Hello;
I'm trying to passthrough a firewire pci card to a windows 7 64 guest.
Without passthrough, the vm boots with everything working normally.
Here are my specs:
uname -a:
FreeBSD 11.1-STABLE #0 r328025M: Wed Jan 17 18:30:26 -03 2018
root@Papi.lobos:/usr/obj/usr/src/sys/LOBO amd64

PCI card (already attached to ppt0)

rev=0xc0 hdr=0x00 vendor = 'VIA Technologies, Inc.'
device = 'VT6306/7/8 [Fire II(M)] IEEE 1394 OHCI Controller'
class = serial bus

Starting the vm with VNC:
bhyve -A -P -H -c 4 -S -s 0,amd_hostbridge -s
3,ahci-hd,/Vmachines/disk.img,sectorsize=512 -s
4,ahci-cd,/Extra/Isos/Windows/Windows_7/null_dvd.iso -s
7,passthru,4/7/0 -s 10,virtio-net,tap0 -s
11,fbuf,tcp=0.0.0.0:5900,,w=1600,h=900,wait -s
20,xhci,tablet -s 31,lpc -l
bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd -m 8G -H -w
WIN-764
fbuf frame buffer base: 0xa42e00000 [sz 16777216] Assertion
As soon as I try to connect, the VM aborts with:
failed: (error == 0), function modify_bar_registration,
file /usr/src/usr.sbin/bhyve/pci_emul.c, line 491. Abort trap
Starting the vm without VNC:
bhyve -A -H -P -c 4 -S -s 0,amd_hostbridge -s
3,ahci-hd,/Vmachines/disk.img,sectorsize=512 -s
4,ahci-cd,/Extra/Isos/Windows/Windows_7/null_dvd.iso -s
7,passthru,4/7/0 -s 10,virtio-net,tap0 -s
20,xhci,tablet -s 31,lpc -l
bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd -m 8G -H -w
WIN-764
VM exits with:
Assertion failed: (mr->name == memp->name), function
unregister_mem, file /usr/src/usr.sbin/bhyve/mem.c, line 265.
Abort trap
Same thing happens without "-A -H -P" on bhyve command line.
Would anybody have any suggestions on what else I could try?
Thanks,
