To further explain the technical means and effects of the present invention adopted to achieve the intended purpose, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.
The first embodiment of the present invention provides a remote heterogeneous virtualization management method in a cloud computing environment, as shown in fig. 1, including the following specific steps:
step S101, dividing all resource objects into one or more management domains according to the management characteristics of the resource objects in the cloud computing management platform.
Wherein resource objects in any one management domain have the same management characteristics.
Step S102, acquiring the ability description information of each management domain management resource object.
The capability description information for managing resource objects includes but is not limited to:
a set of Hypervisor (middleware layer) resources supported by the administrative domain, a set of Guest OS (virtual machine operating system) resources supported by the administrative domain, an operation supported by the administrative domain, and a set of functions supported by the administrative domain.
The Hypervisor is an intermediate software layer running between the physical server and the operating system, and may allow multiple operating systems and applications to share a set of basic physical hardware, so that the Hypervisor may also be regarded as a meta operating system in a Virtual environment, and the Hypervisor may coordinate to access all physical devices and Virtual machines on the server, also called Virtual Machine monitors (Virtual Machine monitors). Hypervisor is the core of all virtualization technologies. The ability to support multi-workload load migration without interruption is a basic function of hypervisors. When the server starts and executes the Hypervisor, it allocates appropriate amounts of memory, CPU (Central Processing Unit), network and disk to each virtual machine, and loads the guest operating systems of all the virtual machines.
The Guest OS is an operating system running on a VM (Virtual Machine). For example, Vmware (WeiRui) is installed on a computer with Windows NT installed, HOST refers to the computer with Windows NT installed, and its HOST's OS is Windows NT. Linux is running on the VM, and the Linux is Guest OS.
For example: in a heterogeneous cloud computing environment, resource objects include: an Intel type physical host, an AMD type physical host, a KVM type virtual host, and an XEN type virtual machine; different resource objects respectively provide different computing capabilities, while a user does not care about the type of a specific resource object and only care about whether an Intel type physical host and an AMD type physical host can both provide virtualization support, a management domain divides the resource objects providing virtualization functions into a virtualization type management domain, and the management domain provides computing virtualization capabilities to form a management domain with virtualization functions.
Step S103, acquiring the capability description information of all the management domains through the handshaking between any management domain and other management domains.
Specifically, step S103 includes:
any management domain handshakes with other management domains by issuing the capability description information of the management resource object to other management domains, and any management domain analyzes the capability description information of the management resource object issued by other management domains to acquire the capability description information of all the management domains.
For example: the management domain can issue own management domain capability, other management domains can explain the issued management domain capability, other management domain capabilities can be introduced, and all the management domain capabilities capable of completing the task can be found through a handshake process.
The handshaking of the administrative domain with other administrative domains includes: obtaining types of other management domains, obtaining IDs (unique codes) of other management domains, obtaining types of resource objects in other management domains, and obtaining IDs of resource objects in other management domains. When the management domain introduces other management domain capabilities, a Uniform Resource Identifier (URI) of the Resource is generated by the management domain instance and stored by the upper service system, and when the Resource is operated again, the URI information needs to be transferred to the domain instance.
And step S104, decomposing the cloud computing task into a plurality of subtasks, and respectively sending the subtasks to the management domains matched with the capability description information corresponding to the subtasks according to the preset mapping relation between the subtasks and the capability description information.
For example: the creation process of the virtual object comprises the following steps: when a user applies for a Virtual Machine with NUMA (non-Uniform Memory Access architecture) capability, if only a KVM (Kernel-based Virtual Machine) management domain in a management domain has NUMA capability, the creation task is allocated to the KVM management domain, and in the Virtual Machine creation process, a cloud host mounted with the same storage is automatically found, and then the host mounted with the same storage forms a management domain, so that the Virtual Machine scheduling is realized in the host management domain mounted with the same storage capability.
In a cloud computing environment, the state of resource objects within an administrative domain are constantly changing, and other administrative domains may need to take care of these state changes and make adjustments accordingly. Therefore, it is necessary to generate a message for each resource change in the management domain to be sent to other management domains, similar to the handshake procedure between the management domains.
According to the remote heterogeneous virtualization management method in the cloud computing environment, resources in different types of data centers and respective advantages of the management domains are uniformly managed through the management domains; the management of a remote heterogeneous virtualization management system in a cloud computing environment is simplified, the constraint conditions of cloud computing system management are reduced, and decoupling is realized between management domains; through the coordination of resources among management domains, the domains are easier to cooperate, and the characteristics of the whole system are exerted.
A second embodiment of the present invention provides a remote heterogeneous virtualization management method in a cloud computing environment, as shown in fig. 2, including the following specific steps:
step S101, dividing all resource objects into one or more management domains according to the management characteristics of the resource objects in the cloud computing management platform.
Wherein resource objects in any one management domain have the same management characteristics.
Mapping a resource object in a cloud computing management platform into a logic object based on a Common Information Model (CIM);
logical objects include, but are not limited to: physical hosts, virtual hosts, storage systems, storage pools, storage objects, switches, routers, distributed virtual switches, virtual routers, virtual networks, and protocol IP pools interconnected between networks.
