with multiple PCI devices the .conf file gets "rewritten" and the VM no longer boots

[Joris L.]

While struggeling with PCI passthrouhg (it does work, eventually) i found something peculiar.

Sometimes the VM would not boot because the PCI.id for a device was alread in use. This was because the pci-id for the vga and the audio were written as the same. So instead of 0000:17:0.0 and 0000:17:0.1 the now both were written as 0000:17:0

I consider this to be a possible bug

This problem condition is only visible when bootig from the console with qm start <vmidhere> Because of it i spent a lot of time chasing ghosts. Lesson learned, stick to my own principles, use a shell.

Could you post your VM config ('qm config <vmid>') and the exact output of 'qm start', as well as a 'pveversion -v'?

 

[Joris L.]

this happens for any VM i attempt passthrough with for both GPU and Audio (same ID.x)
latest VE 6.2 fully updated
qm start simply states the device was allready assigned/associated, which is how i found out about this happening in the first place

I understand, but can you please still post your VM config, so I can try to reproduce your issue? 'qm showcmd <vmid>' would also be helpful.

this is no longer an issue now, i have absolutely no idea why not anymore. If it resurfaces i will update the thread.

to know, i have not customized vmid.conf in any way, simply using the web interface. The only manual configurations i made were the corrections required after observing the 'already in use' message using qm start <vmid>

i will try to simulate this and post the <vmid>.conf
