Unable to pass two VF of Intel X550-T2 as PCIe to two VMs

Sandbo · Aug 6, 2019

I have set up SR-IOV with my platform running PVE 6, with AMD Athlon 200GE, Asrock X470ITX and an Intel X550-T2. The guests here are two ubuntu server. Other combination of VMs were tested and produced the same result. Q35 and OVMF are being used.

While SR-IOV works, if I assign 1 VF each to 2 VMs with checking the box PCI-E, the 1st VM can boot but then the second VM will should "Guest has not initialized video" and stays there.

The same won't happen if I assign the VF as PCI without checking the PCIe box.

Is there anything I have missed?

can you post your 'pveversion -v' and 'lspci' output, the vm configs and the iommu groupings ?

the assignment test has been done between any two VMs. As soon as I assign two PCI-E VFs over two VMs, the second one that boots later won't boot.

A similar experience is being shared by a redditor:

The PFs are
/sys/kernel/iommu_groups/44/devices/0000:60:00.0 >> NIC 1
/sys/kernel/iommu_groups/45/devices/0000:60:00.1 >> NIC 2

The VFs associated with NIC 1 are:
/sys/kernel/iommu_groups/75/devices/0000:60:02.0
/sys/kernel/iommu_groups/76/devices/0000:60:02.1
/sys/kernel/iommu_groups/77/devices/0000:60:02.2
/sys/kernel/iommu_groups/78/devices/0000:60:02.3

And the VFs associated with NIC 2 are:
/sys/kernel/iommu_groups/79/devices/0000:60:06.0
/sys/kernel/iommu_groups/80/devices/0000:60:06.1
/sys/kernel/iommu_groups/81/devices/0000:60:06.2
/sys/kernel/iommu_groups/82/devices/0000:60:06.3

The config for the VM is

Code:

bios: ovmf
boot: dcn
bootdisk: scsi0
cores: 4
cpu: host
efidisk0: local-zfs:vm-901-disk-1,size=128K
hostpci0: 60:06.0,pcie=1
hostpci1: 60:06.1
hostpci2: 60:06.2
hostpci3: 60:06.3
machine: q35
memory: 16384
name: test01
numa: 1
ostype: l26
sata0: local:iso/ubuntu-18.04.2-desktop-amd64.iso,media=cdrom,size=1904M
scsi0: local-zfs:vm-901-disk-0,cache=writeback,size=16G
scsihw: virtio-scsi-pci
smbios1: uuid=024b8ccd-bc78-4cbb-aaf4-a32c8652636c
sockets: 2
vga: virtio
vmgenid: 19fcf93d-01be-4c1e-8afc-7344ff95fc85

My problem is a little bit different thought. Only the first VF on each NIC can be set to PCIe mode. Unlike the original post, I can passthrough multiple VFs to a VM, but only the first one can be in PCIe mode. The other VFs simply does not work with `pcie=1` even if they are the only VF in the VM.

could you both try to set the machine type to 'pc-q35-3.1'

there were some changes in qemu 4 (which should be fixed with 4.0.1 or 4.1, depending what we will package) that can be
fixed with temporarily changing to a 3.1 machine type

Setting machine type to `pc-q35-3.1` does not seem to change the behavior. It still freezes at `Guest has not initialized the display (yet)` when setting `pcie=1` on other VFs.

I forget to mention that my NICs are Intel X722.

I have the same issue, cannot start second VM if pcie=1 enabled.

dcsapak · Dec 3, 2019

could you try the newer kernel from the repos (5.3)?
maybe it is a driver issue...

i have here an I350 with sr-iov, and i can passthrough multiple vfs in either pci/pcie mode without problems....
