IOMMU seems to stop working with Dell r730 with PERC h730 mini in HBA mode. I'm not using efi (tried everything findable on the net and was not working). So now I'm in bios mode using Grub. There is an option in the r730 that is x2apic, which is enabled (kinda optimized enabled thing) and then...

Hi, i have the same problem. Did you find a solution ?

@avw I tried your solution. now its saying " cannot prepare PCI pass-through, IOMMU not present" this is my cat /proc/cmdline: BOOT_IMAGE=/boot/vmlinuz-5.13.19-2-pve root=/dev/mapper/pve-root ro quiet intel_iommu=on

I think it would work if there was a way to pass-through the host PCie bus, but it is only possible if the host CPU has an IOMMU that is only present on AMD-V or Intel-VT (?) I'm not sure, but that's my explanation from what I've read on the internet ... I'm trying to get ConBeeII working on a...

So i am trying to load pfSense on a VM and do a PCI passthrough for the nic. I am on 7.x i followed these steps to enable Dells version of IOMMU https://www.dell.com/support/kbdoc/en-us/000144029/enabling-sr-iov-technology-on-dell-poweredge-servers then followed...

This morning I updated my PVE-server from 7.0 to 7.1, using the enterprise-repository. After installing all updates I rebooted the server and it was extremely slow and the containers didn't even start (or at least not within 5 minutes). In the logs I found some entries about null pointer...

Hi guys, Actually I'm trying to follow the passthrough tutorial to use directly my graphic card on Windows VM under proxmox. When I try this command dmesg | grep -e DMAR -e IOMMU, but nothing appear. In the dmesg log I've a lot of error and want to fix then first. [66532.882862] DMAR: [DMA...

The definitive test whether IOMMU is working and passthrough is possible is by listing the groups using something like for d in /sys/kernel/iommu_groups/*/devices/*; do n=${d#*/iommu_groups/*}; n=${n%%/*}; printf 'IOMMU group %s ' "$n"; lspci -nnks "${d##*/}"; done. This will also tell us which...
