This document defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, this specifies objects for managing virtual machines controlled by a hypervisor (a.k.a. virtual machine monitor). A hypervisor controls multiple virtual machines on a single physical machine by allocating resources to each virtual machine using virtualization technologies. Therefore, this MIB module contains information on virtual machines and their resources controlled by a hypervisor as well as information about a hypervisor's hardware and software.
本文档定义了管理信息库（MIB）的一部分，用于Internet社区中的网络管理协议。特别是，它指定了用于管理由虚拟机监控程序（又称虚拟机监视器）控制的虚拟机的对象。虚拟机监控程序通过使用虚拟化技术为每个虚拟机分配资源来控制单个物理机上的多个虚拟机。因此，此MIB模块包含有关虚拟机及其由虚拟机监控程序控制的资源的信息，以及有关虚拟机监控程序的硬件和软件的信息。
The design of this MIB module has been derived from product-specific MIB modules -- namely, a MIB module for managing guests of the Xen hypervisor [Xen], a MIB module for managing virtual machines controlled by the VMware hypervisor [VMware], and a MIB module using the libvirt programming interface [libvirt] to access different hypervisors. However, this MIB module attempts to generalize the managed objects to support other implementations of hypervisors.
此MIB模块的设计源自特定于产品的MIB模块，即用于管理Xen虚拟机监控程序[Xen]的来宾的MIB模块、用于管理由VMware虚拟机监控程序[VMware]控制的虚拟机的MIB模块，以及使用libvirt编程接口[libvirt]访问不同虚拟机监控程序的MIB模块。但是，此MIB模块试图概括托管对象，以支持管理程序的其他实现。
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].
本文件中的关键词“必须”、“不得”、“要求”、“应”、“不应”、“应”、“不应”、“建议”、“可”和“可选”应按照RFC 2119[RFC2119]中所述进行解释。

Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].
托管对象通过虚拟信息存储（称为管理信息库或MIB）进行访问。MIB对象通常通过简单网络管理协议（SNMP）进行访问。MIB中的对象是使用管理信息结构（SMI）中定义的机制定义的。本备忘录规定了符合SMIv2的MIB模块，如STD 58、RFC 2578[RFC2578]、STD 58、RFC 2579[RFC2579]和STD 58、RFC 2580[RFC2580]所述。
This document defines a portion of MIB for the management of virtual machines controlled by a hypervisor. This MIB module consists of the managed objects related to system and software information of a hypervisor, the list of virtual machines controlled by the hypervisor, and information of virtual resources allocated to virtual machines by the hypervisor. This document specifies four specific types of virtual resources that are common to many hypervisor implementations: processors (CPUs), memory, network interfaces (NICs), and storage devices. These managed objects are independent of the families of hypervisors or operating systems running on virtual machines.
本文档定义了MIB的一部分，用于管理由虚拟机监控程序控制的虚拟机。此MIB模块由与虚拟机监控程序的系统和软件信息相关的托管对象、由虚拟机监控程序控制的虚拟机列表以及虚拟机监控程序分配给虚拟机的虚拟资源信息组成。本文档指定了许多虚拟机监控程序实现共有的四种特定类型的虚拟资源：处理器（CPU）、内存、网络接口（NIC）和存储设备。这些托管对象独立于虚拟机上运行的虚拟机监控程序或操作系统系列。

Figure 1: An Example of a Virtualization Environment
图1：虚拟化环境的示例
On the common implementations of hypervisors, a hypervisor allocates virtual resources from physical resources: virtual CPUs, virtual memory, virtual storage devices, and virtual network interfaces to virtual machines as shown in Figure 1. Since the virtual resources allocated to virtual machines are managed by the hypervisor, the MIB objects are managed at the hypervisor. In case that the objects are accessed through the SNMP, an SNMP agent is launched at the hypervisor to provide access to the objects.
在虚拟机监控程序的常见实现中，虚拟机监控程序从物理资源（虚拟CPU、虚拟内存、虚拟存储设备和虚拟网络接口）向虚拟机分配虚拟资源，如图1所示。由于分配给虚拟机的虚拟资源由虚拟机监控程序管理，因此MIB对象在虚拟机监控程序中管理。如果通过SNMP访问对象，则会在虚拟机监控程序中启动SNMP代理以提供对对象的访问。
The objects are managed from the viewpoint of the operators of hypervisors, but not the operators of virtual machines; that is, the objects do not take into account the actual resource utilization on each virtual machine but rather the resource allocation from the physical resources. For example, vmNetworkIfIndex indicates the virtual interface associated with an interface of a virtual machine at the hypervisor, and consequently, the 'in' and 'out' directions denote 'from a virtual machine to the hypervisor' and 'from the hypervisor to a virtual machine', respectively. Moreover, vmStorageAllocatedSize denotes the size allocated by the hypervisor, but not the size actually used by the operating system on the virtual machine. This means that vmStorageDefinedSize and vmStorageAllocatedSize do not take different values when the vmStorageSourceType is 'block' or 'raw'.
从虚拟机监控程序操作员的角度管理对象，而不是从虚拟机操作员的角度管理对象；也就是说，对象不考虑每个虚拟机上的实际资源利用率，而是考虑物理资源的资源分配。例如，VMNetworkiIndex表示与虚拟机监控程序中的虚拟机接口关联的虚拟接口，因此，“入”和“出”方向分别表示“从虚拟机到虚拟机监控程序”和“从虚拟机监控程序到虚拟机”。此外，vmStorageAllocatedSize表示虚拟机监控程序分配的大小，而不是虚拟机上操作系统实际使用的大小。这意味着当vmStorageSourceType为“block”或“raw”时，vmStorageDefinedSize和vmStorageAllocatedSize不会采用不同的值。
The objectives of this document are the following: 1) this document defines the MIB objects common to many hypervisors for the management of virtual machines controlled by a hypervisor, and 2) this document clarifies the relationship with other MIB modules for managing host computers and network devices.
本文档的目标如下：1）本文档定义了许多虚拟机监控程序共有的MIB对象，用于管理由虚拟机监控程序控制的虚拟机；2）本文档澄清了与其他MIB模块的关系，用于管理主机和网络设备。
The MIB module is organized into a group of scalars and tables. The scalars below 'vmHypervisor' provide basic information about the hypervisor. The 'vmTable' lists the virtual machines (guests) that are known to the hypervisor. The 'vmCpuTable' provides the mapping table of virtual CPUs to virtual machines, including CPU time used by each virtual CPU. The 'vmCpuAffinityTable' provides the affinity of each virtual CPU to a physical CPU. The 'vmStorageTable' provides the list of virtual storage devices and their mapping to virtual machines. In case that an entry in the 'vmStorageTable' has a corresponding parent physical storage device managed in 'vmStorageTable' of HOST-RESOURCES-MIB [RFC2790], the entry contains a pointer 'vmStorageParent' to the physical storage device. The 'vmNetworkTable' provides the list of virtual network interfaces and their mapping to virtual machines. Each entry in the 'vmNetworkTable' also provides a pointer 'vmNetworkIfIndex' to the corresponding entry in the 'ifTable' of IF-MIB [RFC2863]. In case that an entry in the 'vmNetworkTable' has a corresponding parent physical network interface managed in the 'ifTable' of IF-MIB, the entry contains a pointer 'vmNetworkParent' to the physical network interface.
MIB模块被组织成一组标量和表。“vmHypervisor”下面的标量提供了有关虚拟机监控程序的基本信息。“vmTable”列出了虚拟机监控程序已知的虚拟机（来宾）。“vmCpuTable”提供虚拟CPU到虚拟机的映射表，包括每个虚拟CPU使用的CPU时间。“vmCpuAffinityTable”提供每个虚拟CPU与物理CPU的关联。“VMStorage Table”提供虚拟存储设备及其到虚拟机的映射的列表。如果“vmStorageTable”中的条目具有在HOST-RESOURCES-MIB[RFC2790]的“vmStorageTable”中管理的相应父物理存储设备，则该条目包含指向该物理存储设备的指针“vmStorageParent”。“vmNetworkTable”提供虚拟网络接口及其到虚拟机的映射列表。“vmNetworkTable”中的每个条目还提供指向IF-MIB[RFC2863]的“ifTable”中相应条目的指针“VMNetworkiIndex”。如果“vmNetworkTable”中的条目具有在IF-MIB的“ifTable”中管理的相应父物理网络接口，则该条目包含指向该物理网络接口的指针“vmNetworkParent”。

Figure 2: State Transition of a Virtual Machine
图2：虚拟机的状态转换
The 'vmAdminState' and 'vmOperState' textual conventions define an administrative state and an operational state model for virtual machines. Events causing transitions between major operational states will cause the generation of notifications. Per virtual machine (per-VM) notifications (vmRunning, vmShutdown, vmPaused, vmSuspended, vmCrashed, vmDeleted) are generated if vmPerVMNotificationsEnabled is true(1). Bulk notifications (vmBulkRunning, vmBulkShutdown, vmBulkPaused, vmBulkSuspended, vmBulkCrashed, vmBulkDeleted) are generated if vmBulkNotificationsEnabled is true(1). The overview of the transition of 'vmOperState' by the write access to 'vmAdminState' and the notifications generated by the operational state changes are illustrated in Figure 2. The detailed state transition is summarized in Appendix A. Note that the notifications shown in this figure are per-VM notifications. In the case of Bulk notifications, the prefix 'vm' is replaced with 'vmBulk'.
“vmAdminState”和“VMOperate”文本约定定义了虚拟机的管理状态和操作状态模型。导致主要操作状态之间转换的事件将导致生成通知。如果vmPerVMNotificationsEnabled为true（1），则会生成每虚拟机（每虚拟机）通知（vmRunning、vmShutdown、vmPaused、vmSuspended、VMCrash、vmDeleted）。如果vmBulkNotificationsEnabled为true（1），则会生成批量通知（vmBulkRunning、vmBulkShutdown、vmBulkPaused、vmBulkSuspended、VMBulkCrash、vmBulkDeleted）。图2展示了通过对“vmAdminState”的写访问权对“vmOperState”的转换以及操作状态更改生成的通知的概述。详细的状态转换总结在附录A中。请注意，此图中显示的通知是每个VM通知。对于批量通知，前缀“vm”将替换为“vmBulk”。
The bulk notification mechanism is designed to reduce the number of notifications that are trapped by an SNMP manager. This is because the number of virtual machines managed by a bunch of hypervisors in a data center possibly becomes several thousands or more, and consequently, many notifications could be trapped if these virtual machines frequently change their administrative state. The per-VM notifications carry more detailed information, but the scalability is a problem. The notification filtering mechanism described in Section 6 of RFC 3413 [RFC3413] is used by the management applications to control the notifications.
批量通知机制旨在减少SNMP管理器捕获的通知数量。这是因为一个数据中心中由一组虚拟机监控程序管理的虚拟机数量可能会增加到数千或更多，因此，如果这些虚拟机频繁更改其管理状态，可能会捕获许多通知。每VM通知包含更详细的信息，但可伸缩性是一个问题。管理应用程序使用RFC 3413[RFC3413]第6节中描述的通知过滤机制来控制通知。
The HOST-RESOURCES-MIB [RFC2790] defines the MIB objects for managing host systems. On systems implementing the HOST-RESOURCES-MIB, the objects of HOST-RESOURCES-MIB indicate resources of a hypervisor. Some objects of HOST-RESOURCES-MIB are used to indicate physical resources through indexes. On systems implementing HOST-RESOURCES-MIB, the 'vmCpuPhysIndex' points to the processor's 'hrDeviceIndex' in the 'hrProcessorTable'. The 'vmStorageParent' also points to the storage device's 'hrStorageIndex' in the 'hrStorageTable'.
HOST-RESOURCES-MIB[RFC2790]定义了用于管理主机系统的MIB对象。在实现HOST-RESOURCES-MIB的系统上，HOST-RESOURCES-MIB的对象表示虚拟机监控程序的资源。HOST-RESOURCES-MIB的一些对象用于通过索引指示物理资源。在实现HOST-RESOURCES-MIB的系统上，“vmCpuPhysIndex”指向“hrProcessorTable”中处理器的“hrDeviceIndex”。“vmStorageParent”还指向“hrStorageTable”中存储设备的“hrStorageIndex”。
The IF-MIB [RFC2863] defines the MIB objects for managing network interfaces. Both physical and virtual network interfaces are required to be contained in the 'ifTable' of IF-MIB. The virtual network interfaces in the 'ifTable' of IF-MIB are pointed from the 'vmNetworkTable' defined in this document through a pointer 'vmNetworkIfIndex'. In case that an entry in the 'vmNetworkTable'
IF-MIB[RFC2863]定义了用于管理网络接口的MIB对象。物理和虚拟网络接口都需要包含在IF-MIB的“ifTable”中。IF-MIB的“ifTable”中的虚拟网络接口通过指针“VMNetworkiIndex”从本文档中定义的“vmNetworkTable”指向。如果“vmNetworkTable”中的条目
has a corresponding parent physical network interface managed in the 'ifTable' of IF-MIB, the entry contains a pointer 'vmNetworkParent' to the physical network interface.
如果在IF-MIB的“ifTable”中管理了相应的父物理网络接口，则该条目包含指向该物理网络接口的指针“vmNetworkParent”。
The objects related to virtual switches are not included in the MIB module defined in this document though virtual switches MAY be placed on a hypervisor. This is because the virtual network interfaces are the lowest abstraction of network resources allocated to a virtual machine. Instead of including the objects related to virtual switches, for example, IEEE8021-BRIDGE-MIB [IEEE8021-BRIDGE-MIB] and IEEE8021-Q-BRIDGE-MIB [IEEE8021-Q-BRIDGE-MIB] could be used.
与虚拟交换机相关的对象不包括在本文档中定义的MIB模块中，尽管虚拟交换机可以放置在虚拟机监控程序上。这是因为虚拟网络接口是分配给虚拟机的网络资源的最低抽象。例如，可以使用IEEE8021-BRIDGE-MIB[IEEE8021-BRIDGE-MIB]和IEEE8021-Q-BRIDGE-MIB[IEEE8021-Q-BRIDGE-MIB]，而不包括与虚拟交换机相关的对象。
The other objects related to virtual machines such as management IP addresses of a virtual machine are not included in this MIB module because this MIB module defines the objects common to general hypervisors, but they are specific to some hypervisors. They may be included in the entLogicalTable of ENTITY-MIB [RFC6933].
与虚拟机相关的其他对象（如虚拟机的管理IP地址）不包括在此MIB模块中，因为此MIB模块定义了通用虚拟机监控程序通用的对象，但它们特定于某些虚拟机监控程序。它们可能包含在ENTITY-MIB[RFC6933]的entLogicalTable中。
The SNMPv2-MIB [RFC3418] provides an object 'sysObjectID' that identifies the network management subsytem and an object 'sysUpTime' that reports the uptime of the network management portion of the system. The HOST-RESOURCES-MIB [RFC2790] provides an object 'hrSystemUptime' that reports the uptime of the host's operating system. To complement these objects, the new 'vmHvUpTime' object reports the time since the hypervisor was last re-initialized, and the new 'vmHvObjectID' provides an identification of the hypervisor software.
SNMPv2 MIB[RFC3418]提供一个对象“sysObjectID”，用于标识网络管理子系统，以及一个对象“sysUpTime”，用于报告系统网络管理部分的正常运行时间。HOST-RESOURCES-MIB[RFC2790]提供一个对象“hrSystemUptime”，用于报告主机操作系统的正常运行时间。为了补充这些对象，新的“vmHvUpTime”对象报告自虚拟机监控程序上次重新初始化以来的时间，新的“vmHvObjectID”提供虚拟机监控程序软件的标识。

The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
本文档中的MIB模块使用SMI编号注册表中记录的以下IANA分配的对象标识符值：
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
Descriptor OBJECT IDENTIFIER value

vmMIB { mib-2 236 }
ianaStorageMediaTypeMIB { mib-2 237 }
vmMIB { mib-2 236 }
ianaStorageMediaTypeMIB { mib-2 237 }
This MIB module is typically implemented on the hypervisor not inside a virtual machine. Virtual machines, possibly under other administrative domains, would not have access to this MIB as the SNMP service would typically operate in a separate management network.
