The virtual hardware environment (including processor, memory, I/O equipment) of border hardware and adaptability is selected.
The so-called medium that can configure virtual machine includes but is not limited to PC, server, computer cluster server, calculates section
Point, virtual machine, distributed memory system or other electronic devices with logical operation function in the present embodiment should
The medium that virtual machine can be configured selects server, and presenting a demonstration property explanation.
In the existing calculating of traditional creation virtual machine, from the background in the request for the creation virtual machine for receiving user's transmission
Afterwards, various virtualization resources are being formed by by virtualization by virtualization technology (such as Hyper-V) by server, with shape
Virtual machine temporarily is created to respond the request to create of user at resource pool, and according to the request that user sends.
However, in the present embodiment, it can be in advance in the medium (such as server) that can configure virtual machine, it both can be pre-
First all resources (server based on certain specification, which is formed, supports the maximum resources of various applications) are encapsulated or matched in advance
It is set to the child resource with individual feature.For example, the cpu resource in resource pool is encapsulated as 1,2,3 to 10, it will be interior
Depositing Resource Encapsulation is the various resources that 1G, 2G, 3G are run to 10G, other support virtual machine health, and so on, and step by step
Increment setting；Or 1 CPU and 1G memory are encapsulated as a configurations, another configuration will be saved as in 2 CPU and 2G
Increased configurations, to form multiple configurations.Linearly increasing logical relation can be formed between each configurations,
And integrated or combined during creating virtual machine in the later period, flexibly to be asked according to the virtual machine creating that user sends
Creation is asked to meet the virtual machine of request, the request for the creation virtual machine for preventing backstage from being sent according to user is temporarily taken out from resource pool
Take CPU, memory etc. configure and when creating virtual machine to causing congestion from the background or cannot respond to request the problem of, in reduction system
Computing cost after line, thus to causing additional computing cost from the background when reducing interim creation virtual machine；Meanwhile it can also drop
The expense of load balancer in low clouds platform.
Certainly, can also as Fig. 3 the medium for configuring virtual machine is encapsulated in advance or is configured step by step underlying virtual machine
101, underlying virtual machine 102 (remaining summary) ... underlying virtual machine 10n, to constitute n underlying virtual machine.N underlying virtual machine it
Between configuration form increment relation.For example, the CPU of underlying virtual machine 101 is configured to 1, memory configurations are 1G (remaining summary), basis
The CPU of virtual machine 102 is configured to 2, and memory configurations are 2G (remaining summary).Wherein, every configuration of underlying virtual machine 101 is set as
Minimalist configuration corresponding to the request of virtual machine is created to respond user.
In addition, all underlying virtual machines of cloud platform, which may be selected, creates shared equipment collection (being equivalent to above-mentioned underlying virtual machine), with
Underlying virtual machine 101 is the underlying virtual machine minimized and drawing template establishment or configuration template as other underlying virtual machines.
The shared equipment collection is understood to the configuration comprising CPU and memory described above after encapsulation.These shared equipment collection
The creation of virtual machine is supported for the later period.
Next we briefly explain so that virtualization software selects qemu as an example in the detailed process work for creating shared equipment collection
It states.
Above-mentioned shared equipment collection includes: monitor (monitor), serial ports, CPU, memory, real-time clock (rtc) and right
Claim multiprocessing structure virtual cpu group (SMP) etc., and can be arranged according to cloud platform and make adaptability selection.Specifically, it is total to create this
Have the main code of equipment collection as follows:
-cpu qemu64
- chardev socket, id=charmonitor, path=./qemu.monitor, server, nowait
- mon chardev=charmonitor, id=monitor, mode=control
- rtc base=utc, driftfix=slew
-machine pc
- m 1G, slots=3, maxmem=4G
- smp 1, maxcpus=64, sockets=64, cores=1, threads=1
Wherein, smp reflects the CPU number in underlying virtual machine, and specified maxcpus is intended that be started in underlying virtual machine
(2,4,8 or more CPU select) is dynamically configured according to client afterwards and increases CPU number, is up to
64 CPU.- m reflects the Installed System Memory for running the underlying virtual machine, and maxmem is to run the underlying virtual machine to can configure most
Big memory size.Then it according to the already installed system disk startup underlying virtual machine of selection, and is customized as subsequent creation
Change the drawing template establishment of virtual machine.
In the present embodiment, the creation virtual machine sent in order to avoid user please seek to achieve breakthrough that this can configure virtual machine
Medium be formed by the upper limit of shared equipment collection or resource, after executing the step S1, can also carry out opposite user and ring
The step of virtual machine configuration upper limit configuration answered.Upper limit configuration includes maximum CPU configuration, maximum memory configurations, maximum
Band width configuration, optimal monitor arrangement, the configuration of maximum disk, the configuration of optimal real-time clock and optimal outer establishing
The resources such as set.After underlying virtual machine is configured, can close underlying virtual machine can not also close underlying virtual machine.
