It is (SuSE) Linux OS to unite, and those skilled in the art can be with reasonable prediction to other operating systems according to respective operating system reality
The virtual hardware environment (including processor, internal memory, I/O equipment) of border hardware and adaptability is selected.
The so-called medium that can configure virtual machine including but not limited to PC, server, computer cluster server, calculating section
Point, virtual machine, distributed memory system or other there is the electronic installation of logical operation function, in the present embodiment, should
The medium that virtual machine can be configured selects server, and the explanation of presenting a demonstration property.
In the existing calculating of traditional establishment virtual machine, request of the backstage in the establishment virtual machine for receiving user's transmission
Afterwards, in the various virtual resources formed by virtualization by Intel Virtualization Technology (such as Hyper-V) by server, with shape
Into resource pool, and ask to create virtual machine to respond the request to create of user temporarily according to what user sent.
However, in the present embodiment, the medium (such as server) of virtual machine can be being configured in advance, both can be pre-
First encapsulate all resources (server based on certain specification forms the maximum resource of supporting various applications) are advance or match somebody with somebody
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, will be interior
Resource Encapsulation is deposited for 1G, 2G, 3G to 10G, other support the various resources of virtual machine health operation, and so on, and step by step
Increment is set；Or 1 CPU and 1G internal memories are encapsulated as a configurations, another configuration will be saved as in 2 CPU and 2G
Increased configurations, so as to form multiple configurations.Linearly increasing logical relation can be formed between each configurations,
And integrated or combined during the later stage creates virtual machine, please with the virtual machine creating for flexibly being sent according to user
Ask establishment to meet the virtual machine of request, prevent the request of the establishment virtual machine that backstage sends according to user from being taken out from resource pool temporarily
Take CPU, internal memory etc. to configure and cause backstage when creating virtual machine congestion or cannot respond to the problem of request, in reduction system
Computing cost after line, so as to cause extra computing cost to backstage when reducing interim establishment virtual machine；Meanwhile, can also drop
The expense of the load equalizer in low clouds platform.
Certainly, also can as Fig. 3 the medium that will configure virtual machine encapsulation in advance or configure underlying virtual machine step by step
101st, 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
It is used to respond the minimalist configuration corresponding to the request of user's establishment virtual machine.
Separately, all underlying virtual machines of cloud platform may be selected and creates total equipment collection (equivalent to above-mentioned underlying virtual machine), with
Underlying virtual machine 101 for minimize underlying virtual machine and as the drawing template establishment or configuration template of other underlying virtual machines.
The total equipment collection is understood to mentioned above by the configuration comprising CPU and internal memory after encapsulation.These total equipment collection
The establishment of virtual machine is supported for the later stage.
Next we make briefly to explain so that virtualization software selects qemu as an example in the detailed process for creating total equipment collection
State.
Above-mentioned total equipment collection includes：Monitor (monitor), serial ports, CPU, internal memory, real-time clock (rtc) and right
Claim multiprocessing structure virtual cpu group (SMP) etc., and adaptation Sexual behavior mode can be made according to cloud platform setting.Specifically, create this being total to
There is 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 CPU number in underlying virtual machine, and specified maxcpus is intended that and starts in underlying virtual machine
Dynamically configuring (2,4,8 or more CPU are selected) according to client afterwards 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 according to the already installed system disk startup underlying virtual machine of selection, and customization is created as follow-up
Change the drawing template establishment of virtual machine.
In the present embodiment, the establishment virtual machine that is sent in order to avoid user please seek to achieve breakthrough that this can configure virtual machine
The total equipment collection that is formed of medium or resource the upper limit, after execution of step S1, can also carry out to being rung to user
The step of virtual machine configuration upper limit answered is configured.Upper limit configuration includes CPU configurations, maximum memory configurations, the maximum of maximum
Band width configuration, optimal monitor arrangement, maximum disk configuration, optimal real-time clock configuration and optimal outer establishing
The resource such as put.After underlying virtual machine is configured to finish, can close underlying virtual machine can not also close underlying virtual machine.
