The virtual machine of machine memory safe dose；
If (e) Host Idle Memory Allocation to all virtual machine free memories under it are above the virutal machine memory peace
When full dose, then adjustment terminates；
If (f) Host Idle Memory Allocation is complete, still there is virtual machine free memory to be lower than the virutal machine memory safe dose,
Then host is alarmed.
Preferably, in (d) step, Host Idle memory is preferentially distributed in described (4) step and is extracted memory
Virtual machine.
Preferably, the warning message in described (6) step and (f) step is sent to system manager.
Compared with prior art, the present invention have it is following the utility model has the advantages that
(1) monitoring host computer memory is based on safe dose, reduces dynamic adjustment frequency, and virtual machine is made to have sufficient memory reply
The request of burst；
(2) setting of virutal machine memory safe dose can ensure the normal operation of virtual machine；
(3) when host memory or virutal machine memory are lower than safe dose, administrator can be notified by alarm in time.
Detailed description of the invention
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other feature of the invention,
Objects and advantages will become more apparent upon:
Fig. 1 is flow chart of the method for the present invention.
Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection scope.
Referring to attached drawing 1, the memory dynamic adjusting method of cloud desktop host and virtual machine is realized by following basic step:
Step 1: monitoring memory；Monitoring host computer memory and virtual machine free memory situation.
Step 2: adjustment memory；If Host Idle memory is lower than safe dose, the free memory of virtual machine thereon is extracted, it is such as main
Machine free memory is higher than safe dose, and memory is returned to virtual machine, host memory and virutal machine memory is finally reached and is all higher than peace
Full dose.
If host memory is lower than safe dose, inquiry free memory is higher than the virtual machine of safe dose, extracts its memory, confirmation master
Whether machine free memory is higher than safe dose, is, adjustment terminates；Otherwise 3 are gone to step.
If host memory is higher than safe dose, the plan of giving back is formulated, inquires decimated virtual machine, calculating need to give back interior
It deposits, preferentially meets the virtual machine that memory is lower than safe dose, other virtual machines give back the memory that a part has extracted, and return if success
Otherwise also virutal machine memory goes to step 3.
Step 3: alarm；Based on message informing administrator.
Detailed step includes host memory dynamic adjusting method, and steps are as follows:
(1) virutal machine memory safe dose and host memory safe dose are set；
(2) start the virtual machine of host and its lower configuration；
(3) monitoring host computer memory, if Host Idle memory is lower than the host memory safe dose,
(4) virutal machine memory under the host is monitored, the void that free memory is greater than the virutal machine memory safe dose is extracted
The spare memory of quasi- machine；
(5) if Host Idle memory is higher than the host memory safe dose, adjustment terminates；Otherwise return step (4)
It is completed until all virtual machines are all monitored under the host；
(6) if Host Idle memory is still below the host memory safe dose, host is alarmed,
Steps are as follows for virutal machine memory dynamic adjusting method:
(a) virutal machine memory safe dose and host memory safe dose are set；
(b) start the virtual machine of host and its lower configuration；
(c) monitoring host computer memory, if Host Idle memory is higher than the host memory safe dose,
(d) virutal machine memory under the host is monitored, host spare memory is distributed to free memory virtual lower than described
The virtual machine of machine memory safe dose；
If (e) Host Idle Memory Allocation to all virtual machine free memories under it are above the virutal machine memory peace
When full dose, then adjustment terminates；
If (f) Host Idle Memory Allocation is complete, still there is virtual machine free memory to be lower than the virutal machine memory safe dose,
Then host is alarmed.
In (d) step, Host Idle memory preferentially distributes to the virtual machine that memory is extracted in described (4) step.
Warning message in (6) step and (f) step is sent to system manager.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