此MIB模块通常在虚拟机内的虚拟机监控程序上实现。虚拟机（可能位于其他管理域下）将无法访问此MIB，因为SNMP服务通常在单独的管理网络中运行。
There are two objects defined in this MIB module, vmPerVMNotificationsEnabled and vmBulkNotificationsEnabled, that have a MAX-ACCESS clause of read-write. Enabling notifications can lead to a substantial number of notifications if many virtual machines change their state concurrently. Hence, such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on the management system. It is RECOMMENDED that these objects have access of read-only instead of read-write on deployments where SNMPv3 strong security (i.e., authentication and encryption) is not used.
此MIB模块中定义了两个对象，vmPerVMNotificationsEnabled和vmBulkNotificationsEnabled，它们具有读写的MAX-ACCESS子句。如果许多虚拟机同时更改其状态，启用通知可能会导致大量通知。因此，在某些网络环境中，此类对象可能被视为敏感或易受攻击。在没有适当保护的非安全环境中支持SET操作可能会对管理系统产生负面影响。在不使用SNMPv3强安全性（即身份验证和加密）的部署中，建议这些对象具有只读访问权限，而不是读写访问权限。
There are a number of managed objects in this MIB that may contain sensitive information. The objects in the vmHvSoftware and vmHvVersion list information about the hypervisor's software and version. Some may wish not to disclose to others which software they are running. Further, an inventory of the running software and versions may be helpful to an attacker who hopes to exploit software bugs in certain applications. Moreover, the objects in the vmTable, vmCpuTable, vmCpuAffinityTable, vmStorageTable, and vmNetworkTable list information about the virtual machines and their virtual resource allocation. Some may wish not to disclose to others how many and what virtual machines they are operating.
此MIB中有许多托管对象可能包含敏感信息。vmHvSoftware和vmHvVersion中的对象列出了有关虚拟机监控程序软件和版本的信息。有些人可能不希望向其他人透露他们正在运行的软件。此外，运行软件和版本的清单可能有助于攻击者利用某些应用程序中的软件漏洞进行攻击。此外，vmTable、vmCpuTable、vmCpuAffinityTable、vmStorageTable和vmNetworkTable中的对象列出了有关虚拟机及其虚拟资源分配的信息。有些人可能不希望向其他人透露他们操作的虚拟机数量和种类。
It is thus important to control even GET access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. Not all versions of SNMP provide features for such a secure environment.
因此，在通过SNMP通过网络发送这些对象时，控制甚至访问这些对象，甚至可能加密这些对象的值，这一点非常重要。并非所有版本的SNMP都为这种安全环境提供功能。
SNMPv1 by itself is not a secure environment. Even if the network itself is secure (for example by using IPsec), there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module.
SNMPv1本身不是一个安全的环境。即使网络本身是安全的（例如通过使用IPsec），也无法控制安全网络上的谁可以访问和获取/设置（读取/更改/创建/删除）此MIB模块中的对象。
It is recommended that the implementers consider using the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model [RFC3414] and the View-based Access Control Model [RFC3415] is recommended.
建议实施者考虑使用SNMPv3框架提供的安全特性。具体而言，建议使用基于用户的安全模型[RFC3414]和基于视图的访问控制模型[RFC3415]。
It is then a customer/user responsibility to ensure that the SNMP entity giving access to an instance of this MIB is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.
然后，客户/用户有责任确保授予对此MIB实例访问权限的SNMP实体被正确配置为仅授予那些确实拥有获取或设置（更改/创建/删除）对象的合法权限的主体（用户）对对象的访问权限。
