and the actual physics internal memory that this client operating system is actually used, the first acquisition module and the second acquisition module unite two into one, and directly obtain the first actual physics internal memory of client operating system.
Certainly, it is analyzed to obtain more information further, the VMM of the embodiment of the present invention also includes:
Second data message read through model, is used for the second data message reading in the depositor of physical cpu;
Second data message writing module, for writing true I/O equipment by described second data message.
In a particular embodiment of the present invention, owing to GOS needs mutual with CR3 depositor when starting, so VMM monitors the start-up course of GOS by intercepting and capturing CR3 depositor.
The method of the embodiment of the present invention is as in figure 2 it is shown, include:
Step 21, when the first client operating system starts, for described first client operating system distribution virtual memory;
Step 22, sets up the mapping relations between described virtual memory and actual physics internal memory;
