Unable to parse bus id ? #13

Open awgn opened 1 month ago

awgn commented 1 month ago

I’m encountering an error while running the example that enumerates PCI devices on Linux Ubuntu, running in a Multipass instance on macOS Ventura (M2).

The error returned is:

pci bus enumeration error: error while parsing value: bus ID is invalid hex: '0000:00'

The output of lspci is the following:
