ccsnet Posted June 5, 2023 Share Posted June 5, 2023 Hi all,  I hope you can help - i've been looking at this all day.  I'm trying to get VNC to work as primary on a Windows 11 VM and the NVIDA card as secondary.  I know from this post that my Nvida is most likley failing because Unraid it making it look split at the bus level.  To that end I've tried to edit this...   <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/> </source> <rom file='/mnt/user/isos/vbios/gpuvbiosMSI1060.rom'/> <address type='pci' domain='0x0000' bus='0x05' slot='0x00' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x02' slot='0x00' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x06' slot='0x00' function='0x0'/> </hostdev>  to this...  <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/> </source> <rom file='/mnt/user/isos/vbios/gpuvbiosMSI1060.rom'/> <address type='pci' domain='0x0000' bus='0x05'

<address type='pci' domain='0x0000' bus='0x05' slot='0x00' function='0x0'/> </hostdev>  ...but Unraid will not have it so I assume its a 'me' issue.  Quote XML error: Attempted double use of PCI Address 0000:05:00.0  Can some one assist me getting the xlm right please but also may be explain where I have gone wrong ?  Thanks in advance  Terran    FULL XML  <?xml version='1.0'

Note multifunction on first part and function 0x1 on last part. Quote Link to comment
ccsnet Posted June 5, 2023 Author Share Posted June 5, 2023 Thank you for that - tested and working... I can see the change you have made but do not fully understand it.  Would you mind explaining it as I'm trying to learn this aspect.  Is the type PCI lines refering to the phiscal slots then ?  Thanks  T Quote Link to comment

The pci line is the id within the vm. But they need to be unique. So the card id is 0000:05:00 with two functions 0 and 1  0 is video and 1 is audio part of the pci device Quote Link to comment
