Hello everyone,

 

I m using PowerEdge R740 server. My CPU is "Intel(R) Xeon(R) Gold 6240 CPU @ 2.60GHz"

 

My OS is Redhat 6.9

 

I want to vt-d check on my server. 

 

I activated it from bios but I cannot see any log related to vt-d in dmesg logs.

 

I m using this command for vt-d check -> dmesg | grep "IOMMU. * enabled"

 

Are there any check for vt-d ? 

 

After the bios enabled, Should I use this parameter? : intel_iommu=on

 

Please can u help me?

 

Thanks.