Then, step S2, acquisition are executed and saves state when underlying virtual machine is configured.Preferably, in this embodiment party
In formula, step S2 further includes operation system state file, the operating system log for obtaining configuration and forming multiple underlying virtual machines
(OS log file) or disk file system (disk file system).State when the underlying virtual machine is configured
It include: CPU state, internal storage state, bandwidth status, Disk State, real-time clock state or peripheral state.Preferably, the step
Rapid S3 further include: state when being configured according to the operation system state file of underlying virtual machine and underlying virtual machine, starting
Virtual machine.
It should be noted that in the present embodiment, so-called " state " refers to interior for memory (or virtual memory)
Snapshot is deposited, refers to disk snapshot for disk (or virtual disk).When creating snapshot operation, to create underlying virtual machine
Built-in system restoration point for, execute code accordingly are as follows: (qemu) savevm xxc.
It in step s 2, further include the operating system shape for saving underlying virtual machine after the configuration of underlying virtual machine finishes
State file and the step of close underlying virtual machine, to further decrease the computing cost on backstage.
Then, execute step S3, traverse virtual machine creating request, using underlying virtual machine be template load increment configure or
Person unloads configuration, until request is performed and finishes, and responds user.
Since the underlying virtual machine for being pre-configured with or being pre-created in step sl is not that can expire asking for user completely
It asks, while in order to improve the efficiency of later period virtual machine creating and deployment, avoiding being pre-configured with the excessive underlying virtual machine of quantity,
In the present invention, it can will configure in the medium of virtual machine and to match a underlying virtual machine of source minimalist configuration in advance, in one
The underlying virtual machine of configurations and the underlying virtual machine of a high configuration are waited, forms the relationship of increment configuration between three.?
It, can be straight when not being the request of very high virtual machine creating for the performance that general user sends during the virtual machine creating in later period
It connects the virtual machine based on above-mentioned minimalist configuration and loads increment configuration using it as template, thus formed in the step S1 above
Shared equipment collection or suitable configuration (or resource) is chosen referred to as in configurations, to further be packaged into one
It can satisfy the virtual machine of user's request, to respond user.
Specifically, the order of starting increment configuration are as follows:-loadvm xxc.
It is assumed that the configuration of user only increases memory usage amount on the template virtual machine of minimalist configuration, it is 2G,
Dynamic increases memory in qemu monitor, and code is as follows:
(qemu) object_add memory-backend-ram, id=mem1, size=1G
(qemu) device_add pc-dimm, id=dimm1, memdev=mem1.
The underlying virtual machine that minimalist configuration is shown below carries out load increment and configures code before and after this process.
A. before the configuration of load increment
[root@localhost~] #cat/proc/meminfo
B. load increment, which is matched, postpones
[root@localhost~] #cat/proc/meminfo
So far, the virtual machine creating for meeting user's request finishes.
In the present embodiment, it is in the underlying virtual machine of increment configuration by configuring one or more step by step, and leads to
The mode of load increment configuration is crossed, to form the virtual machine for meeting user's request to create, greatly improves the creation of virtual machine
Efficiency.
On the other hand, since the request to create of client is personalized, if increasing the quantity of underlying virtual machine simply
Also result in the increase of hind computation expense.Therefore, if worked as associated by the request of creation virtual machine transmitted by some user
Virtual machine configuration be more than minimalist configuration underlying virtual machine when, from the background can from the user request match it is immediate
It is chosen in the underlying virtual machine of configuration, and carries out the operation of unloading configuration.
For example, the code for reducing memory configurations to the underlying virtual machine of immediate configuration is as follows.
(qemu) device_del dimm1//remove virtual memory from underlying virtual machine；
(qemu) object_del mem1//from virtualization software, which is moved, removes memory configurations object；
Specifically, configuration can be reduced step by step as unit of GB, MB or KB, to match immediate with user's request
Virtual machine, and to user response, to effectively avoid the waste of memory source in resource pool.
For example, the code for reducing disk configuration to the underlying virtual machine of immediate configuration or increasing disk configuration is as follows
It is shown.
(qemu) drive_add 0if=none, file=/tmp/test.img, format=raw, id=disk1//
One piece of RAW format disc test.img name is added as disk1 to virtualization software.
(qemu) device_add virtio-blk-pci, drive=disk1, id=myvirtio1
// be added to the block device that the name of virtualization software is disk1 and be added to virtual machine facility, equipment identification
Entitled myvirtio1.
(qemu)device_del disk1
// remove the block device of entitled disk1 from virtual machine and virtualization software.
As advanced optimizing for present embodiment, in step S2 further include: the request to create sent according to user is gone through
Concordance list is established in Records of the Historian record, and is matched a virtual machine of the request to create for meeting user's transmission by concordance list and responded use
Family.Concordance list can record user's creation, starting, operation and the use habit for closing virtual machine, and form record file.Record text
Part can be associated with the underlying virtual machine created in step S1, and when user initiates request operation again by the index
Table directly creates and starts virtual machine, to further improve the efficiency that user creates virtual machine.
