带有XenDesktop 7.6和网格K2的XenServer 6.2

您是否在自己的服务器版本上安装了相应的NVIDIA驱动程序？
就资源使用情况而言，nvidia smi.exe在该VM上报告的是什么？



以下为原文

Did you install the corresponding NVIDIA driver on your to match the server version? What does nvidia_smi.exe report on that VM as far as resource usage goes?

这是否意味着您在选择passthrough选项时遇到问题？
或者这是否意味着每当您连接GPU（passthrough或vGPU）时都会遇到问题
你在哪里遇到这个问题？
在XenCenter控制台中或通过ICA连接？



以下为原文



Does this mean that you have problems when you select the passthrough option?

Or does it mean that you have a problem whenever you attach a GPU (passthrough or vGPU)

Where do you get the problem? In the XenCenter console or via an ICA connection?

如果我在VM属性中选择vGPU（K200到K280Q），则VM变慢（慢速win7安装，慢速启动，......），如果VM GPU设置为none或直通，则一切运行顺利。
希望现在很清楚。
我正在使用XenCenter控制台进行检查。
它在我看来问题是在XenServer方面，有些东西正在使用CPU，我现在不知道是什么。
我将从USB重新安装XenServer到SSD，看看是否有任何变化......
谢谢



以下为原文

If I select vGPU (K200 to K280Q) in VM properties then VM becomes slow (slow win7 install, slow boot,...) and if VM GPU is set to none or passthrough everything is running smoothly.
Hope it is clear now.
I am checking this with XenCenter console. It looks to me that problem is in XenServer side, something is using CPU and I dont now what. I am going to reinstall XenServer from USB to SSD and will see if anything changes...

Thanks

None


以下为原文

I had no luck. Everything works the same. Please check CPU usage when VM (with K280Q) is booted and no app is running.

Bios is up to date.
