The Cisco IOS& XRv 9000 Router implements the feature set of Cisco IOS XR Software. Running on virtualized general x86 compute platforms, it complements existing physical Cisco& router platforms that rely on Cisco IOS XR Software, such as Cisco Network Convergence System routers, Cisco ASR 9000 Series Routers, and Cisco Carrier Routing System (CRS) platforms. Now, service providers can enhance their operational excellence and offerings based on physical routers - and move them easily to a virtual form factor. The Cisco IOS XRv 9000 Router (Figure 1) offers greater agility, improved network efficiency, lower capital and operational expenditures, and the ability to efficiently scale network capacity up and down, based on demand.
●End-to-end solution with network functions virtualization (NFV) infrastructure, virtual network functions, and service orchestration and management
●Based on the extremely resilient, stable, and feature-rich Cisco IOS-XR Software, with the same northbound and management features as Cisco IOS XR Software, which helps ensure smooth integration with existing OSS and business support systems (BSS)
●High-performance data plane with service provider edge features, such as Quality of Service, access control list, and NetFlow
●Architecture that separates the control plane and data plane, which allows for scaling up and down with multicore, multisocket, and multiserver systems
The Cisco IOS XRv 9000 Router can be deployed in the following two ways:
●For control plane functionality, such as a virtual route reflector
●As a high-performance data plane, based on an X86-optimized code base, developed specifically for Cisco nPower network processor units (NPUs), and the Intel& Data Plane Development Kit (DPDK)
Figure 1.& Cisco IOS XRv 9000 Router
Cisco IOS XRv 9000 Router as a control plane: The Cisco IOS XR Software is an industry-leading, carrier-class operating system supporting highly successful edge and core router platforms from Cisco. This modular OS provides a very high level of availability (Figure 2), and its multiprocess and multithread architecture enhances scale and performance by taking advantage of modern multisocket and multicore processors.
Figure 2.& Cisco IOS XR Software High Availability
Cisco IOS XRv 9000 Router as a data plane (virtual forwarder): The virtual forwarder uses the feature and forwarding code developed for Cisco NPU-based physical platforms. However, it is optimized specifically for NFV-based general-purpose CPU environments. It uses Intel Streaming SIMD Extensions 2 (SSE2) and Advanced Vector Extensions (AVX) instructions for improved software-based classification. Memory access is asynchronous for parallel feature processing, and data structures are optimized for best utilization of the cache. In addition, batched packet delivery and processing and high-speed load balancing across the feature execution process help provide a very-high-performance data plane, with the features service providers require.
Table 1.Deployment model and Benefits
A service provider needs to provide Layer 3 provider edge functionality at a location which has low throughput. They already have their service and offerings based on physical Cisco ASR 9000 Series devices and want to offer the same services at the low-throughput location
●Consistent architecture with widely used ASR 9000 Series platforms
●Rich set of networking experiences based on Cisco IOS XR Software
●Reduced capital expenditures (CapEx) and operating expenses (OpEx) realized by using consumption-based models
Traditionally a service provider deployed physical routing devices as route reflectors. A route reflector application makes intensive use of the control plane and is low on data plane usage. This leads to suboptimal usage of the capacity provided by the physical router
●Convergence of many route reflectors into a few virtual route reflectors using Cisco IOS- XRv 9000 Router
●Significant reduction of the physical footprint, power, cooling, and cabling overhead associated with maintaining physical route reflector systems
The Cisco IOS XRv 9000 Router offers a flexible licensing scheme, with multiple tiers to choose from, such as Scale, Throughput, Deployment Model, and Term. The licensing structure allows service providers to pay for what they consume. Licenses are activated through Cisco Smart Software Licensing. Further details about Cisco Smart Software Licensing are available at: .

iosxrv-k9-demo-5.1.1&&和iosxrv-k9-demo-5.2.0 都试过了，第1次导入可以正常登录。
之后电脑重启，不管是暂停设备还是关闭设备。总之进不去。CRT提示一直停留在attaching console,wait ...
网络收集解决方法：
1.退出VM时，不点“关闭设备”，只是“暂停”
2.重置PIPE工具，edit-reset .
=======================================
ps,我每次点击VM时，是用管理员运行的VM。（因之前提示过内存不可用，必须用管理员运行才可以）。
今天我发布这条帖的时候，发现一个现象了，不用管理员运行VM。直接点击VM,打开XRV虚拟机，竟然可以正常运行XRV了，也可以登录了。（静待观察一段时间，特发布此帖，告诉有一样困惑的人。这个问题搞了我2个星期了，唉......）
如有最新变化，我会更新此帖！！！

补充说明：昨天又有新进展，其实只要你点击右键用管理员帐号运行CRT，再运行vrx-IOS也是可以的。
我目前在解决：XRV-IOS和web-iou对接网卡，不能启用协议问题（OSPF可以，ISIS不行）。有谁可以实现，麻烦告诉我下，谢谢！

确实，我在VM中运行ASA，通过NPTP映射console，VM一开始用管理员身份启动，NPTP一直是Attaching。网上搜到楼主的解决方法，十分感谢！