Then, step S2 is performed, is obtained and is preserved state when underlying virtual machine is configured.Preferably, in this embodiment party
In formula, step S2 also includes obtaining operation system state file, operating system daily record that configuration forms multiple underlying virtual machines
(OS log file) or disk file system (disk file system).State when the underlying virtual machine is configured
Including：CPU state, internal storage state, bandwidth status, Disk State, real-time clock state or peripheral state.Preferably, the step
Rapid S3 also includes：State when operation system state file and underlying virtual machine according to underlying virtual machine are configured, starts
Virtual machine.
It should be noted that in the present embodiment, so-called " state " refers to interior for internal memory (or virtual memory)
Snapshot is deposited, refers to disk snapshot for disk (or virtual disk).When snapshot operation is created, to create underlying virtual machine
Built-in system restoration point as a example by, it performs code and is accordingly：(qemu)savevm xxc.
In step s 2, after the configuration of underlying virtual machine is finished, also including the operating system shape of preservation underlying virtual machine
State file and the step of close underlying virtual machine, further to reduce the computing cost on backstage.
Then, step S3, the request of traversal virtual machine creating are performed, with underlying virtual machine be template loading increment configure or
Person's unloading configuration, until request is performed and finishes, and responds user.
By the underlying virtual machine for being pre-configured with or being pre-created in step sl not can completely expire asking for user
Ask, while the efficiency in order to improve later stage virtual machine creating and deployment, it is to avoid be pre-configured with the excessive underlying virtual machine of quantity,
In the present invention, an advance underlying virtual machine with source minimalist configuration in the medium for configure virtual machine can be possible to, in one
Deng the underlying virtual machine of configuration and the underlying virtual machine of a high configuration, the relation of increment configuration is formed between three.
During the virtual machine creating in later stage, when for the performance that general user sends not being that virtual machine creating very high is asked, can be straight
Connect the virtual machine based on above-mentioned minimalist configuration and with its be template loading increment configure, so as to from above the step of S1 formed in
Total equipment collection or suitable configuration (or resource) is chosen referred to as in configurations, so as to further be packaged into one
The virtual machine of user's request is disclosure satisfy that, to respond user.
Specifically, the order for starting increment configuration is：-loadvm xxc.
It is assumed that the configuration of user only increased internal memory usage amount on the template virtual machine of minimalist configuration, it is 2G,
Dynamically increase internal memory in qemu monitor, its 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 of minimalist configuration is shown below carries out loading increment and configure code before and after this process.
A. before the configuration of loading increment
[root@localhost~] #cat/proc/meminfo
B. loading increment is matched somebody with somebody and is postponed
[root@localhost~] #cat/proc/meminfo
So far, the virtual machine creating for meeting user's request is finished.
In the present embodiment, by configuring one or more underlying virtual machine configured in increment step by step, and lead to
The mode of loading increment configuration is crossed, the virtual machine of user's request to create is met to be formed, greatly improve the establishment of virtual machine
Efficiency.
On the other hand, because 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 when associated by the request for creating virtual machine transmitted by certain user
Virtual machine configuration more than minimalist configuration underlying virtual machine when, backstage can be from immediate with what the user's request matched
Chosen in the underlying virtual machine of configuration, and unload the operation of configuration.
For example, as follows to the code of the underlying virtual machine reduction memory configurations of immediate configuration.
(qemu) device_del dimm1//remove virtual memory from underlying virtual machine；
(qemu) object_del mem1//from virtualization software are moved and are removed memory configurations object；
Specifically, configuration can be step by step reduced in units of GB, MB or KB, it is immediate with user's request so as to match
Virtual machine, and to user response, so as 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 of addition is disk1 to virtualization software.
(qemu) device_add virtio-blk-pci, drive=disk1, id=myvirtio1
// name of virtualization software is added to for the block device of disk1 is added to virtual machine facility, equipment identification
Entitled myvirtio1.
(qemu)device_del disk1
// block device of entitled disk1 is removed from virtual machine and virtualization software.
As the further optimization of present embodiment, also include in step S2：Gone through according to the request to create that user sends
Concordance list is set up in Records of the Historian record, and a virtual machine of the request to create for meeting user's transmission is matched by concordance list and use is responded
Family.Concordance list recordable user create, start, running and closing the use habit of virtual machine, and forms log file.Record text
Part can be associated with the underlying virtual machine that is created in step S1, and when user initiates request operation again by the index
Table is directly created and starts virtual machine, so as to further increase the efficiency that user creates virtual machine.
