Xendesktop未能获得许可证

您应该检查从guest虚拟机到许可证服务器的所有防火墙。
“http：// licenseserver：7070”正确答案应为“404 Not Found”（许可证流程使用REST API POST“http：// licenseserver：7070 / request”）。
#curl -v http：// licenseserver：7070
*重建URL到：http：// licenseserver：7070 /
*尝试许可证服务器......
* TCP_NODELAY设置
*连接到licenseserver（licenseserver）端口7070（＃0）
> GET / HTTP / 1.1
>主持人：licenseserver：7070
> User-Agent：curl / 7.59.0

You should check all firewalls from guest to license server. The "http://licenseserver:7070" correct answer should be "404 Not Found" (license process uses REST API POST "http://licenseserver:7070/request").

感谢您的额外信息。
我已经尝试禁用客户端和许可证服务器上的本地防火墙，我已将它们移动到同一子网上，以避免交叉子网防火墙全部没有区别。
我已经测试了所有的URL，它们都响应客户端的响应，表明许可证服务器确实在工作。
我还使用currports来检查7070正在服务器上监听。
许可证服务器上是否有某个日志可能显示与客户端的通信以及为什么它没有获得许可证？



以下为原文

Thanks for the extra info. I have tried disabling the local firewalls on the client and license server and I have moved them to be on the same subnet to avoid an cross subnet firewall all with no difference.

I have tested all the URLs and they all respond with responses to the client suggesting the license server is indeed working. I have also used currports to check 7070 is listening on the server.

Is there a log somewhere on the license server which might show the communication with the client and why it isn't getting a license?

/var/opt/flexnetls/nvidia/logs/access*request.log中的许可证请求类似于（检查其他日志）：
guest_ip  -   -  [28 / Jun / 2018：10：17：08 +0000]“POST / request HTTP / 1.1”200 889 271



以下为原文

License request in /var/opt/flexnetls/nvidia/logs/access*request.log is something like (check other logs too):

guest_ip - - [28/Jun/2018:10:17:08 +0000] "POST /request HTTP/1.1" 200 889  271

对不起 - 我在服务器或客户端都找不到该目录？
如果有所不同，我将Windows用于客户端和服务器。
我只能找到一堆tomcat，Catalina，host-manager和localhost日志文件。
没有访问日志？
我也尝试过配置一组新的VDI主机，但问题仍然存在，尽管它在尝试获取和失败之间不断循环时会尝试很多。
我在另一篇文章中发现，如果您在成像前获得原始图像的许可证可能会出现问题。
您是否了解任何问题，是否有从图像中删除许可证的简洁方法？



以下为原文

Sorry - I can't find that dir on either server or client? I am using Windows for both client and server if that makes a difference. I can only find a bunch of tomcat, Catalina, host-manager, and localhost log files. No access logs?

I have also tried provisioning a new set of VDI hosts but the issue persists although it does try a lot to get a license constantly cycling between acquiring and failing.

I found in another post there can be problems if you acquire a license in the original image before imaging. Are you aware of any issues and is there a clean way of removing the license from the image?

感谢您提供新信息。
我已经应用了该注册表项。
我现在的问题是我根本无法获得许可证。
它只是报告无法在弹出通知中获取许可证。
然后循环获取许可证......



以下为原文

Thanks for the new info. I have already applied that registry key though. My issue now is that I am not able to acquire a license at all. It just reports Failed to acquire license in a popup notification. Then cycles around to acquiring license...

好的 - 我发现Windows服务器上的日志文件位于C： Windows  ServiceProfiles  NetworkService  flexnetls  nvidia  logs，从中我发现有错误 -
16：37：26,626 WARN无法处理功能GRID-Virtual-PC 2.0 count = 1的请求。

以下为原文

OK - I found the log files on a Windows server are located at C:WindowsServiceProfilesNetworkServiceflexnetlsnvidialogs and from this I found that there is an error -

This is repeated over and over.

嗨马特曼，
从消息HOST_ID不匹配我首先检查你的licserver。
似乎有一些变化（例如MAC或IP），因此lic文件不再有效。
问候
西蒙



以下为原文

Hi Matman,

from the message HOST_ID mismatch I would first of all check your licserver. Seems there is something changed (MAC or IP for example) so that the lic file is not valid any more.

Regards

Simon

谢谢西蒙。
这就是我的想法。
发现我必须将MAC地址设置为静态，因为许可证服务器已实时迁移到新主机并收到新的MAC地址。
使用许可证上使用的设置将其设置为静态，并且所有设置都恢复正常。



以下为原文

Thanks Simon. That's what I was figuring. Found that I had to set the MAC address to static as the license server had live migrated to a new host and received a new MAC address.

Set it to static with the one used on the license and all is back to normal.
