thrroow Posted December 22, 2020 Share Posted December 22, 2020 I can only get 2 of the 4 ports to pass through to this VM. I have tried with the ACS override on/off, and with multifunction on/off (2 groups of 2 or 4 individual devices). Any ideas? I had no special settings and all 4 devices individually assigned (no multi) to a VM in 6.8.3, but didn't work when I upgraded to 6.9.0-rc1 for some reason. <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x05' slot='0x00' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x1'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x06' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x03' slot='0x00' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x06' slot='0x00' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x1'/> </hostdev> IOMMU group 17: [111d:8018] 03:00.0 PCI bridge: Microsemi / PMC / IDT PES12N3A 12-lane 3-Port PCI Express Switch (rev 0e) IOMMU group 18: [111d:8018] 04:02.0 PCI bridge: Microsemi / PMC / IDT PES12N3A 12-lane 3-Port PCI Express Switch (rev 0e) [8086:10d6] 05:00.0 Ethernet controller: Intel Corporation 82575GB Gigabit Network Connection (rev 02) [8086:10d6] 05:00.1 Ethernet controller: Intel Corporation 82575GB Gigabit Network Connection (rev 02) IOMMU group 19: [111d:8018] 04:04.0 PCI bridge: Microsemi / PMC / IDT PES12N3A 12-lane 3-Port PCI Express Switch (rev 0e) [8086:10d6] 06:00.0 Ethernet controller: Intel Corporation 82575GB Gigabit Network Connection (rev 02) [8086:10d6] 06:00.1 Ethernet controller: Intel Corporation 82575GB Gigabit Network Connection (rev 02) -device qxl-vga,id=video0,ram_size=67108864,vram_size=67108864,vram64_size_mb=0,vgamem_mb=16,max_outputs=1,bus=pcie.0,addr=0x1 \ -device vfio-pci,host=0000:05:00.0,id=hostdev0,bus=pci.1,multifunction=on,addr=0x0 \ -device vfio-pci,host=0000:05:00.1,id=hostdev1,bus=pci.1,addr=0x0.0x1 \ -device vfio-pci,host=0000:06:00.0,id=hostdev2,bus=pci.3,addr=0x0 \ -device vfio-pci,host=0000:06:00.1,id=hostdev3,bus=pci.4,addr=0x0.0x1 \ -sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny \ the above gives me: Quote Link to comment
