RobertWicked Posted December 27, 2021 Share Posted December 27, 2021 Hello! Long time user here, and i'm currently working on migrating from a dell T5500 to a hp z840. Things went downhill from what I thought should be a fairly easy switch. I have some VM's that utilize the pci passthrough and i went to configure them, but the IOMMU groups did not exist. I checked the cpu and it supports vt-d. I checked bios settings and it shows vt-d as enabled. I did attempt to search around to find some info on here, but those items seemed to be what fixed most users issues. I migrated back, and i'm putting together a quick test build so I can get some logs. If anyone can offer some advice, I'd appreciate it! Thank you! Quote Link to comment

RobertWicked Posted December 27, 2021 Author Share Posted December 27, 2021 it is dual Intel® Xeon® Processor E5-2680 v3. I verified it's the options under usb security (why they put it there no one knows) and enabled vt-x and vt-d. I also made sure the bios is completely up to date. Quote Link to comment

I just got home to throw a trail up on the box real quick so I can pull logs and diagnostics... but now i don't need to. I totally missed the box was setup for legacy boot and I didn't notice! Switched it to uefi and it's working!!!! Thanks for catching that good sir! 1 Quote Link to comment
