Hi, I have a PCIe USB card which is exported to the bhyve vm using passthrough. I have tried to use the card in Ubuntu, Debian 8 and Centos 7. Each time the OS has given a segmentation fault on bootup and killed the bhyve session. This is what i get in the bhyve-log: Aug 17 01:49:39: initialising Aug 17 01:49:39: [loader: grub] Aug 17 01:49:39: [uefi: no] Aug 17 01:49:39: [cpu: 1] Aug 17 01:49:39: [memory: 512M] Aug 17 01:49:39: [hostbridge: standard] Aug 17 01:49:39: [com ports: com1] Aug 17 01:49:39: [uuid: 09a84879-8156-11e7-b407-0cc47adeccc0] Aug 17 01:49:39: [utctime: no] Aug 17 01:49:39: [debug mode: no] Aug 17 01:49:39: [primary disk: /dev/zvol/vmpool/os9] Aug 17 01:49:39: [primary disk dev: custom] Aug 17 01:49:39: initialising network device tap2 Aug 17 01:49:39: adding tap2 -> bridge1 (lannetwork) Aug 17 01:49:39: booting Aug 17 01:49:39: create file /tank/vm/openhab1/device.map Aug 17 01:49:39: -> (hd0) /dev/zvol/vmpool/os9 Aug 17 01:49:39: /usr/local/sbin/grub-bhyve -S -m /tank/vm/openhab1/device.map -M 512M -r hd0,msdos1 openhab1 Aug 17 01:49:42: [bhyve options: -c 1 -m 512M -AHP -U 09a84879-8156-11e7-b407-0cc47adeccc0 -S] Aug 17 01:49:42: [bhyve devices: -s 0,hostbridge -s 31,lpc -s 4:0,virtio-blk,/dev/zvol/vmpool/os9 -s 5:0,virtio-net,tap2,mac=58:9c:fc:07:cc:2d -s 6:0,passthru,129/0/0] Aug 17 01:49:42: [bhyve console: -l com1,stdio] Aug 17 01:49:42: starting bhyve (run 1) Aug 17 01:49:44: bhyve exited with status 139 Aug 17 01:49:44: destroying network device tap2 Aug 17 01:49:44: stopped The USB card works fine on the host and is detected by the xhci driver. The card is "Inateck Superspeed 4 Ports PCI-E to USB 3.0 Expansion Card - Interface USB 3.0 4-Port" (https://www.amazon.com/gp/product/B00B6ZCNGM) ppt3@pci0:129:0:0: class=0x0c0330 card=0x11001b73 chip=0x11001b73 rev=0x10 hdr=0x00 vendor = 'Fresco Logic' device = 'FL1100 USB 3.0 Host Controller' class = serial bus subclass = USB Any idea how can i use this card in a linux vm? Thanks
