Detailed Description
The invention is described in further detail below with reference to specific embodiments.
The virtualization platform is composed of a plurality of virtual machines built on a plurality of hosts, and manages the virtual machines by a heterogeneous method of virtualizing a resource pool.
The steps of performing the heterogeneous method of virtualizing a resource pool when building the heterogeneous resource pool are as follows.
And a characteristic value obtaining step: the cpu characteristic value of each host is acquired using the cpu id instruction.
A characteristic instruction set acquisition step: and calculating the intersection of each field of all the acquired host cpu characteristic values, and recording the intersection as a characteristic instruction set.
A virtual machine characteristic configuration step: the property instruction set is configured as a virtual machine property cpufeatureset to all virtual machines in the resource pool.
The heterogeneous method for virtualizing the resource pool, which is realized by the above steps, is equivalent to shielding partial functions of a cpu host of a high version when the resource pool is built, and the virtual machines run by each host keep the same virtual machine characteristic cpu feature, that is, the virtual machines run on any host are all equal, so that all the virtual machines on the heterogeneous resource pool can be migrated from one host to another smoothly without execution and running differences among different hosts, and a plurality of sets of management systems are not required to be built to manage all the virtual machines and the hosts on which the virtual machines work.
The virtual machine platform executes the heterogeneous method of the virtualized resource pool, and controls all virtual machines in a mode of automatically calculating cpu characteristic instruction sets of the virtual machines, and the specific steps are detailed as follows.
Firstly, a characteristic value acquisition step is executed, and a cpu characteristic value of a host running each virtual machine is acquired by using a cpu id instruction. The specific steps for obtaining the cpu characteristic values of the hosts are as follows: the feature fields in the xe host-cpu-info of the host are obtained through the cpu id instruction, and the feature values of the host recorded by the feature fields are extracted.
The cpu id instruction obtains input parameters from the eax register, and then outputs the output parameters to the registers eax, ebx, ecx and edx. The cpu feature values (cpu features) of all hosts obtained using the cpu id instruction are returned to the eax, ebx, ecx, and edx registers, as are the cpu feature values: 17cbfbff-95ba2223-2993 fbff-00000003-.
Take the cpu eigenvalue obtained above as an example.
A first stage: the input parameter eax is 0x1, ecx is cleared, and the output parameter edx// cpu features;
and a second stage: the input parameter eax is 0x1, ecx is cleared, and the output parameter ecx// cpu features;
a third stage: the input parameter eax is 0x80000001, ecx is cleared, and the output parameter edx// cpu extra features;
a fourth stage: the input parameter eax is 0x80000001, ecx is cleared, and the output parameter ecx// cpu extra features;
a fifth stage: input parameters eax is 0xd, ecx is 1, output parameters eax// The size in bytes of The XSAVE area connecting all enabled by XCRO | IA32_ XSS;
a sixth stage: the input parameter eax is 0x7, ecx is 0, and the output parameter ebx// Structured Extended features Flags and execution Leaf;
a seventh stage: the input parameter eax is 0x7, ecx is 0, and the output parameter ecx// Structured Extended features Flags and execution Leaf;
an eighth stage: the input parameter eax is 0x80000007, ecx is cleared, and the output parameter edx// Bit 08 is Invariant TSC available if 1;
a ninth stage: the input parameter eax is 0x80000008, ecx is cleared, and the output parameter ebx// 0.
And performing union operation on all the return values executed by the cpu 0x1 and the cpu 0x80000001 of the physical cpu of the host according to the same register value, wherein the obtained union is used as a cpu instruction set of the host.
And then executing a characteristic instruction set acquisition step, calculating the intersection of each field of all the acquired host cpu characteristic values, specifically, identifying the same field in each host cpu instruction set, and recording all the identified same fields as the characteristic instruction set of the resource pool.
In the case of different models of cpus or the same model of cpu in different configurations, there will be a difference in the obtained feature values, such as the following two cpu values:
17c9cbf5-f6f83203-2191cbf5-00000123-00000007-018c0b39-00000000-00000000-00000000（1）；
17cbfbff-f7fa3223-2d93fbff-00000123-0000000f-019c4fbb-00000008-00000000-00000000（2）；
if the two cpus are combined into a resource pool, the intersection of each field of the two cpus is calculated to obtain the intersection
17c9cbf5-f6f83203-2191cbf 5-00000123-.
