The array card is not visible in the pass through list

[你的益达]

Hello, I'm from China and I'm using translation software to ask questions. I'm not good at English. If the translation is not accurate, please forgive me. I will try my best to make the translation correct.

My question is:

After I added a PCI-E HP 10G network card, the LSI2308 array card I normally supported suddenly disappeared from the pass through list. I don't know how to deal with it. I checked the messages file log under/var/log and found that my array card appeared in the third second of system startup.

I don't know whether the log I checked is correct, so I would like to ask what files I should submit to the forum for support.

Hi,

No problem, the translation seems good to me.

Regarding your problem: have you looked at the pci passthrough wiki entry? Especially the iommu section?

Yes, I have turned on this function and can recognize it before I add the network card

我想我已经知道问题所在了 是因为我在GURB添加了pci=assign-busses 参数的原因，当我删除这个参数后，我重新启动计算机 在这之后我的所有PCI硬件设备直通都正常了。但是我还是不敢完全确定是不是这个原因，但是可以使用了 不必再追踪问题了。

I think I already know the problem is because I added the pci=assign-busses parameter in GURB. When I delete this parameter, I restart the computer. After that, all my PCI hardware devices are normal. But I'm still not sure whether it is the reason, but it can be used without tracing the problem.

That could definitely be the problem.

But if your setup works without passing this kernel parameter that is good.