For example: and performing layered abstraction aiming at different types of heterogeneous resources, for example, a KVM virtual machine, a Xen virtual machine abstracts into a virtual machine, the virtual machine and a physical machine further abstract into computing equipment, and a common part is extracted and abstracted into a logic resource and is uniformly managed in a management domain range.
Step S102, acquiring the ability description information of each management domain management resource object.
The capability description information for managing resource objects includes but is not limited to:
a set of Hypervisor (middleware layer) resources supported by the administrative domain, a set of Guest OS (virtual machine operating system) resources supported by the administrative domain, an operation supported by the administrative domain, and a set of functions supported by the administrative domain.
The Hypervisor is an intermediate software layer running between the physical server and the operating system, and may allow multiple operating systems and applications to share a set of basic physical hardware, so that the Hypervisor may also be regarded as a meta operating system in a Virtual environment, and the Hypervisor may coordinate to access all physical devices and Virtual machines on the server, also called Virtual Machine monitors (Virtual Machine monitors). Hypervisor is the core of all virtualization technologies. The ability to support multi-workload load migration without interruption is a basic function of hypervisors. When the server starts and executes the Hypervisor, it allocates appropriate amounts of memory, CPU (Central Processing Unit), network and disk to each virtual machine, and loads the guest operating systems of all the virtual machines.
The Guest OS is an operating system running on a VM (Virtual Machine). For example, Vmware (WeiRui) is installed on a computer with Windows NT installed, HOST refers to the computer with Windows NT installed, and its HOST's OS is Windows NT. Linux is running on the VM, and the Linux is Guest OS.
For example: in a heterogeneous cloud computing environment, resource objects include: an Intel type physical host, an AMD type physical host, a KVM type virtual host, and an XEN type virtual machine; different resource objects respectively provide different computing capabilities, while a user does not care about the type of a specific resource object and only care about whether an Intel type physical host and an AMD type physical host can both provide virtualization support, a management domain divides the resource objects providing virtualization functions into a virtualization type management domain, and the management domain provides computing virtualization capabilities to form a management domain with virtualization functions.
Step S103, acquiring the capability description information of all the management domains through the handshaking between any management domain and other management domains.
Specifically, step S103 includes:
any management domain handshakes with other management domains by issuing the capability description information of the management resource object to other management domains, and any management domain analyzes the capability description information of the management resource object issued by other management domains to acquire the capability description information of all the management domains.
For example: the management domain can issue own management domain capability, other management domains can explain the issued management domain capability, other management domain capabilities can be introduced, and all the management domain capabilities capable of completing the task can be found through a handshake process.
The handshaking of the administrative domain with other administrative domains includes: obtaining types of other management domains, obtaining IDs (unique codes) of other management domains, obtaining types of resource objects in other management domains, and obtaining IDs of resource objects in other management domains. When the management domain introduces other management domain capabilities, a Uniform Resource Identifier (URI) of the Resource is generated by the management domain instance and stored by the upper service system, and when the Resource is operated again, the URI information needs to be transferred to the domain instance.
Optionally, step S103 further includes:
and providing the capability description information of each management domain for the user, and processing the cloud computing task set by the user through the management domain selected by the user.
Through abstraction of the management domain layer, a user only needs to pay attention to the management domain, and specific details of a bottom layer virtualization platform do not need to be considered. To realize this feature, the upper layer service logic of the user should follow the following flow when processing:
1) issuing the management domain capability;
2) management domain capability introduction;
3) managing interactions between domains;
4) organizing basic information such as URI of resources;
5) resource control logic abstraction.
And step S104, decomposing the cloud computing task into a plurality of subtasks, and respectively sending the subtasks to the management domains matched with the capability description information corresponding to the subtasks according to the preset mapping relation between the subtasks and the capability description information.
For example: the creation process of the virtual object comprises the following steps: when a user applies for a Virtual Machine with NUMA (non-Uniform Memory Access architecture) capability, if only a KVM (Kernel-based Virtual Machine) management domain in a management domain has NUMA capability, the creation task is allocated to the KVM management domain, and in the Virtual Machine creation process, a cloud host mounted with the same storage is automatically found, and then the host mounted with the same storage forms a management domain, so that the Virtual Machine scheduling is realized in the host management domain mounted with the same storage capability.
In a cloud computing environment, the state of resource objects within an administrative domain are constantly changing, and other administrative domains may need to take care of these state changes and make adjustments accordingly. Therefore, it is necessary to generate a message for each resource change in the management domain to be sent to other management domains, similar to the handshake procedure between the management domains.
According to the remote heterogeneous virtualization management method in the cloud computing environment, resources in the domains are managed uniformly through the management domains, and the advantages of different types of data centers and different management domains are exerted; the management of a remote heterogeneous virtualization management system in a cloud computing environment is simplified, the constraint conditions of cloud computing system management are reduced, and decoupling is realized between management domains; through the coordination of resources among management domains, the domains are easier to cooperate, and the characteristics of the whole system are exerted.