And finally, executing a virtual machine characteristic configuration step, calling a characteristic instruction set stored in the Hypervisor to serve as the virtual machine characteristic cpufeatureset to be configured to all virtual machines in the resource pool. When the cpu id instruction vmexit executed inside the virtual machine exits to the Hypervisor, the Hypervisor simulates the execution of the cpu id of the virtual machine, and when the virtual machine queries the cpu features, the cpu id return value of the actual physical cpu and the calculated corresponding field are subjected to and operation, and the result is used as the return value of the cpu id of the virtual machine.
When the resource pool is constructed, the intersection of each field of cpu characteristic values of all hosts, namely a characteristic instruction set, is calculated, and then the characteristic instruction set obtained by calculation is configured to all virtual machines in the resource pool as virtual machine characteristic cpufatureset, which is equivalent to shielding partial functions of high-version cpu hosts, and the virtual machines operated by all hosts keep the same virtual machine characteristic cpufatureset, namely the virtual machines are operated on any host in a peer-to-peer manner, so that all virtual machines on the heterogeneous resource pool can realize online smooth migration from one host to another without execution operation difference among different hosts, and a plurality of sets of management systems are not required to be constructed to manage all the virtual machines and the hosts on which the virtual machines operate.
The virtual platform executes the above-mentioned heterogeneous method for virtualizing the resource pool under the following three conditions: a new host applies for adding into the resource pool; a host exits the resource pool; and the host in the resource pool is reconnected after the host in the resource pool is restarted.
Under the condition that a new host applies for adding into a resource pool, executing the step of adding the new host into the pool firstly: acquiring information of a new host applied to the pool, extracting a cpu characteristic value of the new host according to a feature field in the xehost-cpu-info in the acquired information, calculating an intersection of the cpu characteristic value of the new host and a characteristic instruction set, and distributing the calculated intersection to each virtual machine as a new characteristic instruction set.
In addition, a pre-check step is executed before the new host pooling step: and acquiring a cpu characteristic value of a new host currently applied to the pool, judging whether the acquired cpu characteristic value deviates (deviates upwards or downwards) from a characteristic instruction set of the resource pool to a preset degree, and if so, sending a prompt.
In the pre-checking step, if the downward deviation reaches the preset degree as a result of the judgment, it indicates that the new host version is lower and the feature value difference with the host in the resource pool is too large, and after the cpu host of the lower version is added into the resource pool and enters the cpu host resource pool of the higher version, the cpu host may not be started after being shut down
In the pre-checking step, if the judgment result is that the upward deviation reaches the preset degree, it indicates that the new host version is higher and the feature value difference with the host in the resource pool is too large, and the cpu host of the higher version is added into the resource pool to the cpu resource pool of the lower version, so that the new characteristic of the cpu host of the higher version cannot be exerted, and the new host is not suitable for being added into the resource pool. However, in order to avoid that the current resource pool urgently needs the resources of the new host, it is necessary to determine whether the total amount of the resources of the resource pool occupied by the resource usage of the current resource pool reaches a preset degree, and if the determination result is yes, the pre-checking step does not send a prompt, but adds the new host into the resource pool.
The hardware identification step is executed before the step of entering the new host into the pool is executed, whether the hardware configuration (such as the number of network cards and the HBA card speed) of the host newly applying for adding into the resource pool deviates from the preset standard configuration to reach the preset degree (such as lower than 70 percent of the standard configuration) is judged, and if the judgment result is yes, a prompt is sent. The standard configuration is the average of the hardware configurations of all hosts already in the resource pool.
Wherein, in the step of obtaining the characteristic value and the step of entering the pool by the new host, the method further comprises a step of detecting the configuration executed before obtaining the cpu characteristic value: judging whether closed cpu characteristics exist in the BIOS configuration of the host, if so, adding the host into the resource pool, which may result in that virtual machines running on all hosts of the whole resource pool cannot use these cpu characteristics, and if the host is turned off and vt-x is closed, then all hosts in the resource pool cannot run full virtual machines, so the virtualization platform sends a prompt to prompt an administrator/user to check whether the cpu characteristics currently in the closed state can be opened.
The hosts added into the resource pool all adopt CPUs of the same manufacturer, the situation that the CPUs of Intel and AMD are used in a mixed mode cannot occur, the same virtualization management center version is installed on all the hosts, and meanwhile the patch of each host is kept consistent.
The above embodiments are only embodiments of the present invention, and the scope of protection is not limited thereto. The insubstantial changes or substitutions will now be made by those skilled in the art based on the teachings of the present invention, which fall within the scope of the claims.
