Hi,
I changed motherboard and CPU recently on my server and a lot broke. But finally, when I got proxmox to boot and got access to the web interface, I have to passthrough my PCIe devices again. The problem I am running into is that when following the guide PCI Passthrough, when I run;
dmesg | grep -e DMAR -e IOMMU
it returns that it is enabled. But when I run;
dmesg | grep 'remapping'
it returns that it isn't supported, so I run;
echo "options vfio_iommu_type1 allow_unsafe_interrupts=1" > /etc/modprobe.d/iommu_unsafe_interrupts.conf.
Everything is fine up until I run;
pvesh get /nodes/{nodename}/hardware/pci --pci-class-blacklist ""
I get the following output:
Everything is on the same iommugroup, and also has -1 as iommugroup which seems odd. I don't know what else could be wrong. In grub I have the following settings:
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"
GRUB_CMDLINE_LINUX=""
